Indeed, they are. Employing a compressed air filter for your compressor machinery is key to enhancing its lifespan and reliability. These filters efficiently screen out impurities like dust, dirt, oils, bacteria and even traces of heavy metals such as lead and mercury. Without the use of air filters, contaminated air can lead to premature wear, contamination of control valves, and cause protective seals to swell, significantly reducing the operational life of your compressor and increasing energy costs.
