Running costs are reduced as radial fans, together with optimised air routing, serve to maximise the installed air throughput and minimise energy consumption. The fan performs effectively against pressure in a housing that has been developed to reduce resistance to air flow to a minimum.
Despite an air path with low resistance, the fans can protect the components inside the panel to an Ingress Protection (IP) category of IP 55.
The entire range, which includes a passive vent and models that provide uninstalled air throughputs of 500, 800 and 1,000m³/h, utilises a single housing and hence a single cut-out, offering the flexibility to fit any unit to a single roof panel. What’s more, the fans with the largest air throughput incorporate electronically commutated motors to further improve efficiency.
Mounting and filter replacement is quick and easy, thanks to a number of key innovations. These include a clamping mechanism that allows the fans to be fitted from either inside or outside the enclosure; quarter-turn fixings that permit access to the filters, and a plug terminal electrical connection. With these design features it helps keep installation and maintenance costs to a minimum.
