[4-Stage Air Compressor Dryer]: This complete air compressor filter dryer combines a 5-micron particulate filter, a 0.01-micron coalescing filter, and dual desiccant drying stages. The four stages progressively reduce particles, condensed water, oil aerosols, and residual moisture, delivering cleaner, drier compressed air for moisture-sensitive tools and equipment. [Multi-Stage Water, Oil & Moisture Separation]: The 5-micron air compressor filter captures larger particles and condensed moisture, while the 0.01-micron coalescing filter removes up to 99.99% of remaining water vapor and oil aerosols for finer air treatment. Two desiccant drying stages then absorb residual moisture for enhanced drying capacity. This air compressor water separator is designed for air lines that require cleaner, drier air before downstream equipment. [Regulated Air Pressure for Shop Applications]: The integrated air compressor regulator allows output pressure adjustment for different pneumatic applications, while the included 0–240 PSI pressure gauge provides clear pressure monitoring. A locking regulator knob helps prevent unintentional setting changes during spray painting, plasma cutting, automotive work, sandblasting, and pneumatic tool use. [Industrial Build & Easy Maintenance Monitoring]: Durable aluminum alloy valve bodies, metal filter bowls, and reinforced fittings are built for workshop and industrial air systems. Visible sight glasses let you check condensate and desiccant condition at a glance; the coalescing-filter service indicator signals when replacement is needed, and blue-to-pink desiccant beads indicate when the drying media should be changed. [Complete Installation Kit Included]: Comes ready for convenient setup with 1 x 1/2 NPT 4-Stage Air Compressor Dryer System, 3 x 5 Micron Filter Elements (one pre-installed), 2 x 0.01 Micron Filter Elements (one pre-installed), 9 x Desiccant Drying Media Bags for internal moisture removal, 1 x 1/2 NPT Nickel-Plated Iron Air Plug, 1 x 1/2 NPT Nickel-Plated Iron Air Coupler, 2 x 1/2 NPT Male Pipe Fittings, and 1 x Thread Seal Tape. Designed for convenient maintenance and long-term compressed air filtration system operation.
