Use

RABR-VAV is both a CE-marked E120 smoke damper and a variable/constant flow unit. This combination of two functions takes care of both fire shielding and VAV flow control in the same damper. This saves time, space and money for installations in premises such as hotels, office and shopping complexes, where both these functions are required. RABR-VAV consists of a damper section, measurement unit, regulator and safety actuator.

 

Function

CE-marked smoke damper designed to prevent the spread of smoke at the ventilation duct’s penetration of fire classified walls/joist systems or for placement after air handling units that serve more than one fire compartment.

Demand-adjusted airflow minimises the energy consumption of fans, heating and cooling, as well as reducing filter costs. It also has an impact on duct dimensions, and in many cases the size of the entire ventilation system can be reduced. The dampers can be controlled with a 2–10 V/0–10 V signal from e.g. presence, temperature or carbon dioxide sensors. Max and min flows or a constant flow are always calibrated and verified at the factory before delivery. The regulator provides an actual value signal of 2–10 V/0–10 V depending on the flow. If the damper is to be controlled with 0–10 V, specify this in plain text when ordering. The standard factory setting is 2–10 V.
