Exclusive to Tower Equipment – The Belimo pressure bypass assembly smart design provides adapted air pressure control in order to maximize occupant comfort. With embedded logic, the actuator is able to maintain proper static pressure throughout the HVAC system.
Belimo pressure bypass damper assembly, NDAP series are factory mounted with NEMPC actuator directly to a 5/8” diameter damper shaft with the universal mounting clamp. The actuator with embedded logic and differential pressure sensor automatically adjusts the damper position to maintain duct differential pressure and minimize air noise in the home when zones open and close.
The damper has a one-button automated set-up for bypass pressure control. Bypass pressure is regulated under all zoning conditions. Belimo’s damper automatically learns bypass conditions based on the system’s total static pressure and damper position.
The pressure damper assembly comes with two duct pressure sensors and tubing, for round damper sizes from 8 to 20 inches in diameter. Blades are double layered with integrated Poron® sealing gasket.
