Casing made of galvanised sheet steel, corrosion class C3 with a copper inlet cone. Motor of the unit mounted on swing-out lid to simplify service and maintenance. KTEX fans are equipped with connection cable to connect to the ATEX rated external connection box (separate accessory) for wiring on site.
KTEX fans use single inlet radial impellers with forward-curved blades. Made of lightweight, galvanised sheet steel. Impellers dynamically balanced and paired with corresponding external rotor motors.
KTEX fans are equipped with ATEX certified, voltage controllable AC external rotor motors supported by long-life ball bearings.
KTEX fans have integrated PTC (Positive Temperature Coefficient) protective circuits with external leads for connection to a motor protection device (separate accessory). We recommend to use UEK230E motor protection, certified according to ATEX directive 2014/34/EU.
Motors of KTEX fans can be controlled by 5-step speed regulator as separate accessory. Speed regulation can be combined with timer, thermostat, hygrostat, etc. by using wide range of electrical accessories.
KTEX fans can be installed indoor in any position. To avoid vibration transfer to the duct system we recommend to install flexible connections (accessory) .
