SLC500 4B 1AC Revolution Long Cased Axial Fan Single Phase AC 500mm

The Elta SLC500/4B-1AC is a 500mm Revolution long cased axial fan and the larger four pole 500mm model for single phase supplies. It moves up to 9266 m³/h at free air and 6336 m³/h against 150 Pa, from a 4 pole single phase AC motor running at 1440 rpm.The casing is heavy gauge steel, hot dip galvanised to BS EN ISO 1461 and suitable for external mounting, with a die cast aluminium aerofoil impeller. The motor is IP55 with sealed for life bearings, wired to an IP55 terminal box on the outside of the case. Speed control is by a 149-TC18 transformer controller. Elta give a 12 month warranty. 1 Phase AC Motor Up to 9266 m³/h Speed Controllable What it is best used forGeneral ventilation on a single phase supply at low to moderate pressure: sports halls, school halls, agricultural buildings, small warehouses and workshops, wall mounted or on short duct runs. At 9266 m³/h it gives roughly 10 air changes an hour in a space of about 925 m³.Its table stops at 150 Pa (6336 m³/h), so it is not for long ducted runs with filters or grease extract. For high pressure on single phase, the two pole 450mm SLC450/2-1AC is the alternative.Why choose this over alternativesIt is the larger motor option to the Elta SLC500/4A-1AC, which moves 7427 m³/h at free air. The 4B adds around 1840 m³/h for 0.702 kW instead of 0.483 kW, and is still quiet at 56 dB(A) at 3m.Unusually, this single phase fan out-performs the three phase Elta SLC500/4B-3AC at free air (9266 against 8075 m³/h), so there is no airflow penalty for staying on single phase at this size.Installation notes Mount at any angle, horizontally in a duct run or vertically, but make sure the fan is adequately supported: it weighs 41 kg. AV mounts and mounting feet are available from Elta. The flanges are 585mm outside diameter with 12 holes of 12mm on a 560mm PCD. Use Elta matching flanges and flexible connectors to join it to ductwork. Fit a local isolator, and protect the motor with a starter or controller that has overload protection; fuses and breakers only give short circuit protection. Do not use the isolator for day to day on and off control. Wire to diagram 152-502 for 220-240V single phase. Check rotation and airflow direction at first start and that the running current does not exceed the nameplate. Not suitable for corrosive or explosive atmospheres. Inspect and clean the impeller, motor and guards at least every 12 months.
