Costant air-flow rate units

Back to Regulation

The AT-KVR-R are round air flow regulation units made in PVC, with fire class M1. They are used to supply a constant air flow regardless of the pressure variation in the air duct. Due to the simple mechanical regulation, power supply is not required.
