Note: Outlet flows shown above are maximum capacities and should not be exceeded for best performance. No outlet flow 
metering valve or flow meter is installed on the adsorber/dryer and must be provided by the user. Purge flow is metered by 
integral fixed purge orifices. Capacities are based on inlet conditions of 70°F, 100%RH, normal ambient CO

levels of approx 

350-375 ppm. Outlet concentration of CO

will be less than 1 ppm and outlet dew point better than -100°F. If your flow, 

temperature or pressure are different from above, consult factory for performance. 

Unless otherwise specified, a #32 orifice 

set has been installed as standard.
