Gas filter
Gas filter is a purification device used to remove solid particles, liquid droplets, oil mist and impurities from gas. Its core parameters include filtration accuracy, treatment flow rate, working pressure, temperature range and pressure drop. It is widely applied in high-purity gas, compressed air, chemical, medical and food industries.
