Comet Fans AF Fan Series for General Industry Applications
The Comet Fans AF medium-performance fan series was developed to meet most of the cooling and ventilation requirements typical of industrial applications.
It is designed to provide the best combination of reliability, versatility, performance, quality, environmental impact and cost.
These products have characteristics that make them easily suited to the most common technical specifications and allow for considerable customisation based on specific requirements.
Solutions are available with motors from 2 to 16 poles, to favour either performance or quietness.
The AF series, based on 5 aluminium blade series and with the option of using polypropylene or fibreglass blades, offers versatility and quality that make it one of Comet Fans’ most successful products, suited to the most common ventilation requirements. It is used in more than 60 countries worldwide, including in extreme climates, environments and temperatures, and in particularly demanding duties.
The selection of AF fans is carried out using the dedicated “Comet Fans” software, based on an extensive series of tests carried out on test benches and real installations.
