Single phase, single speed, air over, PSC induction motors for centrifugal blowers for fan coil units. With additional autotransformer a range of up to 7 speeds is attainable. Shafts have 10 mm diameter to reduce friction losses at start-up; they are supported by self-aligning sleeve bearings kept in place by special spiral springs which guarantee optimum alignment between bearings and shaft; the lubricant reserve of the bearings guarantees long, maintenance free, silent operation. Fan wheels having[...]

Single phase, 4 pole, shaded pole motors, 220-240V, 50-60 Hz, 1300 r.p.m. suitable for operation in all positions. Motors are available both in closed (IP32 or in open (IP22) construction; end shields are in die cast aluminium alloy; the carbon steel shafts are supported by self aligning permanently lubricated sintered sleeve bearings with lubricant reservoir. Insulation is class B suitable for operation with ambient temperatures from -30° to +43°C. The standard version is equipped with two single[...]

External rotor axial fans offer characteristics in line with the most demanding operation requirements. The range includes a series of models with impeller diameters from 300 to 550 mm with 4 and/or 6 pole motors, single phase, 230V/50-60Hz, or three phase 230/400V50-60Hz both in sucking and blowing versions, air flows range from 1500 to 7700 m³/h approx. The characteristics of external rotor motors allow minimum axial dimensions while granting optimum performance in terms of air flow, head and[...]
