Elta SSDL100-1EC-R Singleflow Centrifugal Box Fan Single Phase EC - 100mm (rectangular spigots)

The Elta SSDL100-1EC-R is a 100mm Singleflow SSDL centrifugal box fan with rectangular inlet and outlet spigots and no terminal box. It moves up to 486 m³/h in free air, 403 m³/h at 200 Pa and still 259 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 3665 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 486 m³/h Speed Controllable What it is best used forSmall extract duties on 100mm duct where the fan has to sit outside the room or outside the building: a single WC or shower room, a cleaner's store, a tea point or a small office. At 100 Pa it moves 446 m³/h, which is roughly 10 air changes an hour in a room of about 45 m³.It is not the right fan for an in-room extract point on its own: for a single bathroom with a short duct a small inline or wall fan is cheaper and simpler. Like every SSDL it is not suitable for corrosive or explosive atmospheres, and the air must stay between -20°C and +60°C.Why choose this over alternativesThis is the 100mm SSDL with rectangular spigots. Pick this version when the fan connects to rectangular ductwork, so you avoid a fabricated circular to rectangular transition on each 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 SSDL100-1EC (circular spigots), Elta SSDL100-1EC-T (circular spigots with terminal box) and Elta SSDL100-1EC-RT (rectangular spigots with terminal box).The SSDL100, SSDL125 and SSDL150 share the same casing, the same 15 kg weight and the same 0.97 A motor, so the difference is spigot size and airflow.
