LBebco Whisper Drive™ Pressurization Unit Rigid Pipe Stacks

In an extremely unique application, this Emergency Deluge Fire Pump Engine Building is equipped with an oversized Bebco Model WDP Wall Mount Whisper Drive™ Building Pressurization Unit. As shown, the Unit is fed by a free-standing Bebco Model RPSK Rigid Pipe Stack, constructed from Schedule 20 carbon steel pipe and mounted to a detachable entryway platform, next to the front door.

The WDP Unit pressurizes the building and also provides emergency ventilation if interior gas detection units sense engine fuel or exhaust gases within the building. As shown in the inset image, the engine has a ducted exhaust, but relies on the automatic controls of the Whisper Drive™ Unit to supply its massive amount of intake air, while the WDP Unit also accomplishes pressurization and achieves the required 60 feet per minute air velocity through both doors when fully opened!

In this instance, the unique free-standing attributes of the Bebco Rigid Pipe Stack permitted this new building to be located within a densely occupied area of a refinery, without the need for the extensive space and clearances required for guy wire supports!

Bebco Rigid Pipe Stacks provide a free-standing fresh air intake for applications where guy wires are either impractical
or cannot be accommodated!

Flexible Intake Ducts

The Model FID Flexible Intake Duct provides a temporary, pliable fresh air duct connection to Bebco Model WDP or RDP Unit. Model FID is typically utilized in applications where the use of a permanent spiral or rigid pipe stack is not feasible.

When placed properly, the intake housing draws unclassified, fresh air into a Bebco Whisper Drive™ Pressurization Unit
from an unclassified area adjacent to the immediate vicinity.

Bebco provides all necessary accessories to complete your installation easily!

Bebco Whisper Drive™ Building Pressurization Unit Flexible Intake Duct

Bebco Model FID Flexible Intake Duct housings are manufactured from 304 and 316 stainless steel components, and the duct features a pliable neoprene coated polyester hose with a mechanically embedded galvanized steel helix to withstand years of exposure to harsh operating conditions and corrosive environments.

They serve to provide a source of fresh air where the use of a permanent spiral or rigid pipe stack is not feasible, and they are provided with 25 feet or custom length duct. Contact a Bebco Sales Associate for more information about custom duct lengths and housing options.

Flexible Intake Duct Applications next

Bebco Model FID Flexible Intake Ducts are typically used in both off-shore and on-shore applications to provide fresh air to portable mud or data logging stations, laboratories, wire-line control cabins and other temporary or mobile workstations.

Often, the closest source of fresh air is either to one side or the other of such portable units or sometimes below deck! Regardless of where fresh air can be obtained, a flexible intake duct provides a fast and easy means to get portable workstations up and running quickly, when downtime is not an option and seconds count!

Bebco Flexible Intake Ducts provide a fast and sure way to obtain fresh air when time is of the essence!
