Precision Compressed Air Filters - SOY Series
The precision compressed air filters offer reliable moisture and contaminant removal for compressed air systems with flow capacities from 1.2 to 88 m³/min. Through interception, inertia, diffusion, and gravity separation, these filters effectively eliminate moisture, particulates, and oil mist, ensuring clean, dry compressed air to support optimal system performance.

- C Grade: Main line filter
Positioned after the compressor and aftercooler, or before refrigerated dryers, this filter removes large volumes of liquid and solid particles ≥ 3 μm, achieving a maximum residual oil content of 5 ppm.
- T Grade: Dust removal filter
Commonly used upstream of A-grade filters or downstream of desiccant dryers, as well as for tools, machinery, motors, and cylinders. Capable of removing liquid and solid particles ≥ 1 μm, with residual oil content as low as 0.5 ppm.
- A Grade: Ultra-efficient oil removal filter
Installed upstream of desiccant dryers or downstream of refrigerated dryers, this filter captures liquid and solid particles ≥ 0.01 μm, reducing residual oil content to just 0.01 ppm. Important: A T-grade filter must be installed upstream for proper protection.
