VRRK constant air volume regulators

The regulator of the permanent air stream VRRK constitute
an independent regulation element, working without an external energy supply. It provides steady, desired volume of air, irrespectively of the changes of the pressures in the system, thanks to which it eliminates the need of counterbalancing the system.
It can be used in inflow and outflow systems, high or low pressure in the vertical or horizontal position.
The regulator works reliably from the minimum difference
of pressures, which depends on the velocity of the air
(which is defined by the diagram), to the maximum difference
of pressures equal to 1000[Pa].
