Required filtration in a compact size

What is Grade D Breathing Air?

The Occupational Safety and Health Administration (OSHA) standard 1910.134 requires employers to provide employees using atmosphere-supplying respirators (compressed air) with breathing gases of high purity. This is further defined by the American National Standards Institute (ANSI) specification G-7.1-1989 which details proper levels of Oxygen, Hydrocarbon, CO, and CO2.

Wilkerson's 3 stage filtration system has been used in these applications for many years and can help meet this standard for worker safety.*

Features of Filtration
  • High flow in compact sizes
  • 3 stages of filtration
  • Visual maintenance indicator on 2nd stage
    turns red when maintenance is required
  • Designed for quick and easy assembly
    and maintenance

*This 3 stage filtration system is only a portion of a complete Grade D breathing air system and should be used as such. Using these products does not guarantee Grade D breathing air. Quality of downstream air is dependent on the supply air. CO levels should be continuously monitored with audible and visual alarms. Air quality should be checked regularly to confirm Grade D specifications per OSHA 29CFR1910.134.

set to 125psi, and fittings compatible to the respirator
manufacturer's hose.
