Variable air volume controllers
RPK-S and RPK-S-I
Constant air flow regulator
Description
RPK-S is a square constant air flow regulator which is used
for exact mechanical setting of required air volume in ven-
tilation systems without need of any other energy. RPK-S
is available in two versions:
RPK-S without outside insulation.
RPK-S-I with outside 50 mm thick heat and sound insula-
tion.
RPK-S is characterized by:

Design
The RPK-S is manufactured from galvanized sheet metal
only the blade is from aluminium. All steel parts are zinc
plated, spring is made from high quality steel. Sliding
bearing is suitable for high temperatures and doesn´t re-
quire any lubrication. The cover of adjusting mechanism is
made from ABS plastic and the plastic functional parts are
from PA plastic. The outside insulation is made from 50
mm thick glass fiber material with outside steel casing.
Function
The RPK-S enables regulation of individually required
amounts of air in separate ventilation system zones. RPK-
S works in temperature from -20 to 80°C and relative hu-
midity up to 80%. Recommended air flow velocity is from
3 to 8 meters per second at pressure difference to Δp 500
Pa. Accuracy is ±5 %(±10% for outer settings).
Mounting
Regulator can be mounted to horizontal, diagonal or
vertical duct. The blade must be always horizontal. It is
necessary to pay attention to correct direction of mount-
ing, so that the air is entering the regulator according to
the arrow direction, which is located on regulator casing.
Connecting the duct and the regulator is with flanges.
After mounting, set the required air volume by turning the
working screw on the controller box.
