SSDL200 1EC Singleflow Centrifugal Box Fan

The Elta SSDL200-1EC is a 200mm Singleflow SSDL centrifugal box fan with long circular inlet and outlet spigots and no terminal box. It moves up to 1148 m³/h in free air, 896 m³/h at 200 Pa and still 436 m³/h at 500 Pa, the highest pressure in Elta's published table.A single phase EC external rotor motor (220-240V 50/60Hz) drives a backward curved impeller balanced to ISO1940-1, at up to 2410 rpm with an integrated commissioning control for setting speed. The 1.2mm galvanised steel casing is acoustically lined and suitable for external mounting, the IP44 motor has sealed for life bearings and runs in air from -20°C to +60°C, and Elta backs it with a 12 month warranty. 1 Phase EC Motor Up to 1148 m³/h Speed Controllable What it is best used forDucted extract or supply on 200mm duct for toilet blocks, hotel bathroom risers, classrooms, libraries and open plan offices. At 100 Pa it moves 1026 m³/h, roughly 10 air changes an hour in a space of about 100 m³, and it still delivers 896 m³/h at 200 Pa for longer duct runs with grilles and bends.It is not suitable for corrosive or explosive atmospheres, and the airstream must stay within -20°C to +60°C. Where ceiling void depth is tight, an inline mixed flow fan is more compact than a box fan.Why choose this over alternativesThis is the 200mm SSDL with circular spigots. Pick this version for standard circular ductwork when you will wire the fan without a terminal box, using the cable entry on either side. The fan, motor and performance are identical across the four versions, so the choice is only about duct shape and wiring. The same size is also available as Elta SSDL200-1EC-T (circular spigots with terminal box), Elta SSDL200-1EC-R (rectangular spigots) and Elta SSDL200-1EC-RT (rectangular spigots with terminal box).The 200 has a lower specific fan power than any smaller SSDL (0.56 W/(L/s) at 100 Pa) and 48.9% overall efficiency. The Elta SSDL250-1EC moves more at low pressure (1184 m³/h at 100 Pa against 1026), but at 500 Pa the two are level (428 against 436 m³/h), so on a high resistance system the 200 does the same job in a smaller, lighter casing.Installation notes Mount it at any angle, indoors or outside, on drop rods or Elta's SEL anti-vibration mounts (upright or inverted), make sure it is adequately supported, and leave access for maintenance. The long circular spigots take standard 200mm flexible or rigid circular duct directly; secure each joint with a clamp. There is no terminal box on this version; the supply cable enters from either side of the casing. Fit a local means of isolation as the wiring regulations require. Speed is set on the built-in commissioning potentiometer. To use an external potentiometer or a 0-10V BMS signal, remove the jumper link and connect to ST1; the commissioning setting then caps the maximum speed. Disconnect the fan before any insulation resistance testing. Elta warn this can damage the EC electronics and is not covered by warranty.
