Proper filtration is what determines the grade of a gas and for breathing air purposes proper filtration is necessary and getting adequate filtration is a big consideration when purchasing your compressor.
Nuvair represents multiple companies for gas filtration products Hankison and Norgren are some of the biggest manufacturers in the business and we carry a wide range of products from each of these vendors.
Nuvair stocks low pressure breathing air filters, condensate and oil/water separators commonly used in commercial diving practices. Whether you looking for individual filters or multiple stage packages Nuvair has your filtration in stock. You can simply order individual filters on-line or contact us to put together a breathing air package for your compressor based on your specific needs.
Not sure what size filters you need or how many filters are needed for your compressor drop us an email or phone call and we can help you with your decision.

COMMON COMPRESSED AIR CONTAMINANTS
Carbon monoxide is the most toxic contaminant in compressed air. It enters the breathing air system through the air intake, or is produced by overheating of piston type compressors. The air intake must be placed away from engine exhaust or other sources of carbon monoxide.
Air contains moisture which is drawn into the compressor and enters the air stream as a vapor. As compressed air flows through the system, it cools, causing the vapor to condense in the face piece or helmet. Moisture combines with oil and solid contaminants to form sludge, which can clog or damage system components. Water also causes rust in pipelines, and can freeze in cold weather to block air flow.
Oil is a major contaminant in systems using lubricated compressors. In reciprocating compressors, lubricating oil applied to cylinders causes small droplets by the shearing action of the piston to enter the air system as a mist. Oil mist can cause breathing discomfort, nausea and pneumonia, and create unpleasant taste and odors. Centrifugal compressors are oil free.
