Commercial Chemical Air Filtration: Why Choosing the Right System is Critical

Chemical fumes in shops, assembly lines, workstations and similar applications must be removed and controlled for safe and lawsuit-free working conditions. To achieve that, companies will choose an industrial chemical fume filtration system which can be composed of portable fume extractors, HVAC-attached filtration units, gas or mist collection systems attached directly to machines such as laser cutters, or some combination of all of the above. The net desired result or goal is to achieve the best chemical removal possible in the room or shop, providing clean air for workers to breathe.

Commercial VOC odor removal is usually achieved with heavy duty activated carbon filtration systems, since quality activated, impregnated or blended carbon remove anywhere from 20-90% of chemical pollutants on the first pass through the filters. The first pass removal rate is an important point to consider because if you’re removing something that has a 20% removal rate on first pass, you’ll need lots of air changes or passes through the unit to get 95% or more removed, such as an ambient air cleaner, source capture laboratory fume air purifier, or HVAC filtration system that can cycle the air over and over, removing more each time. 

For machine-attached filtration, for safety reasons, it is important to remember that not just any system will do. For machine-attached filtration systems, such as laser cutters, engravers, etc, carbon filters must be much thicker, heavier, and a different type of carbon to remove 95% plus on the first pass. These filters are found in quality laser cutter fume extractors for a reason. Some companies will try to skimp and buy a standard industrial carbon air purifier, not realizing that if it is exhausting back into the work space, it is actually only removing a percentage of the fumes and further circulating the rest of the fumes, creating a hazard. This approach might save a little money on the front end, but in the long run can cost hundreds of thousands of dollars paying OSHA fines, lawsuits, increased wear and tear on equipment, degradation of materials in the room or lab, etc.
