Description
The FS-CURTIS D339FE filter replacement is an activated carbon coalescing adsorber filter element designed to remove oil vapors, hydrocarbons, and odors from compressed air systems. This element helps protect dryers, valves, regulators, pneumatic controls, and other downstream equipment from contamination-related wear and performance issues.
This FS CURTIS D339FE replacement element is commonly used as an aftermarket alternative to the original SULLAIR element. Adsorber filters remove oil vapor using activated carbon and typically achieve a residual oil content of 0.003 mg/m³ or better when used with proper upstream prefiltration. They are commonly used in food and beverage processing, pharmaceutical manufacturing, instrumentation, packaging equipment, and other applications where ultra-clean compressed air is required.
