CONSTRUCTION

The SEIHO Model PK-A and PK-AD Air Shower Nozzles are manufactured from heavy-gauge aluminum. The overall heavy-duty construction exceeds industry standards by a wide margin. The multi-directional louver body and all other components are machined to close tolerances from solid aluminum alloys, then bright polished. The flange-to-body gasket consists of two tandem felt strips for a leak-proof seal. These components comprise a unit which provides smooth movement of the louver body when adjusting its direction. The flange mounting gasket is closed-cell neoprene or felt, depending on unit size. A knurled aluminum thumb-operated airflow adjustment knob facilitates control of airflow by regulating the volume out of the exit nozzle with the precision internal damper. The internal damper is under tension by a stainless steel spring for sealing and quiet operation.
