M A X T E M P C T H B / C T H T R o o f m o u n t e d f a n s ROOF MOUNTED FANS MAX-TEMP CTHB / CTHTCentrifugal F400-120 Rated Fans Range of centrifugal roof mounted fans in hori- zontal discharge format, designed for smoke extraction in fire conditions and certified F400 120(CE marked) (1). All models are suitable for air stream temperature up to 120ºC. Bases are manufactured from galvanised sheet steel and cowls are manufactured from spun aluminium. All models incorporate bird-proof guard. Availa ble , d epe ndi ng upon the mod el, wit h s ing le or three phase motors in 4, 6, 8, 4/8 or 6/12 poles. (1) Except 140, 180 and 200 models. Motors All motors are IP55, Class F and equipped with ball bearings greased for life. Electrical supply: Single phase 230V-50Hz. Three phase 400V-50Hz . (See characteristics chart). Speed controllable by Voltage, up to the 400 model. Adjustable frecuency drive from 450 to 710. When is using a speed controller , the elec- trical installation must be equipped with a secu- rity system which allows the maximum speed of the fans in cas of fire. Additional information 140, 180, 200 and 225 models are specially recommended forextracting smoke from the fireplaces. Approved to EN12101-3 standardCertificate number0370-CPD-0347CONTINUOUS operation CONTINUOUS Smoke extract Easy to install Supports easing the installation on the roofSelf cooling system Special design in order to cool the motor and to extend the life of the assembly Backward curved centrifugal impellers T o prevent accumulation of dirt. Model s up to 400 are manufactured from galvanised steel sheet.

Technical characteristics for models with horizontal discharge CTHB/ CTHTBefore installation check that the product electrical characteristics listed on the data plate label (Voltage, power, frequency etc) match those of the intended electrical supply.
* The ratings of sound levels are pressure values measured in dB(A) at 1,5 m at 2/3 Qmax.
** Three phase speed controllers (RMT) or inverter controller (VFKB/VFTM): Three phase 400V.
