ELGi AF (Airmate) Series downstream compressed-air filters prevent liquid and solid contaminants from entering compressed-air lines and downstream equipment. Flow range 21–6475 CFM. Remove particles from 1 down to 0.01 micron and oil aerosols from 0.1 down to 0.003 mg/m³ per ISO 8573-1:2010. Three element grades — P (coalescing pre), F (coalescing fine), C (activated carbon). A high-capacity dual-housing option saves space. Lowest-in-class pressure drop (up to 42% below competitor average) and a level-sensing drain with no air loss. ASME, CE, and CRN certified.
