Our comprehensive range of silicone free compressed air and gas filtration products for use in almost every industrial
environment.
By using in-house research and development facilities we create high quality filtration
products which satisfy the increasing demands of today’s sophisticated market. Within our standard range of
threaded filters we offer 14 models with connections from 1/4" to 3" (A20-A308) offering flow capacities up to
1531 scfm (43.33m3/min). These models incorporate the unique ‘push on’ filter element, which reduces
maintenance time and allows the filter to be located in the most confined places.
These filters are manufactured using die-cast aluminium housings for pressure ratings up
to 16 barg (232 psig). They are a proven success due to the inclusion of such features as differential pressure
indicators which allow continuous monitoring of filter performance. All filter
bodies are coated with blue polyester finish to eliminate corrosion.

Technical
Notes
1. Threaded filters are manufactured from aluminium and carry the CE mark.
2. Threaded connections are BSP parallel to ISO7/1 or NPT to ANSI B2.1 if supplied within North America.
3. Filter element end caps are colour coded. Direction of air flow, inside to out, through filter element.
4. Activated carbon filters must not operate in oil saturated conditions and will not remove certain types of gases including carbon monoxide and carbon dioxide.
5. Grade AC elements must be changed periodically to suit application but at least every 6 months.
6. Activated carbon towers for larger applications are available to order. Please refer to activated carbon tower leaflet.
7. Pop up indicators are supplied with models A20 (grade) and A30 (grade). Differential pressure indicators are fitted to models A55 (grade) to A308 (grade), part number 55DPIW (with the
exception of grade AC).
8. Models A20 (grade) and A30 (grade) supplied complete with condensate level sight glass.
9. Float operated automatic drain valves, model AD16 with manual override facility are fitted to all standard models. Semi automatic drain valves, model SADV 25 with manual override facility
are fitted to all AC grade filters.
10. Mounting brackets are available for all models, see accessory product leaflet.
11. All filter bodies are electrophoretically painted and then coated with blue polyester powder paint finish to eliminate corrosion.
12. Threaded filters and filter elements are suitable for use with mineral and synthetic oils plus oil free compressed air applications.
13. For larger flow application please refer to the flanged filter leaflet.
14. Threaded filters and filter elements are silicone free.
