In the industrial sector, compressed air powers numerous processes across various industries. Maintaining high-quality compressed air is crucial because it directly affects operational efficiency, product quality, and the longevity of equipment. Exposure to aggressive environments, such as oils, acids, and fast-moving particles, can weaken filter elements and compromise a compressed air system. When this happens, the filter has effectively done its job and needs replacing. Even unused filter elements can deteriorate over time due to atmospheric conditions.
Differential pressure gauges (DPG’s) on filter housings measure the pressure difference between the inlet and outlet, indicating when an element is blocked and requires replacement. If the pressure drop exceeds 350 mbar, it’s time to replace the element. However, DPG’s do not always reliably indicate an element’s condition, as they might not detect issues like holes in the element, improper fitting, or a loose filter.
The most reliable way to ensure a filtration system operates optimally is to regularly replace the elements. To maintain the integrity of your filter system and protect downstream processes and equipment, change elements annually or every 2,000 hours of operation as a preventative maintenance measure. For activated carbon filters, we recommend replacing them every six months or when oil odour is detected.
