Model RPM-K. Air flow regulators with constant flow (CAV) are designed for regulating of air supply or air exhaust in ventilation systems. They can be installed in a horizontal, vertical or inclined positions. To ensure proper operation, the regulator (CAV) must be installed with horizontal position of its blade´s axis. The aerodynamic forces acting on the regulator blade due to the flow are balanced by the control device, which is set according to the 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 %.

Controller characteristics:

Nominal size: ø 80 to ø 400.
Length: L = 450.
Thickness: according to EN 1751.
External casing leakage class C.
Air flow rate: 50 to 4500 m3/h.
±15-20% for air velocities less than 4m/s.
±10% for air velocities more than 4 m/s.
Pollution, deformation of the damper body or non-steady air circulation in the all cross section of the damper can bring bigger inaccuracy.

Working conditions:

The faultless functioning of the controllers is ensured under the following conditions:
a) maximum speed of air flow 10 m/s
b) maximum pressure in the duct 1000 Pa
c) the air circulation in the whole controller section must be secured as steady on whole surface.
Controllers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
Controllers are suitable for systems without abrasive, chemical and adhesive particles.
Temperature in the place of installation is permitted to range from 0°C to + 50°C.
