Use cases & applications
Oil vapour and odour removal
Activated carbon adsorbs the oil vapour and smell left after a 0.01 µm coalescing element.
Food, beverage and pharmaceutical air
Air in contact with product is usually passed through a carbon stage after the 0.01 µm stage.
Protecting the carbon
Liquid oil saturates carbon early, so change the 0.01 µm element ahead of it at the same service.
Change interval
Carbon does not show a pressure drop when spent. Change it at least every 1,000 operating hours or six months, and sooner if the air smells of oil.
Frequently asked questions
Is this a genuine Pneumatech part?
No. It is an aftermarket element made to fit. It is not made by or affiliated with Pneumatech, Quincy or Chicago Pneumatic; the number 2258290142 is shown only so you can match the part you are replacing.
How do I know it fits?
Check the number on the old element or in the filter's parts list. If it reads 2258290142, or the HiFi equivalent SI 54083, this is the replacement.
Do I need a 0.01 µm element in front of it?
Yes. Activated carbon is meant for oil vapour, not liquid oil or particles, so it must sit after a 0.01 µm coalescing element. Without one the carbon saturates quickly.
What else should I check at a change?
Fit the new O ring, check the bowl seal and make sure the auto drain is clear before putting the line back under pressure.
