CA MD E RF roof fan series
Often, the air drawn in through a pipe must be conveyed outside through a roof. Axial fans bring the required pressure performance only with very high speed and the associated noise load. The CA MD E RF series offers the solution: a high pressure capacity due to a radial impeller, pipe sockets in the relevant pipe sizes and installation on the roof for direct ventilation to the outside.
Design - Shapely, modern industrial design with very compact dimensions. Housing and base plate made of pickled, phosphate-coated sheet steel with polyester paint.
Quality - Enclosed, ball-bearing 3-stage motors with thermal &overload protection ensure a long, trouble-free service life.
Safety - IP44 protection, protection class II, max. fluid temperature 50/55°C.
Installation friendly - easy horizontal installation, easy access terminal box.
Controls - By means of optional 3-step switch TRIO-CA (item no. 12869). The motors are also speed controllable by means of a stepless controller or a 5-stage transformer.
Power - The impeller unit balanced with the motor ensures high air performance with high pressure stability.
Environmentally friendly - After the life cycle, all parts can be separated by type for recycling and are labeled according to WEEE regulations.
Accessories - Extensive accessories such as. suction-side protective grills, pipe-connectors, check-flaps and speed-controllers, sensors for smoke, humidity and thermostats as well as trailing and interval relays complete the system. Mounting hardware is included.
