Vacuum Suction Filters: Selection and Maintenance
EUROTECH TAIWAN, is known for its modular construction system when it comes to vacuum components. If it is suction plates, valves, fittings and attachment, you need it, we got it. Most existing vacuum lifters and vacuum handling systems have vacuum filters installed. Over the years we have developed an large range of vacuum filters who should be installed in order to keep dirt and dust particles out of the vacuum system where they can cause malfunction of the system.
Select a vacuum filter by checking the required airflow at the system’s operating vacuum, the pressure drop across the filter, and the connection size. Matching the port size alone does not establish whether a filter is suitable for a vacuum pump, side-channel blower or ejector.
Assess the filter’s resistance together with the hoses, valves and fittings in the circuit. Confirm that the system can reach the required vacuum at the suction cups within the required evacuation time. Follow the specified flow direction and mounting position.
If the circuit uses compressed air to release the workpiece, confirm the pressure limits and operating conditions for the exact filter model. The BVF-D design described below addresses brief pressure pulses during quick release. This does not mean that every filter series can be pressurized or that its cartridge can be cleaned with compressed air.
The most common filter is the type BVF. The filter is made from sheet metal and powder coated. Installed is an replaceable filter cartridge which is easy to clean or if needed easy to replace. The connection thread starts with G 3/8” inside thread and goes up to G 4” inside thread. The BVF range covers 11 vacuum filters with flow range from 12 m³/h up to 1260 m³/h. More details you find in our catalogue.
Vacuum Filter Serie BVF and BVF-D
Serie BVF
Vacuum Filters in Use
The series BVF-D covers an range of 6 vacuum filters with connection from G 3/8” up to G 11/4”. They come with an additional installation which allow compressed air to be used for quick release as done when high speed release of the work piece is needed. Compressed air is used to break down the high vacuum in the system. Here the cover of the vacuum filter is the weak part. Due to an inner installation with treaded pin and installed flat knurled nut ( DIN 467 ) the cover is secured against short time pressure ( impulse pressure ) in the filter housing which occurs when using compressed air for quick ventilation.
The Filter is made from sheet metal and powder coated. Installed is an replaceable filter cartridge which is easy to clean or if needed easy to replace. The connection thread starts with G 3/8” inside thread and goes up to G 11/4” inside thread. The BVF-D range covers 6 vacuum filters with flow range from 12 m³/h up to 108 m³/h. More details you find in our catalogue.
Serie BVF-D
Vacuum Filters in Use
Our series BVF-K are light weight filters with replaceable filter cartridge made of Polyethylene. The housing is made of PVC with an clear ( transparent ) filter housing. Installed is an replaceable filter cartridge which is easy to clean or if needed easy to replace. The connection thread starts with G 1/8” inside thread and goes up to G 3/4” inside thread. The BVF-K range covers 5 vacuum filters with flow range from 2,7 m³/h up to 35,7 m³/h. No Tools are needed to open and clean the vacuum filter. More details you find in our catalogue.
Vacuum Cup Filter Serie BVF-K
Fine filter type BFF are installed directly into thread of the connecting nipple or into the threaded hole of the suspension bolt or suction cup. There are 3 types available. G 1/8”, G ¼” and G 3/8” are made from PVC with stainless steel mesh as filter element. More details you find in our catalogue.

Vacuum filter inspection and maintenance
Set inspection intervals according to the dust load, operating hours and observed filter condition, while following the maintenance requirements for the specific model. A filter used in a dusty process may need attention sooner than one used in a cleaner environment.
- Follow the equipment instructions for isolating the system and releasing vacuum or pressure before opening the filter.
- Inspect the cartridge for contamination or damage, and check the housing seals for damage and correct seating.
- Clean the cartridge only with a method permitted for that model. Replace it when required by its condition or the manufacturer's instructions.
- After reassembly, check the connections, specified flow direction and mounting position.
Record the inspection date, cartridge condition and any cleaning or replacement work. Compare evacuation time and the vacuum reached at the suction cups with a known-good baseline under the same operating conditions. Use these records to adjust the inspection interval and investigate any loss of performance.
