PSMB
Pneumatic Bypass Terminal
Titus model SMB room bypass terminals vary the volume of air supplied to the room. They do this by diverting 0 to 100% of the air through a bypass opening and into the system return. While the room air supply varies, the fan operates at constant volume. Because the Titus bypass terminal is an inherently low-pressure drop design with no restrictions inserted for control purposes, it is possible to design around it a system with a low overall pressure drop. The end result is a simple, inexpensive system with a moderate horsepower requirement, eventhough the fan runs at constant volume.
FEATURES AND BENEFITS
  • Model PSMB room bypass terminals vary the volume of air supplied to the room by diverting 0 to 100% the air through a bypass opening and into the system return, while the room air supply varies, the supply fan operates at constant volume
  • Durable rubber seal on outlet and bypass opening which the diverter plate closes against
  • The pneumatic actuator is an integral part of the bypass terminal, An actuator spring range of 8 to 13 psi is standard
  • Heavy gauge steel housing
  • Dual density insulation is coated to prevent air erosion
  • Meets requirements of NFPA 90A, and UL181
  • Diverter plate rides on heavy-duty self lubricating bearings
