Shut-off damper with electric motor LMQ 24A or LMQ 24A-SR.

Consists of a DTU damper with a 24 V electric motor added.

1)Motor LMQ 24A is a fast-running reversing on/off-motor, suitable for extraction at working places where a fast operation is wanted.
2)Motor LMQ 24A-SR is a fast-running modulating motor, suitable for laboratory extraction where a fast change of the air flow is wanted.

The motors stops at its end position and is not damaged by blockage, although system voltage remains.

In outdoor installations, the motor must be protected from rain and direct UV radiation.

The motor is installed at a distance from the damper, which makes it easy to insulate the ventilation duct.

There is a separate assembly, measuring, balancing and maintenance instruction for this product.

Ø 80–250 fullfills pressure class C in closed position.

The torque needed for motorizing is given in the adjacent table.
