Frequently asked questions

Cyclone filters

How does a cyclone filter system work?

Cyclone filter systems separate dust by generating a vacuum inside the dustbin. Due to this underpressure, the dust is sucked in via the side inlet of the cyclone filter. Because the cyclone filter has a rotated inside, it pushes the dust outwards to the inner walls. This phenomenon is also centrifugal force. Because there is a vacuum in the dustbin, the rotating dust is pulled down. The centrifugal forces and the vacuum create a miniature cyclone and thus separate the dust from the air. Because the dust is heavier than the air, only the dust will be drawn to the bottom of the dustbin. The cleaner air (up to 99% cleaner) leaves the filter system through the top outlet.

How well do cyclone filters work?

In three words: they work great. We have put cyclone filter model 3 to the test by filtering out dust from milled sheets of MDF. MDF dust is very fine and resembles the particle structure of baking powder. In our test 96% of that fine MDF powder was filtered and did not end up in our vacuum machine. That means that the vacuum bag needs to be changed 25 times less often than without a cyclone filter.

Suppose you have a Bosch AdvanceVac 20 vacuum cleaner and the vacuum bags cost between €2,50 and €4,50 each (depending on the store + shipping costs). When you normally use up one bag a week, with a cyclone filter this is reduced to only one bag every 25 weeks or once every six months (approximately). This means that on a yearly basis you don’t have to buy 52 vacuum bags but only two.

When a vacuum bag costs €2,50 each, then you don’t spend €130 on vacuum bags on an annual basis, but only €5. That will save you €125 year after year. When a vacuum bag costs €4,50 each, it is even a bigger saving of €225 annually.

In addition, it ensures that full suction power is maintained. Also, the vacuum engine does not wear out as fast, because far less dust gets into the vacuum cleaner itself. Your vacuum cleaner will therefore last longer.

In what circumstances can I use a cylone filter?

A cyclone filter can be used for all types of work where dust is released. Cyclone filters can be used with sanders, mitre saws, table saws, routers, wall grinders, floor grinders, CNC routers, sand blasting cabinets, and drilling machines to name just a few. Click on the ‘Application’ tab or click here for more information.

Which filter do I need?

All filters have different filter capacities. For example, cyclone filter model 2 can handle 240m3 air per hour whereas cyclone filter model 3 can handle up to 280m3 air per hour. In the comparison tab there is an overview of the different cyclone filters with their capacities.

Which cyclone filter you need depends on the technical specifications of your vacuum cleaner. If you look up the specifications you will probably find some information regarding the maximum airflow the vacuum cleaner can handle.

For example, the Bosch AdvanceVac20 can handle 70 liters of air per second. That is 252,000 liters per hour (70 liters x 3.600 seconds) and amounts to 252m3 air per hour (252.000 / 1.000). Cyclone filter model 3 is therefore the best choice for the Bosch AdvanceVac 20 vacuum cleaner.

Why is there a ring inside the 20 liter dustbin?

The inner ring is for reinforcement of the dustbin. The ring falls exactly in the middle of the dustbin, because the dustbin tapers slightly downwards. The ring precents the dustbin from collapsing under even the most extreme vacuum pressures. Most plastic dustbins, and even some thin-walled metal dustbins collapse when put under vacuum pressure.

Which dustbin do I need?

The type of dust bin that is most suitable for your needs depends on four things: (a) the power of the (professional) vacuum machine and the inner diameter of the dust port, (b) the type of dust being filtered, (c) the amount of dust being filtered, and (d) the type of cyclone filter that will be used.

a) (Professional) vacuum machine and inner diameter dust port

Do you have a powerful construction vacuum cleaner (Festool, Makita, Bosch blue, etc.) and does dust needs to flow through a relatively narrow  dust port (smaller than 30mm)? Then a metal dustbin is recommended. Powerful (professional) vacuum machines generate a high negative pressure in the dustbin. If the airflow is cut off by a too narrow dust port, then the vacuum cleaner motor will continue to operate at full speed, resulting in an even greater negative pressure in the dustbin. Metal dustbins are therefor more suitable for that kind of application.

b) Type of dust

For example, if large wood chips are sucked up, the 20 liter dust bin will quickly become full, because large wood chips do not compress well. In those cases, the 60 liter metal dust bin would be the best solution.

c) The amount of dust

Some work releases more dust than others. Milling, for example, sheets of MDF provides a lot of dust. The 20 liter dust bin would in that case be a bit too small.

d) Type of cyclone filter

Cyclone filters model 2 and model 3 can be mounted onto the 20 liter dust bin aswell as onto the 60 liter metal dust bin. The metal cyclone filter can also be mounted onto the 20 liter dust bin and the 60 liter metal dust bin. Almost always is the metal filter mounted onto a metal dust bin, because otherwise the grounding capabilities of the metal cyclone filter would be negatively effected by not being able to ground the plastic 20 liter dust bin. The XL cyclone filter is too big to be mounted onto the 20 liter dust bin. The 60 liter metal dust bin would be the way to go.

My system doesn’t filter properly, what can I do?

