BVAVd-3 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-3 can be used for variable air flow with 2-10V alt. 0-10V control signal or for constant air flow. BVAVd-3 is available with Modbus-communication as option.
