Application

The SEM-AL ventilators have found application in HVAC air handling units; they are also used for cooling of switchboxes, electric modules, elements of machinery, as air supply in industrial processes, for air blasting in boilers of central heatitng installations, etc.

Construction

A radial, low-pressure, directly-driven ventilator, designed for ventilating rooms in which the level of dust is low. The welded rotor, provided with forward-tilted blades is made of galvanized steel sheet. Wleded housing is made of galvanized steel sheet. The entire device is painted black (RAL 9005). The ventilators are designed for transporting non-aggressive and non-explosive gases. As a standard, the SEM fans are manufactured in a LG configuration with a protective mesh at the inlet.

On customer’s request, the equipment can be supplied (after prior agreement) in any color from the RAL palette, with or without a cable box on the housing, with a power cable, with a strangler at the air inlet or with a non-standard outlet flange.

Electric motor

Asynchronous single-phase 220-240V, 50Hz with a capacitor. Insulation class B; degree of protection IP 44. The motor is provided with a thermal fuse protecting it against overload. The motors are adapted for rotational speed control.
