OLROverflow unit

OLR is a rectangular overflow unit for installation directly onto a wall. OLR consists of two sound-attenuating baffles, which are mounted on either side of the wall.

OLR can be connected by means of the accessory OLRZ which is a perforated telescope wall sleeve, which ensures excellent noise reduction. The OLRZ must be ordered seperately.
