Elta SSDL200-1EC-RT Singleflow Centrifugal Box Fan Single Phase EC - 200mm (rectangular spigots and terminal box)

The Elta SSDL200-1EC-RT is a 200mm Singleflow SSDL centrifugal box fan with rectangular inlet and outlet spigots and a pre-fitted 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 rectangular spigots and terminal box. Pick this version when the fan connects to rectangular ductwork and you also want a pre-fitted terminal box for a quick, tidy electrical connection. 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 (circular spigots), Elta SSDL200-1EC-T (circular spigots with terminal box) and Elta SSDL200-1EC-R (rectangular spigots).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-RT moves more at low pressure (1184 m³/h at 100 Pa agai
