SX-Series
Cooling Fans
For More Information:
High-efficiency, ultra-low-noise cooling fans
The SX series is the preferred solution for applications with stringent noise requirements. These fans can reduce noise by up to 20 dBA compared with standard cooling fans.
The SX series is available in a range of diameters with different blade profiles and arrangements to meet each low-noise project’s specifications.
Low-noise fans can achieve optimum performance concerning low noise, smaller footprint, increased efficiency and low Capex.
Key features
- Diameters from 28 inches (710 mm) to 36 feet (10973 mm)
- Two blade profiles (SX, SXT) suited to compact cooling installations
- Blades manufactured from single-piece fiberglass-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
FPX-Series
Cooling Fans
For More Information:
High-efficiency, low-noise cooling fans
The FPX Series uses fixed-pitch ultra-low noise blades. As a single-piece impeller unit, they offer easy assembly and minimal maintenance, combined with an ultra-low noise design.
The FPX Series is available in a range of diameters with different blade profiles and arrangements, to meet each low-noise project’s specifications.
Low-noise fans can achieve optimum performance concerning low noise, smaller footprint, increased efficiency, and low Capex.
Key features
- Ultra-low-noise impellers with no forward swept aerofoil profile
- Diameters from 28 inches (710 mm) to 108 inches (2743 mm)
- Fixed-pitch forward swept curved blades
- Operating temperatures from -20 °C to 65 °C (-4 °F to 149 °F) as standard (extendable on request)
- Suitable for either vertical or horizontal, dry and wet, induced and forced draft configurations
