Bebco's UL-Approved Whisper Drive building pressurization units offer quiet operation
Bebco's UL-Approved Whisper Drive building pressurization units offer quiet operation, while greatly reducing the amount of make-up air used to maintain pressurization. A primary fan, controlled by a variable speed drive, maintains safe pressure when the doorway is sealed. Upon loss of safe pressure, the secondary fan engages to increase flow to meet the NFPA requirements. Wall and Remote mounted versions available. Detailed information is contained in the WDP, RDP and Accessories Technical Bulletins.
