Walmec North America offers compressed air filters that can remove liquid, oil, moisture and contaminates down to 5 microns, as well as oil and vapor removal filters with ratings of 0.01 micron. Both types of filters are designed to work most effectively when installed at or near the point of use.
A 5-micron, two-stage filtration system is available with flow ranges of 15 to 250 scfm and pressure ratings of up to 250 psi. The first-stage filter removes all liquids and particles of dirt, dust, rust and scale, and the second-stage filter removes remaining moisture, contaminants and particles down to 5 microns. An automatic float drain under the second-stage filter opens and expels all collected liquids when an ounce or more is present. The system is fully automatic with no continuous air loss.
The 0.01-micron SuperStar filter is a four-stage filtration system that is available with flow ranges of 50, 75 or 100 scfm and pressure ratings of up to 250 psi. It uses the same first- and second-stage filters to remove the contaminants down to 5 microns. Then its third- and fourth-stage filters remove any remaining particles down to 0.01 microns and absorb any remaining vapors.
The filters are suited for a variety of applications, including surface preparation, paint spraying, powder coating, air-powered tools and pneumatically operated equipment.
