Many overseas factories only replace filter elements when blocked, ignoring daily maintenance, which leads to high system pressure drop, increased power consumption and poor air quality. Precision filter maintenance is the cheapest and most effective energy-saving measure for air compressor systems.
Daily Maintenance Tips
First, drain condensate regularly. Water and oil accumulated in the filter barrel will block the filter medium, cause pressure difference to rise rapidly, and breed oil sludge. For high-humidity areas in Southeast Asia and Europe, manual draining is required every day, or auto drains are recommended.
Second, check pressure difference gauge. Normal pressure drop is below 0.02MPa. Once it exceeds 0.05MPa, the filter element must be replaced immediately, otherwise the energy consumption will increase significantly.
Third, keep the filter housing clean. Dust accumulation on the surface will affect heat dissipation and cause secondary pollution.
Replacement Cycle Standard
C/T grade coarse filter: 3000–4000 hours；A/ACS grade fine filter: 4000–6000 hours. Harsh environments such as dust, high temperature and chemical workshops need to shorten the cycle by 30%.
Scientific maintenance can stabilize air quality, reduce power consumption by 8%–15%, and extend the service life of rear dryers and pneumatic components.
