Pressure Vessels

We offer pressure vessels with capacities from less than one gallon per minute in a single bag housing to more than 12,000 gallons per minute in a multiple bag housing.

Available in 19 standard sizes in your choice of carbon steel, 304 or 316 stainless steel, or alloy construction. Each size is available in a range of port sizes and configurations. These vessels are ASME code pressure rated at either 150 PSI or 300 PSI. Multi-bag housings are also available in 100 PSI rating.

The BFN series of single bag non-code filter vessels are rated at 150PSI and offer an economical alternative for applications which do not require ASME certification.
Non-code vessels are available in four sizes in carbon steel, 304 stainless steel, or 316 stainless steel.
