1 RADIAL CENTRIFUGAL FANS CBT-N Series CONTINUO Range of single inlet direct driven centrifugal fans designed for the continuous extraction of air stream up to 120ºC(1). The casings are manufactured from one piece die cast aluminium and finished with a tough, grey colour, epoxy-polyester paint coating. All models incorporate radial centrifugal impellers manufactured from die cast aluminium and finished in a red colour epoxy-polyester paint finish. Fitted with 2 poles motors (1) CSB Models: up to 70ºC. CBT-40, 60N, 80N, 100N and 130N models Motors All motors are IP55 class F(1), with ball bearings greased for life. Electrical supply: Single phase 230V-50Hz. Three phase 230/400V-50Hz. (See characteristics chart). (1) CSB and CST Models: IP44 and Class B. CBT-125, 160 and 170 models Tough casing design Radial centrifugal impeller Additional Information The scroll can be orientated (1) in 7 different positions as per the table below. Standard supplied position: LG270. (1) CSB and CST Models: only can be supplied in LG270 position. On request Fan fitted with 2-speed motor. Motor with thermal protector PTC.
