RM-ME dual flowrate Ø 125





The RM-ME dual-actuator self-regulating motorized damper for offices is used to modulate ventilation in full or trickle mode as determined by a valve operated by an electric motor.

In the closed position (power off), a solid-plate damper fitted with a Ø80mm or Ø100mm regulator controls the trickle flowrate.

In the open position (power on), a flow regulator upstream of the damper controls the nominal flow rate.

The flow regulators provide a predetermined airflow in a pressure range of 50–250Pa for the minimum flow and 60–250Pa for the maximum flow.

The damper is adaptable to all types of circular ducting from 125–200mm diameter. It must be kept easily accessible for maintenance.

The ducts are fitted directly onto the metal connection pieces, without encroaching on the plastic section of the damper. The assembly is made airtight with sealing compound, adhesive tape, or collars, depending on the type of duct.

Observe the airflow direction indication on the damper. 

 Body + flap made from class M1 plastic
 Galvanized steel connection pieces
 Electric motor connection block (for flap opening and closing)

 Connecting cable (approx. 20cm long)

 Flow regulator in damper governing the trickle flowrate
 Flow regulator upstream of damper governing the full flowrate		  

Connect the cable to a nearby junction box.

For safety protection, provide a 1A phase + neutral circuit breaker.

Before undertaking any work on the dampers, isolate them electrically at the main switchboard.




RM-ME dual-flowrate dampers can be ordered for the flowrates listed in the table opposite.
