Transitions & flexible connectors for axial fans

Transitions & flexible connectors for axial fans

Features

A structurally certified Prefabricated modular assembly that includes a Fantech duct mounted Axial Flow Fan ranging from 560mm to 2000mm diameter. The modular assembly also includes duct transitions, flexible connectors and base frame which incorporates a mounting position for VSD if required. They can simplify installation, improve on-site productivity and save engineering, project drafting and labour costs.

  • Structurally certified modular design.
  • Certified base frame is manufactured from durable hot-dip galvanised PFC (Parallel Flange Channel).
  • Revit files with clash detection available for all models.
  • Transitions designed to optimise system performance are available as nude or with 50mm, 75mm and 100mm noise suppressing material.
  • Flexible connectors available for standard and high temperature applications.
  • Suitable for both floor or hung installations.
  • Fitted with certified lifting lugs.
  • Pre-wiring of Variable Speed Drives using EMC glands and screened cable is available.

Application

Commercial and industrial supply or exhaust air applications such as shopping centres, office buildings, hotels and carparks. Can be manufactured to handle most conditions from ambient air to hot, toxic and noxious gases.

Construction

Transitions are manufactured from galvanised sheet outer, with perforated foil inner sheet for diameters up to 710mm, and perforated galvanised inner sheet for diameters 800mm and above. All sizes are available with noise suppressing material. Standard or high temperature flexible connections are fitted to both inlet and outlet transitions.

Certified base frame is manufactured from hot-dip galvanised PFC (Parallel Flange Channel). Fan is as per AP range.
