CTHB, CTHT Venture

Range of centrifugal roof mounted fans in horizontal discharge format, designed for smoke extraction in conditions of combustion and certified F400 120 (CE marked) – except 140, 180, and 200 models. (1).  All models are suitable for air stream temperature of up to 120ºC.

Bases are manufactured from galvanised sheet steel and cowls are manufactured from spun aluminium.
All models incorporate bird-proof guard.

Available, depending on the model, with single or three-phase motors in 4, 6, 8, 4/8 or 6/12 poles.

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.
  • Speed controllable by Voltage, up to the 400 model.

Additional information

140, 180, 200 and 225 models are especially recommended for extracting smoke from the fireplaces.

In three-phase voltage, the motors can be operated in Λ/Δ connection at 380-415, which allows two-speed operation of the fans.
