High Efficiency Filters
Complete compressed-air filter assemblies from approximately 20 to 1700 CFM for workshops, garages, manufacturing facilities and larger industrial systems.
Choose the Correct Compressed Air Filter
Filter selection should be based on actual compressor airflow, working pressure, connection size, the contaminant that needs removing and the final air quality required.
The live product section below is restricted to complete filter assemblies. Replacement filter elements belong in the separate filter-element range and are deliberately excluded here.
The current complete-filter range spans approximately 20 to 1700 CFM, with selected housings rated up to 16 bar.

How to Size a Compressed Air Filter
Actual Delivered Airflow
Size from the compressor's delivered CFM rather than motor kW or theoretical displacement.
Working Pressure
Confirm the filter is suitable for the system pressure and use the correct performance data where pressure affects rated flow.
Connection Size
The BSP connection must suit the pipework, but thread size alone does not confirm sufficient flow capacity.
Required Air Quality
Select the filtration grade or staged combination according to the contamination and downstream process.
What Do the Different Filter Grades Do?
3 Micron Pre-Filter
Used as an initial stage for larger particles and bulk contamination before finer treatment.
1 Micron General Filter
General compressed-air filtration for workshops, garages, pneumatic machinery and many industrial applications.
0.01 Micron Fine Filter
Fine coalescing filtration for applications requiring reduced microscopic particulate and aerosol contamination.
High-Efficiency Oil Removal
Final-stage treatment for applications requiring extremely low oil carryover. Correct upstream treatment remains essential.
Do I Need More Than One Filter?
Often, yes. Compressed-air treatment commonly uses more than one filtration stage so each element deals with the type and quantity of contamination it is designed to remove.
- Pre-filtration removes larger contamination before finer filters
- General-purpose filtration improves routine workshop air quality
- Fine coalescing stages reduce smaller particles and oil aerosols
- Activated-carbon treatment can be added where oil-vapour reduction is required
- The exact sequence depends on compressor type, dryer technology and required final air quality
High Efficiency Filter Housing Construction
The current range uses high-grade die-cast aluminium housings with internal and external protective treatment and an epoxy-baked compressed-air-blue finish.
- Die-cast aluminium construction
- Internal and external Alu-Chrome treatment
- Epoxy baked coating in RAL 5015 compressed-air blue
- Brass automatic drain assembly on selected housings
- 6 mm condensate discharge provision on the described range
- Optional differential-pressure indication depending on housing
Why Low Pressure Drop Matters
Every restriction in a compressed-air system costs pressure. As filters become undersized or contaminated, the compressor may need to produce a higher discharge pressure to maintain the required pressure downstream.
The existing high-efficiency range uses pleated filter media to increase filtration surface area and help reduce pressure drop while maintaining filtration performance.
Filter Inspection & Element Replacement
- Inspect filters regularly for pressure drop and condensate drainage
- Replace internal filter elements at the required maintenance interval
- Check automatic drains are operating correctly
- Investigate abnormal pressure loss across the housing
- Keep a record of installed housing and element references
- Safely isolate and fully depressurise the system before servicing
Information to Check
- Compressor delivered airflow / CFM
- Normal and maximum working pressure
- Pipe and connection size
- Required filtration grade
- Existing filter or housing reference
- Required downstream air quality
- Dryer type and position within the treatment system
- Available installation and maintenance space
High Efficiency Filter FAQs
What airflow range is available?
The current complete-filter range covers approximately 20 to 1700 CFM, depending on housing, connection and filtration grade.
What is the difference between GP, OR and AC?
GP is general-purpose filtration, OR is oil-removing filtration and AC is activated-carbon treatment. They perform different roles within a staged treatment system.
Can I choose a filter just from the BSP thread?
No. The filter must also have sufficient airflow capacity, the correct pressure rating and the required filtration grade.
Why allow spare filter capacity?
Extra capacity can help reduce pressure drop, cope with short demand peaks and provide room for future system growth.
Are replacement elements included on this page?
No. This page is specifically for complete filter housings and assemblies. Replacement elements are kept in the separate filter-element range.
How often should the filter element be changed?
Replacement depends on operating hours, contamination, pressure drop and the product's maintenance guidance. Filters should be inspected regularly and serviced before restriction affects performance.
Can Compressed Air Systems UK help size a filter?
Yes. Call 0121 753 3330 with the compressor model, delivered airflow, pressure, pipe size and required air quality.
