Unit Case Styles & Materials

Bebco Model WDP and RDP Whisper Drive™ Building Pressurization Units are offered in three case styles with sprayed urethane, epoxy powder coated or custom coating options to satisfy your unique and particular applications.

Case Style IC is formed from 14 gauge seal-welded galvannealed steel material. Maximum corrosion resistance is ensured by carefully cleaning all parts after fabrication, applying a wash primer to create a finish bond and then applying a sprayed urethane or epoxy powder coat finish to all individual parts, prior to assembly. To further enhance quality, the exterior surface of the case, doors and cover plates also receive a sprayed urethane or epoxy powder coat finish, as selected at time of order! This case style is intended for use in areas with no significant exposure to coastal environments, salt spray, corrosive vapors or volatile gases and liquids.

Case Styles ES and EX are formed from 14 gauge seal-welded 304 or 316 grade stainless steel materials. Although many people may believe stainless steel material is resistant to corrosion, we know even stainless steel can oxidize or tarnish over time, especially in harsh industrial environments, so we also coat ES and EX cases with the same finish as applied to IC Case Style cases, to ensure years of durable performance in extremely corrosive environmental conditions. These case styles are specifically intended for use in areas with moderate to significant exposure to coastal environments, salt spray, corrosive vapors or volatile gases and liquids.

Case Style IC

This case style is intended for passive chemical processing and refining facilities and onshore environments.

The case, rear door, interior petitions, and motor mounting bracket of all Model WDP & RDP Units are constructed from 14 gauge urethane sprayed or epoxy powder coated galvannealed steel, while all fan venturi rings and intake stack port cover plates, along with the control enclosure cover, interior trim bezel and exterior angle flange brackets of Model WDP Units are constructed from 18 gauge urethane sprayed or epoxy powder coated galvannealed steel.

To enhance overall corrosion resistance or match the finish or color scheme of a building, IC style cases can be provided with a custom finish, using any brand, color and application method you prefer, as specified by you at time of order.

Bebco Model WDP Wall Mount Whisper Drive™ Units feature seal-welded cases that are offered in galvanneal, 304 grade stainless steel or 316 grade stainless steel sheet metal to withstand any environment you may encounter from mild to extremely corrosive atmospheres.

To further protect the cases, they are carefully cleaned, a wash primer is applied to establish coating bond, and a final coat of white urethane sprayed or epoxy powder paint is applied! Their rugged construction also ensures you’ll never hear a rattle, or need to worry about premature case failures over time. Contact a Bebco Sales Associate with any questions, and rest assured you’ll always receive prompt attentive responses to ensure we can satisfy your application properly!

Case Styles IS & IX

These case styles are intended for mild to highly corrosive chemical processing and refining facilities, coastal and offshore environments.

The case, rear door, interior petitions, and motor mounting bracket of all Model WDP & RDP Units are constructed from 14 gauge urethane sprayed or epoxy powder coated 304 or 316 grade stainless steel steel, while all fan venturi rings and intake stack port cover plates, along with the control enclosure cover, interior trim bezel and exterior angle flange brackets of Model WDP Units are constructed from 18 gauge urethane sprayed or epoxy powder coated 304 or 316 grade stainless steel steel.

To enhance overall corrosion resistance or match the finish or color scheme of a building, IS and IX style cases can be provided with a custom finish using any brand, color and application method you prefer, as specified by you at time of order!

Like their wall mount counterparts, Bebco Model RDP Remote Mount Whisper Drive™ Units also feature seal-welded cases fabricated from galvanneal, 304 grade stainless steel or 316 grade stainless steel sheet metal.
