Multiflow SEL315 2A 1AC Flow Inline Fan Single Phase AC 315mm

The Elta Multiflow SEL315/2A-1AC is a 315mm mixed flow inline duct fan with a single phase 2 pole AC motor, moving up to 2354 m³/h in free air and 2189 m³/h against 100 Pa. A diagonal mixed flow impeller and 3D stator guide vanes give it far more pressure than an axial fan of the same diameter.The motor runs at 2819 rpm on 220 to 240V 50Hz, absorbing 0.263 kW at its best efficiency point with integral thermal overload protection, and it is wired through an integral IP44 terminal box. The casing is weatherproofed to IPX4, the fan mounts at any angle on its integral bracket, and Elta give a 12 month warranty. 1 Phase AC Motor Up to 2354 m³/h Speed Controllable What it is best used forHigh pressure ventilation on 315mm duct from a single phase supply: changing rooms, gym and squash court extract, commercial kitchens behind filtered canopies, hotel and office toilet blocks. It holds 2189 m³/h at 100 Pa and 1652 m³/h at 300 Pa.Above 350 Pa the airflow falls away sharply (540 m³/h at 400 Pa), so for higher resistance or more air choose the SEL315/2B-1AC, which still moves 2848 m³/h at 300 Pa.Why choose this over alternativesThe SEL315/2A-1AC is the standard 315mm single phase SEL: 2354 m³/h free air for 0.263 kW. The high performance SEL315/2B-1AC uses a 0.515 kW motor to reach 3510 m³/h and holds its airflow to 400 Pa, but costs more, weighs 15 kg against 8 kg and is louder. Choose the 2A where the system is under about 300 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. Elta recommend padded connection sleeves or fast clamps (018-315-CLAMP) to cut noise transmitted into the ductwork. Run the airflow in the direction marked on the casing. Wire into the integral IP44 terminal box to Elta diagram 152-540. Elta specify the 149-TC14 5 step transformer controller (4 A) for speed control; at lower steps the fan runs at 2640, 2425 and 1895 rpm. The internal thermal protection does not protect the motor if the impeller is blocked, so where that could happen fit a motor protection switch with thermal and magnetic release. Fit a means of isolation and earth the fan. 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 149-TC14 single phase 5 step transformer controller (4 A), the controller Elta specify for this fan.
