V1 = compressed air inlet
V2 = compressed air outlet
Membrane Compressed Air Dryer VarioDry
Variable dryer capacity
Universal application, various possibilities
of pressure dew point reduction depen-
ding on airflow
Automatic pressure dew point adaptation
in varying inlet parameters
Rapid reaction rate by highly hydrophillic
membrane
Dry compressed air available immediately
Technical Features
5 types with 0.9 to 18.8 scfm, higher
capacity possible upon request
Low pressure drop < 1.45 psi
Available for various pressure dew point
reductions
Low purge air demand
Ambient temperature up to +140°F
High water vapour selectivity, no change
of O2/N2 ratio of compressed air,
therefore perfectly suitable for medical
applications
Max. operating pressure: 230 psi gauge
Construction features
Compact construction
Only corrosion resistant solid synthetic
materials are used
Free of CFC, PVC and silicone
No electrical supply required
Operates almost noiseless since mecha-
nically movable parts are not installed
Low filtration needed: no abrasion of
drying agent, no afterfilter
Integrated purge air throttle valve
Large capillary diameter
