These compressors provide maximum leakage control
The new triple-seal HD943 and HDL943 Oil-Free Reciprocating Gas Compressors feature a “double-distance piece” designed with three individual sets of packing, to maintain product purity and prevent oil migration. The non-lubricated (oil-free) design of these compressors includes two “distance-piece” compartments between the compressor’s cylinder and crankcase. External ports at the top and bottom of the chambers can be used for purging, pressurizing or venting. — Blackmer, Grand Rapids, Mich.
