VMPR/VMPQ TECHNICAL DOCUMENTATION Field of application | Useable volumetric flow ranges FIELD OF APPLICATION USEABLE VOLUMETRIC FLOW RANGES Volumetric flow controller for supply and return air systems, suitable for regulating a constant volumetric flow with the option of electrical setpoint adjustment. ATTENTION The VMPR/ VMPQ is an adjusted controller working by the mechanism of action principle. Tampering with the controller, whether manually or mechanically, are prohibited. When a high volumetric flow setting has been selected, the damper leaf must never be closed manually. Otherwise, the...

VMPR / VMPQ TECHNICAL DOCUMENTATION Function | Processing The constant volumetric flow controller VMPR/ VMPQ works independently without requiring additional energy. The central, ball-bearing flap is moved by the air current. The control unit with control cam, spring and damper is attached to the outside of the galvanised sheet steel housing. The required volumetric flow is set in-factory. An adjustment of the volumetric flow at a later stage is possible (setting cam on housing). The control unit is protected with a cover. The controller can be assembled in any assembly position. --- Operating...

VMPR / VMPQ TECHNICAL DOCUMENTATION Prior to assembly and commissioning | Installation-maintenance-service An instruction leaflet containing information on safety, transport, disposal, installation, commissioning and maintenance is enclosed with each SCHAKO product. For safety reasons, this instruction leaflet must be read under all circumstances and completely adhered to. Required distances To avoid unnecessary controller errors, the min. distances according to the following table / drawings must be observed. For combinations of several connection pieces or pieces with fire dampers or silencers,...
