Device for adjusting an air volume flow

Abstract

A device for adjusting an air volume flow, in particular in an air distribution network, has a central air channel which can be flowed through and a throttle which is arranged in the central air channel. A size of a cross section of the air channel which can be flowed through can be changed by a throttle, wherein the throttle has an adjustment mechanism for changing the cross section which can be flowed through. The device has in addition to the throttle a central flow element which is arranged in the air channel and which has a cover, the circumference of which increases in the direction away from the throttle. The adjustment mechanism can be activated with the device being mounted in a wall opening. This enables an optimum fine adjustment of the device.
