TESCOM™ 44-2900 Series Backpressure Gas Regulator
44-2900 Series backpressure regulator is designed to be compact, extremely sensitive and for industrial gases with flows up to 20 SCFM / 566 SLPM.
The convoluted Stainless Steel diaphragm provides excellent sensitivity and repeatability; metal-to-metal diaphragm seal minimizes the potential for leakage. Ideal for use in R & D laboratories, process systems and pilot plants.
