Comet Fans AF Fan Series for Oil & Gas Applications
Comet Fans AF series fans are designed to ensure reliable and efficient cooling and ventilation in Oil & Gas applications, even in environments characterised by critical operating conditions.
Thanks to their robust construction and the use of highly resistant materials, these fans deliver high performance in contexts requiring maximum safety, durability and efficiency. Designed to comply with the most stringent industry regulations, they ensure optimal operation even in potentially explosive atmospheres, corrosive environments and extreme temperatures, typical of refineries, petrochemical plants and offshore platforms.
The AF range is highly versatile and customisable, with motor options from 2 to 8 poles to suit the specific requirements of each project. Aerodynamic optimisation maximises energy efficiency while also reducing noise levels.
Manufactured with aluminium blades and also available in polypropylene or fibreglass for greater corrosion resistance, these fans represent a reliable solution for complex industrial applications. Deployed in over 60 countries, they demonstrate their effectiveness in extreme environments and challenging operating scenarios.
To select the most suitable model, Comet Fans provides a dedicated software tool that, through an extensive range of tests and simulations, makes it possible to identify the optimal configuration based on the plant specifications.
