1800-series

The concept of the 1800-series is in basic equal to the set-up of the 1450-series. Here however we have chosen for a different relation between width and height. Due to the relative small width of the inlet, it is very well controllable at minimum ventilation level.  At complete opening this air inlet valve has, due to the relative big height of the inlet, a higher capacity. The relative small width of the air inlet valve (533mm=21”) makes it very suitable for those situations where only little space is available.
