SLCX400 4 3AC Revolution ATEX Long Cased Axial Fan Three Phase AC 400mm

The Elta SLCX400/4-3AC is a 400mm ATEX rated long cased axial fan from the Elta Revolution SLCX range, built for duct mounting in hazardous areas. It moves up to 4835 m³/h at free air and still delivers 3056 m³/h at 150 Pa, driven by a 0.55 kW 4 pole three phase motor running at 1390 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 4835 m³/h Fixed Speed What it is best used forModerate extract from classified rooms with a short to medium duct run: paint mixing and solvent handling rooms, battery charging rooms for forklifts and floor cleaners, chemical stores and pump rooms at water and sewage treatment works. It moves 4835 m³/h at free air and still 3938 m³/h at 100 Pa.At 150 Pa it is still a low pressure fan. If the duct includes filters, a scrubber or a long run with several bends, the Elta SLCX400/2-3AC uses the same 400mm casing and flanges but develops up to 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 SLC400 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 sits between the Elta SLCX355/4-3AC and the Elta SLCX450/4B-3AC, and shares its casing, flange drilling and accessories with the 2 pole Elta SLCX400/2-3AC, so a 400mm duct can be planned now and the fan choice made once the duty point is known.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 475mm flange using the 8 holes of 12mm diameter on a 450mm 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 400mm (061B-0400) sold each, one per duct connection Elta ancillary pack APK400/003 available to order, ask us. Its controller is not ATEX rated and must be mounted outside the hazardous area. Elta AV mounts 062-003 available to order, ask us Elta impeller side guard 078C-0400-C available to order, ask us. Guarding is not included with the fan.
