T791 and T891 compressors

The T791 and T891 compressors are designed for applications that require maximum leakage control when handling toxic, hazardous, and explosive gases. Each piston rod has three sets of packing that form two distinct distance pieces, which serve as barriers to the atmosphere. Since each distance piece has its own line connections that can be separately pressurized, purged, padded, and/or vented, the T-Style compressors provide a wide range of flexibility for controlling external leakage. Purge kits containing all of the accessories needed to purge each barrier are available, making the T-Style machine virtually leakproof. The T791 is a two-stage compressor with a working pressure of 615 psia (42.4 bar), while the T891 is a single-stage, 465-psia (32.1-bar) compressor. Both are double-acting machines with piston displacement just over 100 ft3/min (169.9 m3/h).
