Howell - Model 7300 Mk II - Low-Pressure Dry Air Condenser-Filter Brochure

Selected for the LHD 2-4 class, the Model 7300 Mk II low-pressure air dehydrator (LPAD) is designed to remove water vapor from low-pressure compressed air systems. The air delivered by this dehydrator is intended for use in control systems such as automatic combustion control, or in any low-pressure air system where it is desirable to eliminate moisture. Generally, the air delivered by this dehydrator is NOT of a quality adequate for use in electronics purging. Moisture removal is achieved by cooling the air stream with the ship’s chilled water. The cooled air releases moisture by condensation. The condensate is mechanically separated from the air stream and drained to the LPAD’s trap-dump valve.
