Multiflow SEL630 4 3PAC Flow Inline Fan Three Phase AC 630mm

The Elta Multiflow SEL630/4-3PAC is a 630mm mixed flow inline duct fan with a three phase AC motor, moving up to 14414 m³/h in free air and 13054 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 1430 rpm on a 380 to 415V 50Hz supply, absorbing 2.75 kW with a peak current of 5.4 A at 400V. Elta list this model as supplied complete with control, with electronic controller 149-FU3004 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 14414 m³/h Speed Controllable What it is best used forLarge central extract and supply on 630mm duct with a 400V supply: factories, warehouses, sports centres, airport terminals and large commercial kitchens. It keeps 13054 m³/h at 200 Pa and 10048 m³/h at 500 Pa.At 2.75 kW and 67 dB(A) inlet at 3m it is a plant room fan: plan for silencers and anti vibration mounting near occupied areas.Why choose this over alternativesIt moves 14414 m³/h free air against 9688 m³/h for the SEL560/4-3PAC, and the next size up, the SEL710/4-3PAC, moves 20419 m³/h.The EC SEL630-3PEC on the same size moves 15167 m³/h free air for 2.117 kW with 75.4% overall efficiency, against 64.3% 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 (018-630-CLAMP) or matching flanges (061B-0630) 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.
