The adsorbing ﬁlters are designed to remove vapors from the air line that cannot be removed by a coalescing ﬁlter. They produce air that is virtually free of oil and hydrocarbons as required by industries such as food processing, electronics, and instrumentation.
The ﬁlter cartridges contain activated carbon to adsorb hydrocarbon vapors and odors from alcohols, esters, and ketones. An optional extended bowl includes a higher capacity adsorbing cartridge which allows as much as 50 percent greater air ﬂow.
Series BFC70-E9 adsorbing filters have aluminum bowls and are offered with 1/4, 3/8, or 1/2 ports. Series FC380-E9 units have either polycarbonate plastic or aluminum bowls and are offered with 3/8, 1/2, or 3/4 ports.
An adsorbing ﬁlter should always be preceded by a particulate ﬁlter and a coalescing ﬁlter. Such an assembly is one of Master Pneumatic’s Clean Air Packages which will provide air with no more oil than 10 mg/m3 or 0.008 ppm.
