Cassette Filter
Deep-pleated cassette filtration for air intake and industrial ventilation.
Choose M6, F7, F8 or F9. Each grade has a rated airflow of 3000 m³/h, with grade-specific initial resistance and dust-holding capacity.

cassette performance.
Deep-pleated construction
Thermo-embossed media forms the deep pleats within the cassette filter element.
Two airflow values
Rated airflow is 3000 m³/h. Maximum recommended airflow is 3750 m³/h; these are shown separately for selection.
Grade-specific performance
Compare initial pressure drop and dust-holding capacity for M6, F7, F8 and F9 alongside the required filtration grade.

Please confirm filter dimensions and operating airflow before ordering.
Confirm the mounting fit.
Match the filter to the housing and retaining arrangement.
- Mounting check
- Face dimensions, depth and seal contact
- Before ordering
- Send a drawing or an existing-filter photo
Measure the installation.
Confirm the filter.
Measure the existing filter and mounting slot. Include clearances, seals and retaining details.
Provide airflow, allowable pressure drop, temperature and any humidity or liquid exposure.
Share the quantity, required specification and photos or drawings. Non-standard dimensions are reviewed before quotation.
Applications & system integration
Engine and turbine air intake
Review the filter dimensions, mounting interface and operating requirements against the equipment specification.
Industrial process air
Particle filtration for compatible industrial air-handling systems, with grade selected to suit the process requirements.
HVAC and recirculation
Cassette filtration in compatible air intake, exhaust and recirculation systems.
Fit correctly. Monitor in service.
Before installation
Check dimensions and mounting fit. Follow the airflow arrow and handle the filter by its frame, keeping pressure off the media.
Seat & secure
Apply even retaining pressure. Check the perimeter seal and filter-bank joints for bypass gaps.
Track condition
Record initial pressure drop at the operating airflow. Inspect the frame, filter pack and seals during maintenance.
Follow system limits
Plan replacement using pressure-drop monitoring and equipment maintenance requirements. Replace damaged filters promptly.
Product questions, answered.
Which grades are available?
M6, F7, F8 and F9 are listed. Select the grade required by your system specification.
What is the difference between the two airflow values?
3000 m³/h is the rated airflow; 3750 m³/h is the maximum recommended airflow.
What should I send to confirm fit?
Send dimensions, a drawing or photos of the existing filter and housing, the mounting arrangement, required grade and operating airflow.
What information is needed for a quotation?
Send your required grade, dimensions, quantity, operating airflow and installation details. Include drawings or photos of the housing where available.