A cyclone filter system that is not working properly can have two causes:

  • The underpressure in the collection vessel is not correct.
  • The dust is too light and therefore cannot be drawn to the container.

In 95% of the cases, the cause is a vacuum inside the dustbin that is too low. This can be for a number of reasons:

  • The suction power of the vacuum machine is not strong enough to generate the necessary basic vacuum pressure. This is usually only the case when the filter of the vacuum cleaner is clogged or if the vacuum cleaner motor is no longer functioning properly.
  • There is an air leak in the filter system. Consider, for example, a lid that does not close properly, a gap between the base of the filter and the lid, or there is an air leak somewhere in the hose.

If you have a filter system with a anti-crush pressure valve, poor performance may be due to the vacuum valve opening too often. For a cyclone filter system to work properly, the anti-crush pressure valve must remain closed during normal use, otherwise dust will still end up in the vacuum cleaner. A valve that opens continuously is a sign that A. the spring resistance isn’t set correctly or B. the negative pressure is too high (for example, because dust is being sucked through a dust port that is too small). In those cases, a number of things can be done:

  • Tighten the adjustment nut to increase the spring resistance. Turn the adjustment nut with a maximum of two rotations each time and then test the system. This prevents the pressure valve from being adjusted too tightly causing the valve not to open in a timely manner and thereby crushing the dustbin. For our blue dustbins the adjustment nut should be set slightly below the center of the threaded portion of the bolt.
  • Lower the suctions power of the vacuum cleaner. Not too low, because there must be a basic vacuum pressure in the dustbin for proper operation.
  • Use a nozzle with variable air inlet, for example our Pro-X nozzle. The nozzle can admit air from the outside by means of a slide, which reduces the vacuum pressure.
  • Use a shorter hose on the side inlet of the filter. A hose creates air resistance: the longer the hose, the greater the air resistance. Greater air resistance creates greater a vacuum pressure.
  • Use a hose on the side inlet of the filter with a larger inner diameter and a larger nozzle. As a result, more air can flow through the system which reduces the vacuum pressure.
  • Reduce the number of bends in the hose that is attached to the side inlet of the filter. Every bend creates air resistance and thereby a greater vacuum pressure.

If you want to use a filter system with anti-crush pressure valve on machines whose dust port has an inner diameter smaller than 30mm and you do not have a vacuum cleaner with adjustable suction power, then we recommend using a nozzle with variable air inlet, for example our Pro-X nozzle. Smaller dust ports will cause excessive vacuum pressure, causing the valve to open continuously.

Vacuum hoses

What is the difference between all your vacuum hoses?

Our vacuum hoses differ in four respects: (1) maximum air flow, (2) flexibility, (3) robustness, (4) durability and (5) grounding capabilities.

1) Maximum air flow

Hoses with a larger diameter can handle a bigger airflow than hoses with a smaller diameter. There are three starting points for determining the required diameter:

  1. The longer the hose must be, the larger the inner diameter of the hose must be. By extending the hose, the air resistance also increases. With very long hoses, this can lead to a reduction of suction power. This will be less of an issue when the inner diameter of the hose is bigger.
  2. The greater the power of the vacuum cleaner, the bigger the inner diameter of the hose must be. All vacuum cleaner engines have a predetermined amount of air that needs to pass through. A hose that is too narrow will prevent enough air going through. Not only does this result in reduced suction power, but also resulting in the risk over overheating the vacuum engine and more wear and tear of the engine.
  3. More bends in the hose will require a hose with a larger inner diameter. Bends causes air resistance resulting in lower suction power.

More information on dust collectors and types of hoses can be found here: https://www.youtube.com/watch?v=0NmMoIYIsr8

Various cyclone filter sets come with the standard vacuum hose. We have put the 5 meter standard vacuum hose to the test and 75% to 80% of the suction power remains. More than enough for a cyclone filter system to function perfectly. If you prefer not to lose any suction power then you can opt for a vacuum hose with an innerdiameter of 38mm or 50mm.

2) Flexibility

A flexible hose is needed when you are using, for example, a sanding machine, or handheld router. These activities require a hose that does not interfere with the movement of the machines. For all hoses it is indicated what their degree of flexibility is: 1/5 = stiff | 5/5 = extremely flexible.

  • The standard vacuum hose (inner diameter 32mm) is a flexible hose and is suitable for work where the hose must be able to move easily: 4/5.
  • The Industrial vacuum hose (inner diameter 38mm) is a flexible hose and is suitable for work where the hose must be able to move easily: 4/5.
  • The Superflex R vacuum hose (inner diameter 50mm) is an extremely flexible vacuum hose and can bend effortlessly in all directions: 5/5.

3) Robustness

  • The standard vacuum hose is a sturdy and flexible hose. The flexibility of the hose is due to the fact that it does not have a reinforcing external spiral. If the vacuum hose is being stepped on, it will be pressed in but will return in its original form.
  • The Industrial vacuum hose is a sturdy and flexible hose. The flexibility of the hose is due to the fact that it does not have a reinforcing external spiral. If the vacuum hose is being stepped on, it will be pressed in but will return in its original form.
  • The Superflex R vacuum hose has a copper spiral and is therefore very strong and extremely flexible. It’s the most flexible hose.

