SLCX710 4 3AC Revolution ATEX Long Cased Axial Fan Three Phase AC 710mm

The Elta SLCX710/4-3AC is a 710mm ATEX rated long cased axial fan from the Elta Revolution SLCX range, built for duct mounting in hazardous areas. It moves up to 23980 m³/h at free air and still delivers 15678 m³/h at 300 Pa, driven by a 3.0 kW 4 pole three phase motor running at 1410 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 23980 m³/h Fixed Speed What it is best used forThe largest SLCX, for the highest volume duties: whole building ventilation of large classified process halls, sewage and sludge treatment buildings, and large chemical or battery storage areas. It moves 23980 m³/h free air and 15678 m³/h at 300 Pa.At 71 dB(A) at the outlet and 70 kg, plan for attenuation and robust supports. If you need less volume, the Elta SLCX630/4-3AC uses the same 3 kW motor in a smaller casing. 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 SLC710/4A-3AC 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 gives the most air in the range, about 23% more than the Elta SLCX630/4-3AC at free air, and reaches 300 Pa where the 630 stops at 250 Pa. Matching flanges for 710mm are not stocked online, so ask us.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 795mm flange using the 16 holes of 12mm diameter on a 770mm 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 061B-0710 available to order, ask us Elta ancillary pack APK710/004 available to order, ask us. Its controller is not ATEX rated and must be mounted outside the hazardous area. Elta AV mounts 062-004 available to order, ask us Elta impeller side guard 078C-0710-C available to order, ask us.
