Elta Slim Qube SSQU4 High Temperature Fan Three Phase AC - 710mm

The Elta Slim Qube SSQU4/4-3HT is a high temperature centrifugal box fan with a 710mm circular inlet spigot and a 298 x 940mm outlet, rated by Elta for operating temperatures up to +120°C in the duct. It moves up to 13687 m³/h at free air and 4820 m³/h at 1000 Pa, the highest pressure in Elta's performance table for this size.The 4 pole three phase IP55 TEFC motor (1437 rpm, wound for 230V delta or 400V star) sits out of the air stream and drives a free running backward curved impeller. The casing is a self supporting extruded aluminium frame with 25mm double skinned panels filled with non flammable mineral wool, the outlet position can be changed on site, and Elta give a 12 month warranty. 3 Phase AC Motor Up to 13687 m³/h Speed Controllable What it is best used forHigh volume, high pressure extract on a 710mm duct: large production kitchens, factory process lines and long duct systems with heavy filtration. It gives 13687 m³/h free air, 11131 m³/h at 500 Pa and still 4820 m³/h at 1000 Pa.It is not a smoke extract fan: the +120°C figure is a continuous in-duct running rating and the datasheet gives no smoke or fire temperature/time rating. It also needs an Eltadrive variable speed drive and a three phase motor connection. For air below 50°C a standard Elta Qube SQU box fan will do the job, and on a rooftop the Elta Clearflow CFHT roof fan avoids the need for an external roof cover.Why choose this over alternativesA standard temperature box fan such as the Elta Qube SQU is rated for an airstream up to +50°C. The Slim Qube keeps its motor out of the air stream, so grease, fumes and heat up to +120°C do not reach the windings, and the acoustically insulated double skinned panels keep the noise down inside the building. The motor and impeller lift out together for cleaning.Compared with the Elta Qube SQUHT high temperature box fans, the Slim Qube has a round 710mm inlet spigot that connects straight to circular ductwork. The Elta Slim Qube SSQU4/6-3HT uses the same 710
