Turboflow TF630 Contra Rotating Axial Flow Fan Single Phase AC 630mm

The Elta Turboflow TF630/4-1AC is a 630mm two stage contra-rotating axial flow fan for higher pressure duct systems. It moves up to 16560 m³/h in free air and the Elta datasheet shows it still delivering 10163 m³/h at 400 Pa, all inside a compact cased unit.Both motors are airstream rated single phase induction motors with sealed for life bearings, wired through a weatherproofed cable to an IP55 terminal box on the outside of the casing. The casing is heavy gauge steel, hot dip galvanised, it suits internal or external installation and carries a 12 month Elta warranty. 1 Phase AC Motor Up to 16560 m³/h Speed Controllable What it is best used forThe biggest single phase Turboflow, for 630mm duct systems in factories, warehouses, sports centres and large plant rooms where only a single phase supply is available. It moves 16560 m³/h in free air and about 13766 m³/h at 200 Pa.It is not suitable for corrosive or explosive atmospheres, and at 69 dB(A) inlet at 3m it is not a quiet fan, so noise sensitive areas will need Elta flanged silencers. If speed control is needed in an ambient above 50°C, run it at fixed speed or look at a three phase model.Why choose this over alternativesTwo contra-rotating impellers in series let the TF630 develop far more pressure than a single stage cased axial of the same 630mm diameter, without moving up to a bulkier centrifugal box. The impellers are adjustable pitch aerofoils in pressure die cast aluminium, and Elta quote around 7% better efficiency from the increased blade chord and twist.If the duty is lower, the Elta TF560 moves up to 10577 m³/h and is rated to 400 Pa on a smaller 560mm duct, drawing 6.17 A rather than 11.40 A. Three phase versions of the Turboflow range are also made, so ask us if a three phase supply is available.Installation notes The fan can be mounted at any angle. Make sure it is adequately supported and leave easy access to the casing and the IP55 terminal box for maintenance. Wire to Elta diagram 152-510. Fit a means of electrical isolation, and Elta recommend a starter with overload protection because fuses and breakers only give short circuit protection. Locate the discharge so exhaust air cannot be drawn back through the open flue of a gas or other fuel burning appliance. At first start up check that both impellers turn the right way, the airflow direction is correct and the current does not exceed the nameplate rating. Inspect and clean the motor, blades and guards at least once every 12 months. Bearings are sealed for life. You'll also need Elta matching flanges 630mm (061B-0630) for bolting the fan to flanged ductwork, sold each. A speed controller for the TF630/4-1AC is not listed in the Elta accessory table, so ask us before ordering one. Elta flexible connector 063-0630-MAN200 and AV mounts 062-003 to stop vibration reaching the ductwork, available to order, ask us. Elta ancillary pack APK630SI/003 (flexible connections, matching flanges, AV mounts and mounting feet) available to order, ask us.
