1 BACKWARD CURVED CENTRIFUGAL FANS Series The CHVB-CHVT range is suitable for many general ventilation applications where high system resistances are present; i.e. systems with filters, dampers etc. Range of cabinet fans, manufactured from galofficially approved to EN standard (certificate number 0370-CPD-0666) CONTINUOUS Operation vanised steel sheet with double thickness panel (sandwich type) internally lined with 17 thikness fireproof fibre-glass acoustic insulation (M0). All models incorporate direct driven backward curved centrifugal impeller with motor fitted outside of the air stream and suitable for air stream temperature up to 120ºC. Available with single phase or three phase motors in 4 poles. Motors Speed controllable by Voltage. Three phase motors are speed controllable by inverter. All the motors are IP55 Class F insulation, with Cabinet fans designed for smoke extraction in fire condition F thermal protection. Electrical supply: Single phase 230V-50Hz. (CHVB) Three phase 400V-50Hz. (CHVT) On request Three phase 230/400V-50Hz (CHVT).
