APM

Description

The APM pressure relief damper is designed to protect ventilation systems and technical rooms against accidental overpressure. Operating automatically by means of an adjustable counterweight, it relieves excess air when a preset pressure level is reached, ensuring the safety of industrial and commercial HVAC installations.

Its adjustable counterweight system allows precise setting of the opening pressure to suit the specific requirements of each installation.

The APM pressure relief damper operates as an HVAC safety relief valve without any power supply or actuator. It is particularly well suited to applications requiring passive pressure control in ventilation systems, air handling units (AHUs), technical rooms, and industrial process installations.
