"ZEROIL HUNTER" high pressure breathing air purifiers offers complete protection against carbon monoxide (CO) and carbon dioxide (Co2). Easy installation, operation and maintenance with simple in-line Connections. Integral safety devices Provision is made for air quality sampling. Two main stages of air treatment each with specific functions

Stage 1 Grade ZH-AA - High efficiency coalescing filter
Stage 2 is a composite filter cartridge, with five individual processes.

A molecular sieve for the adsorption of water vapour and carbon dioxide (CO2). A bed of activated carbon for the absorption of oil vapour and odours. A catalyst bed for the oxidation of carbon monoxide (CO) to carbon dioxide (CO2) by chemisorptions and catalysis. A further molecular sieve for the removal of water vapour and reduction of carbon dioxide levels. A dust retention stage incorporating stainless steel support grids to ensure cartridge integrity.
