Multiflow SEL710 4 3PAC Flow Inline Fan Three Phase AC 710mm

The Elta Multiflow SEL710/4-3PAC is a 710mm mixed flow inline duct fan with a three phase AC motor, moving up to 20419 m³/h in free air and 19001 m³/h against 200 Pa. A diagonal mixed flow impeller and 3D stator guide vanes give it high pressure from a compact circular casing.The 4 pole motor runs at 1410 rpm on a 380 to 415V 50Hz supply, absorbing 3.574 kW with a peak current of 7.3 A at 400V. Elta list this model as supplied complete with control, with electronic controller 149-FU4004 named in the datasheet. The casing is weatherproofed to IPX4 with an integral IP44 terminal box, and Elta give a 12 month warranty. 3 Phase AC Motor Up to 20419 m³/h Speed Controllable What it is best used forThe largest AC SEL, for very high volume systems on 710mm duct: warehouses, factories, sports halls, airport terminals and central plant. It moves 19001 m³/h at 200 Pa and still 15739 m³/h at 500 Pa.At 3.574 kW and 69 dB(A) inlet, 71 dB(A) outlet at 3m it is a plant room fan, so allow for attenuation. For lower running costs at the same size, compare the SEL710-3PEC EC model.Why choose this over alternativesIt moves 20419 m³/h free air against 14414 m³/h for the SEL630/4-3PAC, making it the largest AC SEL in Elta's datasheet.The EC SEL710-3PEC on the same size moves 20347 m³/h free air for 3.117 kW with 73.8% overall efficiency, against 66.2% for this AC model. The AC version suits sites that want a conventional 400V induction motor.Installation notes The fan can be mounted in any orientation. Slide it into the duct and fix it with the integral mounting bracket, making sure the ductwork is not strained, and connect duct to both inlet and outlet so no moving parts are accessible. Wire into the integral IP44 terminal box to Elta diagram 152-544. Elta's installation manual says the 560, 630 and 710 sizes can run direct on 400V 50Hz three phase or from a frequency converter; standard PWM converters add some motor noise. The thermal contact must be connected to an external tripping unit. The internal thermal protection does not cover a blocked impeller, so fit a motor protection switch with thermal and magnetic release, plus a means of isolation and an earth. Use fast clamps (018-710-CLAMP) or matching flanges (061B-0710) to connect to the duct, and run the airflow in the direction marked on the casing. Install indoors in a dry, condensation free space: Elta's installation manual says SEL fans must not be operated out of doors, and they are not for explosive atmospheres. Clean the impeller and casing at the recommended intervals; an upstream filter extends them.
