Specifications
Constant mechanical air volume regulators are meant for input or output air systems. Regulators can be installed in horizontal or vertical position with horizontal or vertical blade axis. The aerodynamic forces acting the list due to the flow are compensated by the control device adjusted according required flow. Adjustment of required flow is simply performed by lever with a pointer and scale. Mechanical controllers need not be connected to any external power source. The controller consists of the casing of the controller with a control blade and control device. Control device is placed inside of box with scale for adjustment of required flow. Accuracy of the scale is ± 5 %.
