Multi-Stage Air Filtration Direct Driven Screw Compressor JF-30A
Product Overview
The JF-30A is a complete clean air solution combining a 22kw/30HP direct driven screw air compressor with an integrated 4-stage filtration system. This system delivers compressed air meeting ISO 8573-1 Class 1 standards — achieving oil-free quality air (residual oil <0.01 mg/m³) using an oil-injected compressor with advanced downstream filtration, providing the clean air benefits without the high capital cost of oil-free compressor technology.
4-Stage Filtration System
Stage 1 - Water Separator: High-efficiency centrifugal water separator with automatic float drain removes bulk liquid water and oil-water emulsion immediately after the aftercooler. Protects downstream filters from liquid loading.
Stage 2 - Coalescing Filter (1 micron / 0.1 ppm): Borosilicate glass fiber coalescing element removes oil aerosols and fine particulate down to 1 micron. Reduces residual oil content to 0.1 mg/m³ (0.1 ppm). Differential pressure gauge indicates element condition.
Stage 3 - Coalescing Filter (0.01 micron / 0.01 ppm): Ultra-fine coalescing element removes oil aerosols and solid particles down to 0.01 micron. Reduces residual oil content to less than 0.01 mg/m³ — equivalent to oil-free compressor output.
Stage 4 - Activated Carbon Filter: Activated carbon adsorber tower removes oil vapor, hydrocarbons, and odors. Eliminates any remaining oil taste and smell. Essential for food and beverage, pharmaceutical, and electronics applications.
Additional Features
Integrated Filter Manifold: All four filtration stages mounted on a common stainless steel manifold with isolation valves. Compact design with minimal pressure drop (total ΔP <0.5 bar across all stages).
Filter Life Monitoring: Differential pressure indicators on each filter housing. Controller alerts when element replacement is needed. Prevents breakthrough contamination from saturated elements.
Automatic Condensate Management: Zero-loss electronic drains on water separator and all filter housings. Oil-water separator for environmentally compliant condensate disposal.
Built-in Dryer Bypass: Optional refrigerated air dryer can be integrated after the filtration system. 3-valve bypass allows dryer maintenance without interrupting compressed air supply.
