PSMB Pneumatic Bypass Terminal

• 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 a 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

Titus External Round Retrofit Terminals can upgrade those old existing HVAC systems to current standards of energy efficiency and comfort! External round retrofit terminals are designed to easily convert the old system powered or constant volume systems to more energy-efficient variable volume systems. They may also be used in newly designed systems as air measuring devices and exhaust control valves. With Titus external round retrofit terminals, you never have to worry about a lengthy conversion process. Compact and lightweight, these units install quickly in cramped spaces, supported only by the existing ductwork. The simple cylindrical casing matches the standard round duct at both inlet and outlet. ECV Series and PECX units can be inserted in branch ducts where no control units have been before. They may also be used to replace older units or added to the inlets of existing units that are entirely or partly deactivated.

The ECV Series terminals are available from Titus with pneumatic, electric, analog electronic, or direct digital controls (DDCs). Flexibility in the application makes selecting Titus external round terminals the simple solution for any retrofit project.
