ENGWALD CORPORATION, Manufacturers of Exhaust Eliminating Systems, has after years of research and extensive testing by capable engineers, perfected various exhaust systems. These systems are the finest available and provide the ultimate in design and operating efficiency.

The ENGWALD U-50-DS, U-50-DHS, U-50-DXS, AND DXHS SERIES - Underfloor disappearing type outlet. With this model the purchase of the "Y" fitting is eliminated. The unit sits directly on the straight pipe. The contractor is required to cut a whole into the pipe and then fasten unit to pipe with either self taping screws or with strapping. This unit is generally used with transite pipe or polyvinyl coated duct.

FLOOR RECEPTACLES are of heavy cast aluminum with hinged lids, transition of heavy gage galvanized steel dipped in rust-preventing bituminous paint, with a CAST ALUMINUM HOSE SEAL AND CENTERING CASTING at the base end of transition. This design allows an adjustment of approximately plus or minus 3".

HOSE ASSEMBLY consists of a length of flexible steel, or neoprene hose, steel-cage type hose guide and tailpipe adapter with chain and hook assembly. The tailpipe adapter is designed with a slot to be used with a gas analyzer.

THE ENGWALD 3", 4", and 5" hose (depending upon system) disappear into underfloor duct when not in use.
