C-GRADE:The main line filter element is mostly used in air compressors, after the rear cooler or before the refrigeration dryer. It can filter out a large amount of liquid and solid particles above 3μm, reaching the lowest residual oil content of only 5ppm.
T-GRADE:The air line filter element is mostly used for tools, machinery, motors, cylinders and other equipment and before the A-level filter or after the adsorption dryer. It can filter out 1μm liquid and solid particles, and reach the minimum residual oil content of only 5ppm.
A-GRADE:Ultra-efficient oil removal filter core, mostly used in the upstream of the adsorption dryer or the upstream of the refrigerated dryer to filter out 0.01μm liquid and solid particles, and the minimum residual oil content is only 0.001ppm.
H-GRADE:The activated carbon micro-oil mist filter element is mostly used to purify food, medicine, and breathing gas. It can filter out 0.01μm oil mist and hydrocarbons, and reach the minimum residual oil content of only 0.003ppm.
