Tescom 44-2900 Series

TESCOM 44-2900 Series backpressure regulator is designed to be compact, extremely sensitive and for industrial gases with flows up to 20 SCFM. 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.
