extractionventilation230VAC

Dynamic discharge systems with roof-mounted extract fans and motorised opening function. Suitable for installation in industrial or commercial buildings. Can be used for ambient ventilation in the buildings in which it is installed. Fan: • An extremely robust structure that is able to withstand severe weather changes. • Equipment structure made of anti-corrosive galvanised sheet steel. • Designed to ensure watertightness. • 100 mm thick thermal insulation for the hatch and 60 mm for the sides. • Adapter socket (or skirting) for correct and easy installation on the roof. • Maintenance switches for actuator and fan disconnection with auxiliary contacts. • Tubular casing in sheet steel with polyester resin anti-corrosive treatment. • Cast aluminium impellers. • Models 125 with 6 or 9 blade cast aluminum impellers, with adjustable angle of inclination. Opening system: • Motorised opening arm, with encapsulated IP65 mechanism. • Supply voltage at 230 V AC 50/60 Hz. • System reinforced and guaranteed with more than 11,000 cycles. • Snow load SL 1000. • Automatic opening by external signal from the control system (fire panel, smoke detector ...). Control systems not included in the equipment. • Limit switches in both positions (open and closed). Motor: • Motors with IE3 efficiency for powers equal to or greater than 0.75 kW, except single-phase, 2-speed and 8-pole. • Class F motors with ball bearings, IP55 protection. • Three-phase 230/400 V 50 Hz (up to 4 kW) and 400/690 V 50 Hz (powers greater than 4 kW). • Working temperature: -25 ºC +50 ºC.
