Service
DVAP units are sized for intermittent Dewar and single-cylinder withdrawal duty. For continuous high-flow service, the FWM AV Series ambient vaporizers are typically the better fit.

Rated performance
Sustained flow by run time
Flow ratings are sustained nitrogen / air ratings measured at 300 PSI with LN2 / air at 70F, listed by run time (4, 8, and 24 hour). Actual performance varies with ambient temperature, humidity, gas service, and duty cycle. Consult FWM for application-specific sizing before purchase.
