Working conditions
Exact damper function is provided under the following conditions:
a) maximum air velocity 15 m.s
b) underpressure max. -1500 Pa or overpressure max. 500 Pa.
Dampers can be installed in arbitrary position (horizontal or vertical blade axis).
Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
Temperature in the place of installation is permitted to range from - 20°C to + 50°C.

Design with actuating mechanism
Design .44 and .54
MSD (MSD-W) is equipped by actuating mechanism Belimo BLE24(BE24-12) for 24V supply or
BLE230(BE230-12) for 230V supply. MSD with big dimensions is equipped by actuating
mechanism Schischek InMax 50.75-S (dual supply 24V or 230V).
After being connected to power supply the actuating mechanism displaces the damper blade into
operation position "OPEN" or „CLOSED“ (according to method of connection, see connection
diagram). Running time is max. 60s. If is power supply cut off, actuating mechanism is stopped
in actual position. The crank handle supplied with the actuator allows it to be operated manually.
Signaling of the damper blade positions "OPEN" and "CLOSED" is provided by means of two
integrated, invariably set terminal switches.
