Filter Vessels

M Series Vessels are designed to provide flow rates to 4,100 gpm to meet a broad range of liquid and compressed air and gas applications.

The M Series Filter Vessels are built in accordance with ASME Boiler and Pressure Vessel Code, and are available in 150 psi and 300 psi designs. M Series Vessels are also available in non-code design and construction, which parallel code standards. Designed for minimum pressure drop, these vessels are available in carbon steel, 304 and 316 stainless steel construction with 316 steel internals. They feature swingbolts with eyenuts for reduced service time, and BUNA-N O-ring seals for positive sealing.

Alternate O-ring materials are available for temperatures up to 500 F. Mechanical coverlifts are standard on all models.
