Multiflow SEL400 1PEC Flow Inline Fan Single Phase EC 400mm

The Elta Multiflow SEL400-1PEC is a 400mm mixed flow inline duct fan with a single phase EC motor, moving up to 7128 m³/h in free air and still 5864 m³/h against 500 Pa. A diagonal mixed flow impeller and 3D stator guide vanes give high pressure from a compact circular casing.The EC motor runs at 2972 rpm at its best efficiency point on single phase 230V 50Hz, absorbing 1.512 kW with a peak current of 8.8 A, and is driven by Elta's external EC motor controller 149-ECC1401 for step-less speed control. The casing is weatherproofed to IPX4 with an integral IP44 terminal box, and Elta give a 12 month warranty. 1 Phase EC Motor Up to 7128 m³/h Speed Controllable What it is best used forHigh pressure, high volume ventilation on 400mm duct where only a single phase supply is available: commercial kitchen extract, sports centres, gyms, airport and retail back of house, and central supply plant with heat recovery and filters. It holds 6678 m³/h at 200 Pa and 5864 m³/h at 500 Pa.It draws up to 8.8 A on a single phase supply and is rated at 66 dB(A) inlet, 70 dB(A) outlet at 3m, so it needs a dedicated circuit and silencers near occupied rooms.Why choose this over alternativesAgainst the AC SEL400/2-3PAC (6919 m³/h free air, 60.7% efficient), this EC model moves 7128 m³/h at 64.4% overall efficiency, with an FMEG grade of N 73.0. EC control gives smooth step-less speed adjustment from a potentiometer or 0-10V BMS signal, and lower running costs when the fan is turned down.Where three phase is not available, it is the high pressure answer on 400mm duct: the single phase AC SEL400/4-1AC falls away above 150 Pa, while this model still moves 6167 m³/h at 400 Pa.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. The EC motor is driven through Elta's external EC motor controller 149-ECC1401. Wire to Elta diagram 152-547 and take the fuse rating from the controller's own documents; speed is then set with a 149-POT-10-MI potentiometer or a 0-10V signal. Use fast clamps (018-400-CLAMP) to connect to the duct, and run the airflow in the direction marked on the casing. Fit a means of isolation and earth the fan and controller, and check the running current against the nameplate on first start. 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. You'll also need Elta EC motor controller 149-ECC1401, available to order, ask us.
