Sometimes bigger is better. The Welker F-31 Filter Dryer is supersized for high pressure, high flow applications. With a 45-lb dry weight and 1” ports, this beefy filter has the capacity to clean and dry natural gas and instrument air for critical pneumatic instruments and operations.
Dirt. Debris. Rust. Sulfur. Odorant. Water. Liquid hydrocarbons. Contaminants like these can clog, damage, flood, or even freeze your sensitive instruments if they’re not removed from your pneumatic supply. Welker offers 3 filter cartridge options for the F-31, each with its own proprietary blend of filter media for targeted contaminant removal.
Mating threads on the cap and body make servicing the filter cartridge quick and easy. Simply spin the body off to access the cartridge and spin it back on after installing a replacement.
Welker offers two options to help you watch out for water: a built-in moisture indicating eye and the standalone Welker MI-2 Moisture Indicator. Both indicators change from blue to pink when saturated for straightforward and easy visual verification. To monitor the saturation level of your filter cartridge, choose an F-31 with an indicating eye. Install the MI-2 downstream of your F-31 and pressure regulation to monitor moisture in your process.
