BVAVD-LD

The BVAVd-LD is an electronically variable/constant flow device with a built-in silencer. The unique design of the unit means that no straight duct is necessary before the unit, thus allowing it to be fitted immediately after a bend or union piece. The BVAVd-LD is available in supply air and exhaust air versions.

BVAVd-LD is based on our well-tried air flow device with actuator eFLOW, with regulator, pressure sensor and display. The regulator has a wider working range that allows you to choose a low min. air flow. The display shows current air flow, but also max. and min. air flow settings, actual value output etc. Max. and min. settings can be made directly on the actuator with built-in potentiometers. BVAVd-LD can be used for variable air flow with 2-10V alt. 0-10V control signal or for constant air flow.

BVAVd-LD is provided with a built-in silencer. This provides several advantages that simplify both project planning and installation. The silencer part is fitted internally with a baffle and a cleanable, type approved surface layer Protec®