4) Sustainability

If abrasive material needs to be filtered then hoses with smooth inner walls are recommended. The thicker the walls of the hose, the longer it will last.

  • The standard vacuum hose has smooth inner walls (thickness 0.8mm).
  • The Industrial vacuum hose has smooth inner walls (thickness 1mm).
  • The Superflex R vacuum hose has ribbed inner walls (thickness 0.55mm).

5) Grounding capabilities

Where dust is being sucked up, there is a chance that static electricity will be generated. This is caused by dust rubbing against the inside walls of, for example, a vacuum hose or filter thereby creating friction. This friction gives the dust a different electrical charge than the surface on which it rubs. The extent to which static electricity is built up highly dependents on the material that is being sucked up. For example, sucking up plastic chips generates more static electricity than, for example, your ordinary wood chips.

  • The standard vacuum cannot be grounded.
  • The Industrial vacuum cannot be grounded.
  • The Superflex R vacuum hose can be grounded because it has a copper spiral.

How much vacuum power is lost when I use the ready-to-go 5 meter vacuum hose?

When using a cyclone filter, the total length of the vacuum hose is essentially extended, because an extra hose is added. In most cases, this means that the air resistance increases. We use a Bosch AdvanceVac20 consumer-grade vacuum cleaner and the loss of suction power is between 15% and 20%. More than enough suction power remains for the cyclone filter system to function perfectly. Even with most standard household vacuum cleaners there is enough suction power left.

We have vacuum hoses with different diameters. If you do not want to loose any suction power, then you can opt for a vacuum hose with a larger diameter. The different suction hoses can be found here.

Can I also use a vacuum hose from an old household vacuum cleaner to connect to the side inlet of cyclone filter model 2 or model 3?

Yes, that is possible. If the outer diameter of the hose is somewhere between 35mm and 40mm then you can use a 50mm>40mm rubber reducer to connect the hose to the side inlet of cyclone filter model 2 or model 3.

Vacuum cleaners

How do I attach my vacuum cleaner to the cyclone filter?

The vacuum nozzle at the end of the hose of your vacuum cleaner is inserted in the top opening of the filter. The top opening has an inner diameter of 50mm. Most vacuum nozzles have an outside diameter between 32mm and 40mm. This means that the top opening must be reduced which can be done with the use of a rubber reducer. There are two versions: ’50mm>32mm to 34mm’, and ’50mm>35mm to 40mm’. Both can be found here.

If you order a cyclone filter set then both reducers are included so that all vacuum nozzles from 32mm to 40mm can be connected to the top opening of the cyclone filter.

Can I also hook-up an standard household vacuum cleaner to the cyclone filter?

Yes, that is possible. It is not necessary to purchase a special (industrial) vacuum cleaner. Even with a standard hosehold vacuum cleaner, the cyclone filters work very well. Although it is true that (consumer-grade) industrial vacuum cleaners can generate a greater underpressure and therefore perform a little better.

Why would I buy from you guys when I can order filter in Asia?

Three reasons: for speed, for service and for peace of mind.

(1) Speed

Orders before 6 pm on business days will be delivered within two days (depending on the destination country). Shipping time from Asia to Europe is usually between 21  and 30 days, but can be even longer. This is a lot longer than the Asian retailers often mention in there ads, despite the fact that they advertise with 10 to 15 days. Their 15 days are often business days, not counting the weekends. Also, the ’15 day delivery’ starts when the order has been fully processed. But after ordering it can take up to 5 days before it is fully processed and given to the carrier. In the end, it usually takes an average of 3 to 4 weeks for a product from Asia reaches Europe. If the package is held by customs, then another five days needs to be added up to the delivery time as well as additional cost for clearing customs. For The Netherlands: 21% Dutch VAT on purchases higher than € 22 + € 13 administration costs. The administration costs of an EMS shipment are even higher: €17,50. A filter of €25 (including shipment to The Netherlands) could end up costing €38,63. We have cyclone filters that start as low as €24,95.

(2) Service

We do all the work for you. This means that all cyclone filter combinations, and cyclone filter sets have been fully prepared by us . You do not have to mark the cutouts yourself, drill the mounting holes and cut the big dust hole. After receiving your cyclone filter combination, of cyclone filter set all you have to do is attach the cyclone filter to the dustbin with of a couple of fastners. You are up-and-running within 5 minutes.

(3) Peace of mind

Products from Asia regularly arrive broken. They are hardly packaged properly, which means that they often do not survive their thousands of kilometers of adventure. If you receive a Asian product that is broken, you need to contact a foreign customer service. Our own experience is that it takes upto 7 days before they resend your order. This automatically results in you waiting another 3 to 4 weeks before your new order arrives. Adding it all up, in case of a broken product you end up waiting 49 to 69 days.

At Cycloonfilters.nl we carefully inspected our products, and package them properly before they are sent. If something is not entirely in order, you will receive a new product within 48 hours of return. Guaranteed!
