ERVC Circular variable air flow regulators with servomotor LMV-D3MP
Description
These regulators are used to control and maintain the amount of air in VAV systems.
Notes
For correct pressure readings and for a flow rate tolerance of 5%, a straight duct with a length equal to 2/3 times the regulator diameter must be provided upstream. Otherwise, the air flow rate may vary between 10% and 20% from the calibrated value.
Characteristics
-Galvanised steel sheet casing;
-Dynamic Δp probe to measure and maintain the air flow rate according to the room demand;
-Galvanised steel damper with sealing gaskets;
-Operating range between 20 and 1500 Pa;
-Flow rate adjustment and control by means of a linearised motor controller;
-Self-generated and radiated noise tests according to the EN ISO 3741 Standard;
-Damper tightness test performed according to the EN 1751 Standard.
