RRM and RRMJ manually operated flow adjustment dampers made from galvanized steel are circular dampers for balancing flowrates in the branch of a ventilation or air-conditioning network. They are fitted with a dial lever made from 

composite material for adjusting the open position of the flap and a dial locking screw. The dampers can be fitted with a motor after removing the dial lever. Most motors on the market are suitable (8 x 8mm spindle).

The ducts are connected to the damper and held in place by sealing compound, adhesive tape, or collars for dampers with no seals.

For damper couplings with seals, air-tightness up to class D (per standard NF EN 12237).

Slacken off the locking screw on the dial lever, adjust the setting, then tighten the screw.

 Sheath made from 0.75mm galvanized steel  (optional sealed coupling)

 Mounting plate + solid damper flap (other options: perforated or airtight)
