Exhaust Fans In A Welding Shop


Exhaust fans are typically box-type fans that are most commonly used in household and industrial settings to remove harmful pollutants and chemicals from the air to ensure a more comfortable and safe working environment. Perhaps the most basic example of an exhaust fan are those that exist in bathroom showers to remove moisture from the air so that your mirrors and windows don’t fog up. But these types of fans also play a prominent role in more advanced environments as well. Welding shops, for instance, consist of airborne fumes and welding smoke that can lead to serious lung and breathing problems over time, making exhaust fans crucial for such an environment.

There are two main types of exhaust vans: venting and recirculating. The former variety includes a high-powered fan to pull in air from a given environment, which then empties the air through a duct elsewhere (typically outdoors). The recirculating type, conversely, somewhat doubles as an exhaust fan and air filter. It works by sucking air in, circulating it through the filter and blowing it back out into a specific working environment. While recirculating fans don’t improve air quality as dramatically as you might think they would – or at least not as well as venting exhaust fans – recirculating exhaust fans are generally more cost effective and easier to install than the venting type, as no duct work is typically required.

Venting and recirculating exhaust fans come in a variety of different styles, such as belt driven, direct driven, shutter mount, exterior mount and ceiling mount to meet any required setting. While exhaust fans may be more common than you may think, however, their role is perhaps none more important than in an industrial setting such as a welding shop, where removing airborne particles and harmful fumes can help maintain quality working conditions.
