AFH Series
Comet Fans AFH Fan Series for Oil & Gas Applications
The Comet Fans AFH series high-performance axial fans are designed to ensure extremely reliable and efficient cooling and ventilation in Oil & Gas applications, even in critical and demanding environments.
Thanks to engineered design and an even more robust construction, these fans ensure superior performance under extreme operating conditions, where safety, durability and efficiency are essential requirements. Manufactured from high-strength materials and compliant with the industry’s most stringent regulations, they operate optimally even in potentially explosive atmospheres, highly corrosive environments and high temperatures, typical of refineries, petrochemical plants and offshore platforms.
The innovative blade aerodynamics, optimised through fluid dynamics simulations, maximise energy efficiency and noise levels. The AFH range offers a wide range of solutions thanks to motor options from 2 to 8 poles, adaptable to the specific requirements of each installation.
To ensure maximum mechanical and chemical resistance, the blades are available in high-strength aluminium alloy or in reinforced polypropylene or fibreglass solutions for excellent corrosion protection. AFH fans stand out for their reliability in extreme operating scenarios, making them, to all intents and purposes, the best fan in Comet’s axial series.
