NEW CAR-T Constant Airflow Regulator with Transition

Pottorff is pleased to announce the release of our model CAR-T to complement our CAR constant airflow regulator. The CAR-T offers the CAR factory installed in a square to round or rectangular to round transition. This labor saver can help installers save time by offering an easy way to install round constant airflow regulators in a square or rectangular duct.

Model CAR-T constant airflow regulator with transition is designed to save a significant amount of money and energy by precisely controlling airflow to balance HVAC systems without the need for electrical or pneumatic controls and sensors.

CAR-T Installation Instruction
Pottorff Releases the CAR-FD Constant Airflow Regulator with Fire Damper

Our model CAR-FD can be ordered with a static or dynamic curtain type fore damper that can be installed in fore rated walls rated up to two hours. The CAR-FD fire damper employs curtain style blades for point-of-origin control of fire in static or dynamic HVAC systems.


Pottorff Releases the PI-10 Indicator Switch Package for Curtain Type Fire Dampers

Our PI-10 switch package can be used to signal an alarm or fore control system to indicate blade closure on VFD dampers. The PI-10 can be used on both static and dynamic, 1-1/2 hour rated and 3-hour rated dampers. It can be ordered factory mounted, or loose for field installation as an option on our VFD models. It can also be ordered as a stand-alone model for retrofitting installed VFD dampers that need this blade indication.

Introducing Expanded Modulating Actuator Options for Combination Fire/Smoke Dampers

The expanded Modulating Actuator options will allow our UL rated airfoil blade fire/smoke dampers to act as both life safety and air control dampers.

Pottorff is pleased to announce expanded modulating actuator options for our out-of-partition and horizontally mounted steel airfoil combination fire/smoke dampers. The Belimo FSAFB24-SR(S) modulating actuator can now be selected as an option on Pottorff's horizontally mounted  FSD-151 and FSD-152 dampers in assemblies up to 120" x 48" and on FSD-151-OP and FSD-152-OP dampers up to 36" x 24".


Pottorff Announces NEW Concealed Motor Louvers

Pottorff's NEW concealed motor louvers are designed to be used in any situation where our standard operable and combination louvers would be used, but where access to the actuator and hardware needs to be controlled or restricted.  The actuator will be concealed in the sill of the louver, and can be accessed internally (by default), externally, or both.
