Schako VM-PRO-R. The round, mechanical controller.
Schako VM-PRO-R, mechanical constant controller, subsequently adjustable and in stock at Felderer!
Round volume flow controller Schako VM-PRO-R for extract air and supply air systems with the possibility of manual setpoint adjustment for controlling constant volume flows.
The VM-PRO-R Constant volume flow controller operates without auxiliary power and automatically. Its central, ball bearing mounted flap is moved by the air speed. The control unit with control curve, damper and spring is mounted on the outside of the galvanised sheet steel housing. The preset flow rate of the controller can be changed by subsequent adjustment. An adjustment curve attached to the housing makes this possible. A cover protects the control unit. The installation of the controller is position-independent.
- differential pressure range: 50 – 1000 Pa

operating temperature: 10 – 50 degrees
housing leakage, class C, DIN EN 1751
The controller can also be ordered as VM-PRO-R-E. With this device version, the preset volume flow rate can be adapted to changed room occupancy by means of a motor and a control signal.
The VM-PRO works on a mechanical principle and is an adjusted controller. Mechanical or manual intervention in the controller is not permitted. If a high flow rate setting is selected, the damper blade must not be closed manually. Otherwise, the control mechanism will be adjusted, resulting in a loss of control accuracy. The area of application must always be taken into account. If the permissible range of application of the VM-PRO is exceeded, this leads to mechanical overload and also to a loss of control accuracy.
