Sullair 425 AF Tier 4 Portable Air Compressor

Sullair 425 AF 100psi
Tier 4 Rotary Screw Air Compressor

 

The Sullair 425 AF iT4 delivers 425 cfm at 100 psig or 12.0 m3/min at 7 bar of aftercooled and filtered compressed air that meets or exceeds ISO 8573-1: Class 1.7.1 quality standards.

The AF System consists of a specially designed Sullair portable compressor with a built-in high-capacity, low-approach aftercooler, a water-condensate trap and a highly efficient contaminant removal system.

The contaminant removal system includes primary and secondary filters with condensate traps. The primary filter is a coalescing type filter which captures and removes particles down to 1.0 micron and larger in diameter, and maximum remaining aerosol content at 0.5 PPM. The secondary filter is a high efficiency coalescing type which removes particulate to 0.01 micron and larger in diameter, and maximum aerosol content of 0.01 PPM.
