SLCX355 4 3AC Revolution ATEX Long Cased Axial Fan Three Phase AC 355mm

The Elta SLCX355/4-3AC is a 355mm ATEX rated long cased axial fan from the Elta Revolution SLCX range, built for duct mounting in hazardous areas. It moves up to 3096 m³/h at free air and still delivers 2333 m³/h at 100 Pa, driven by a 0.37 kW 4 pole three phase motor running at 1360 rpm.Elta mark the SLCX to Ex h IIB+H2 T4 Gb, classified for constructional safety under the 2014/34/EU directive. The casing is heavy gauge sheet steel, roll formed, welded and dip galvanised after fabrication, and the adjustable pitch aerofoil impeller has carbon filled anti-static blades on a die cast aluminium hub. It is fixed speed, direct on line, and Elta give a 12 month warranty. 3 Phase AC Motor Up to 3096 m³/h Fixed Speed What it is best used forLow volume extract from small classified spaces on short duct runs: a solvent or flammable liquids store, a small forklift or standby battery charging room, a laboratory chemical store or a small pumping station dry well. At 3096 m³/h free air it suits rooms where only a modest air change rate is needed.It runs out of pressure at 100 Pa, so it is the wrong fan for long ductwork, filters or scrubbers. For more resistance step up to the Elta SLCX400/4-3AC (150 Pa) or the 2 pole Elta SLCX400/2-3AC (400 Pa). It is not suitable for Zone 0, and the marking is for gas atmospheres only, so ask us before specifying it for a combustible dust zone. Zone classification is the responsibility of the installer or site duty holder: check the Ex h IIB+H2 T4 Gb marking against your hazardous area classification before ordering.Why choose this over alternativesChoose the SLCX only where the area is classified as hazardous. Its Ex h IIB+H2 T4 Gb marking, anti-static impeller blades and ATEX build are what you are paying for; the standard Elta SLC355 three phase is the non-ATEX version of a similar size for ordinary ventilation and costs considerably less, but must never be used in a zoned area.It is the smallest and lightest fan in the SLCX range at 29 kg, with the lowest power draw (0.37 kW) and the quietest output at 50 dB(A) at 3m.Installation notes Electrical installation must comply with BS7671 and EN60079-0 and be carried out by competent persons. Provide a means of electrical isolation in the fixed wiring and wire to diagram 152-612 through the M20 cable entry, with the M6 earth stud bonded. The fan can be mounted at any angle. Seal all flanges with an oil and diesel resistant silicone sealant, and fix to the 425mm flange using the 8 holes of 10mm diameter on a 395mm PCD. Elta state the zone inside and outside the fan can differ by no more than one zone (for example Zone 1 inside, Zone 2 outside), except when fitted with a flexible duct connection, where there is no zone separation. It is not suitable for Zone 0. It is fixed speed, direct on line. Elta must be consulted before any speed controller or inverter is used, and the controller in the ancillary pack is not ATEX rated and must be mounted outside the hazardous area. At start up check rotation, airflow direction and that motor current does not exceed the nameplate. Inspect AV mounts and earth bonding every 6 months, and check impeller tip clearance every 26,000 hours or 3 years. You'll also need Elta matching flanges 350mm (061B-0350) sold each, one per duct connection Elta ancillary pack APK350/002 available to order, ask us. Its controller is not ATEX rated and must be mounted outside the hazardous area. Elta AV mounts 062-002 available to order, ask us Elta impeller side guard 078C-0350-C available to order, ask us. Guarding is not included with the fan.
