Model WDP Whisper Drive™ Units mount through a framed cutout in the exterior wall of the room or building to be pressurized, which should be oversized by at least 0.25 inches on all sides to permit easy insertion of the Unit and provide clearance for the Interior Trim Bezel’s mounting flange on all sides of the Unit. Please also ensure the structural integrity of the wall selected is sufficient to support the unit’s weight properly, or consider the use of bracing if required.

WDP Units

Urethane Coated Galvanneal, 304 Grade or 316 Grade Stainless Steel Housing with Cast Aluminum Control Enclosure & Junction Boxes Neoprene Gaskets & Stainless-Steel Fasteners.

To meet the most demanding corrosion resistance needs, while providing a cost-effective solution, Model WDP Units are offered in 14 gauge seal-welded galvanneal, 304 grade stainless steel or 316 grade stainless steel. These self-contained configurations also contain all other components, as listed on the Material Specifications Table, including as the most notable items the control enclosure, room pressure gauge, motors and junction boxes, along with all related hardware tubing, motor cables, wiring and gaskets.

RDP Units

Urethane Coated Galvanneal, 304 Grade or 316 Grade Stainless Steel Housing with
Neoprene Gaskets & Stainless Steel Fasteners.

Model RDP Unit Housings are offered with materials identical to the WDP Housings, but as configured only feature disconnect switches, as opposed to the broader range of components in Model WDP Units. In some respects, this difference makes Model RDP Units more durable, which is appropriate since they are often located in much more remote locations than their Model WDP counterparts.

Model RDP Remote Control Stations

Cast Aluminum Control Enclosure & Aluminum Gauge with Enamel Finish in 316 Grade Stainless Steel Mounting Plate

Model RDP Remote Control Stations are offered with a cast aluminum NEMA 4 and 7 rated control enclosure, a cast aluminum room pressure indicator with an enamel finish and Lexan® lens, and a 316 grade stainless steel mounting plate, flame arrestors, tubing and fittings to mount and connect the indicator’s differential pressure ports. This Control Station is suitable and intended for indoor or outdoor use, and the room pressure indicator must be tubed to reference external atmospheric pressure or room pressure depending on the Station’s location.
