DBS Series

The DBS series breathing air purifier from Gardner Denver will provide the clean, dry air necessary to keep your workers safe. It is designed to be used as an addition to your plant air source by converting compressed air to breathable air for those individuals working in and around a hazardous process. At the core of the process is a heatless regenerative desiccant dryer with a fixed 10-minute dryer cycle that will deliver consistent ISO 8573-1: 2010 Class 2 outlet pressure dew point quality air.

Gardner Denver's breathing air purifiers can handle flow capacities from 15 to 940 scfm (25 to 1597nm³/h) and will remove contaminants through a six stage filtration process in order to meet OSHA, CGA, ANSI and CSA breathing air standards. The DBS series breathing air purifier

To adjust DBS capacity for conditions other than rated, use the correction factors (multipliers) for inlet air temperature and pressure shown in the capacity correction factors table.
Example:Ques. What is the capacity of a 205 scfm (348 nm³/h) model when the compressed air at the inlet is 130 psig (9 bar) and 110° F (43° C)?

Ans. 205 scfm (348 nm³/h) (rated flow from product specifications table) x 1.08 (correction factor from inlet air temperature and pressure) = 221 scfm (375 nm³/h).
