The SKF separator filter dryer system removes water, contaminants and oil vapor from compressed air; it dries compressed air for pneumatic applications directly from a compressor’s reservoir tank or at a point of use. The 3-in-1 system incorporates a dual-cartridge design that channels air flow through a desiccant cartridge, while regeneration occurs in another cartridge. Standard units operate between 100 and 180psi and accommodate flow rates from 20 to 800 CFM. The system operates in high or low ambient temperatures without the use of a refrigerant, condensate drain line or heat exchanger.
