The new series of the Volume flow limiter has now been extended by the nominal width 80 and 160. Thus, four dimensions are now available, D80, 100, 125 and 160. The further diameters D200 and D250 will follow in the beginning of 2007. Due to this new Volume flow limiter the usual time and cost consuming adjusting of volume flows by means of throttle elements in air and ventilation systems has become obsolete. This saves precious working-time on the building-site. In our download area you will find the new leaflet >5/9.2/EN/2, as well as the mounting and operating instruction M375QM7. Leaflet 5/9.2/EN/1 is further on valid for the nominal width D100 and D 125.
