The CL-VRC series of variable airflow regulators are terminal regulation units of the air flow used in single duct systems.
These regulators are used to control and maintain the air quantity in the variable air flow systems. The complete closure has been tested on the basis of EN 1751-EN 1886 norms.

Technical data

The CL-VRC type regulators are composed from:

•  galvanized steel casing with diameters ranging from 125 to 400mm, equivalent to the standard circular duct sizes used on the market
• regulation damper in galvanized steel with air tight seals along the width and the sides
• measuring probe for Δp to measure and maintain the air flow rate in relation to the required levels
• aligned motorized regulator for the regulation and control of the air flow

When ordering, the maximum and minimum air flow values must be indicated to correctly calibrate the regulator
