Product description Function description Features Product description The mechanical constant fl ow volumetric controller CAV-S is made of galvanized steel and works independently without requiring additional energy. The housing design is available in round or rectangular CAV-S, round Functions description The central ball-bearing fl ap 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 fl ow is set in-factory. An adjustment of the volumetric fl ow 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. CAV-S, rectangular For maintenance, service, retrofi tting, etc., inspection openings in suffi cient number and size must be provided onsite. Available connections are socket/socket, fl ange/fl ange or pipe/pipe. The constant volume fl ow controller CAV-S is suitable for supply and exhaust air fl ow control and the air volumes setpoints are step adjustable (1...10 steps). To ensure accuracy, a suffi cient fl ow route should be maintained. Attention: The CAV-S is an adjusted controller working by the mechanism of action principle. Tampering with the controller, whether manually or mechanically, is prohibited. When a high volumetric fl ow setting has been selected, the damper leaf must never be closed manually. Otherwise, the control mechanism will be changed, resulting in a loss of control accuracy. The range of application must always be complied with. If the CAV-S is used beyond its allowed range of application, this will result in mechanical overload and thus in a loss of control accuracy. We would like to point out that to clean the stainless steel design, only suitable corresponding cleaning materials must be used!
