SX-Series Industrial Cooling Fans

High efficiency, ultra-low noise cooling fans

The SX series is the preferred solution for applications with stringent noise requirements and capable of reducing noise by up to 20 dB(A) compared with standard cooling fans. It is available in a wide range of diameters with different blade profiles and blade arrangement to meet the specification of each low noise project.
Low noise fans offer the possibility to achieve optimum performance with respect to low noise, smaller footprint, increased efficiency and low Capex.


Key features

  • Diameters from 28 inches (710mm) to 36 feet (10973mm)

  • Two blade profiles (SX, SXT) suited to compact cooling installations

  • Blades manufactured from single piece Fibreglass Reinforced Polyester

  • Between 3 and 8 blades fitted with forward swept curved, adjustable pitch blade profiles on an integral shaft

  • Operating temperatures from -20°C to 65°C (-4°F to 149°F) as standard (extendable on request)

  • Suitable for multiple configurations: vertical and horizontal, dry and wet, induced and forced draft

  • SXT models equipped with air seal technology

  • ATEX compliant


  • Able to handle a wide range of flows

  • Ultra-low noise

  • Optimised aerodynamic and acoustic performance in a smaller footprint

  • Maximised strength at a lower weight to reduce vibration

  • Integrated shaft eliminates concentrations of stress at the mechanical joints giving greater durability and reduced maintenance

  • Air seal technology significantly reduces backflow and increases fan efficiency

  • Safe operation within facilities requiring spark-free equipment

Range graph


The SX series is the ideal solution combining low noise emisions with optimal performance and can be applied in a wide range of applications. For example, Air Cooled Heat Exchangers, Cooling Towers and Air Cooled Condensers. The SXT is derived from the SX with a smaller diameter range and therefore is primarily intended for smaller Cooling Towers and Air Cooled Heat Exchangers.

The SXT Blade - the next generation of ultra-low noise fans

The latest SXT blade profile is our ultra-low noise solution that extends our S series of cooling fans. Ideal for cooling towers and air cooled heat exchangers the new design is both quiet and efficient.
