SB500 CYL4 3 Biflow Bifurcated Cylindrical Axial Fan Three Phase AC 500mm

The Elta SB500-CYL4-3 is a 500mm Biflow SB bifurcated cylindrical axial fan. The motor sits in a tunnel outside the airstream, so the fan can move air at up to +200°C, or air carrying grease or dust, without that air passing over the motor. It moves up to 8280 m³/h in free air, 6912 m³/h at 100 Pa and 5472 m³/h at 150 Pa, the highest pressure in Elta's published table for this model.A 4 pole three phase AC motor (380-415V 50Hz) runs at 1415 rpm with a 750 W output and 1.65 A peak current. It is a foot mounted, totally enclosed IP55 motor with Class H insulation and sealed for life bearings. The adjustable pitch aerofoil impeller has pressure die cast aluminium blades, the steel casing is hot dip galvanised after fabrication and suitable for external mounting, and Elta give a 12 month warranty. 3 Phase AC Motor Up to 8280 m³/h Speed Controllable What it is best used forHigh volume hot or contaminated extract on 500mm duct: large commercial kitchen canopies, boiler houses, spray booths, foundry or heavy industrial process extract, and hot gas duties up to +200°C. At 100 Pa it moves 6912 m³/h.It is not rated for explosive atmospheres, so it is the wrong fan for ATEX zones, and Elta's manual also excludes corrosive atmospheres, so talk to us before using it on aggressive fumes. The motor must sit in ambient air between -20°C and +54°C even when the airstream is much hotter.Why choose this over alternativesIn the 500mm size there is also the Elta SB500-CON2-3 (2 pole three phase conical, 13691 m³/h, 80 dB(A)). As a four pole fan at 1415 rpm this one is the quieter choice at 62 dB(A) at the inlet, best on short, low resistance runs.A bifurcated fan costs more than a standard cased axial because the motor has its own tunnel and Class H insulation. If the air is clean and below +70°C, a standard cased axial fan does the job for less money; choose the Biflow when heat, grease or dust would shorten a normal motor's life. The cylindrical case has a single entry motor tunnel and is shorter than the conical model in the same size (450mm long against 710mm for the Elta SB500-CON2-3).Installation notes Mount it at any angle, adequately supported, with access for maintenance. Do not obstruct the motor tunnel, as the motor relies on ambient air through it for cooling. This cylindrical model has a single entry motor tunnel, which must face vertically upwards or horizontally to keep the motor cool. The case is 450mm long with 12 holes of 12mm on a 560mm PCD at each end, matching Elta 061B-0500 flanges. Use Elta's high temperature 063-0500-PU250 flexible connectors for hot air duties. Wire to Elta diagram 152-616. Fuses and breakers give short circuit protection only, so fit a starter with overload protection; for variable speed Elta show the fan run from an inverter. Fit a local means of isolation, check rotation and airflow direction at first start, and inspect and clean the impeller at least every 12 months.
