Description

Clearflow CF Roof Mounted Discharge Centrifugal Fan

The Clearflow CF is a vertical discharge centrifugal roof fan designed for commercial plus industrial extract where you want odours and discharge air projected away from occupied areas. It combines an all metal weather resistant casing with an advanced backward curved impeller to deliver strong performance with minimal installation fuss.

Select models are available for next day delivery.

Why Clearflow CF is specified

  • Vertical discharge: helps throw exhaust air upwards to reduce nuisance odours at roof level
  • Simple roof installation: can be mounted on flat roofs plus pitched roofs up to a 30° angle
  • Space saving: roof mounting keeps plant out of internal areas where space is limited
  • Efficient centrifugal impeller: backward curved design with profiled blades to reduce losses and improve efficiency at the duty point
  • Weather focused details: wind guard fitted as standard to help reduce noise plus limit draughts entering the duct
  • Wildlife protection: bird guard fitted as standard

Range overview

  • Sizes: 5 standard sizes from 315mm to 500mm
  • Air volume flow: up to 2.66 m³/s depending on model
  • Static pressure: up to 618 Pa depending on model
  • Motor type: AC external rotor motor
  • Warranty: 12 months

Build quality and components

  • Casing: robust all metal construction manufactured from pre galvanised sheet steel for long life on exposed roof locations
  • Impeller: free running impeller with 7 backward curved fluted blades made from high performance composite material for high efficiency plus lower acoustic power
  • Maintenance access: wind guard is easily removable to support cleaning and periodic inspection

Installation notes that matter on site

  • Duct connection: the spigot sits on the underside of the unit so it can connect directly to the main duct run
  • Mounting angle: suitable for roof pitches up to 30° when installed correctly
  • Servicing: plan access for future cleaning and annual inspection

Speed control and setup

Where variable airflow is required, Clearflow CF can be paired with transformer voltage controllers to provide five speed step control. Reducing fan speed can lower energy use and also reduce the cost of conditioning replacement air.

Typical applications

  • Commercial kitchens and catering
  • Hospitals and healthcare buildings
  • Bakeries
  • Industrial plus commercial extract systems

Selection tip: choose the fan size to match your roof curb and duct diameter then confirm the duty point using the performance data for airflow and static pressure. If the project involves higher temperatures or unusual conditions, confirm limits using the installation guidance and the technical data sheet before final specification.
