Question:
Hey Jim,
Do you have some thoughts on this Dri-Eaz Studebaker AirPath? I heard that the carpet dries when you leave the job.
Thanks for your interest in the Dri-Eaz AirPath.
The speed of which the Airpath will dry a carpet varies with the cleaning method used, the carpet fiber type, and the atmospheric conditions in the structure.
More simply put:
Heavily soiled carpets that require extensive preconditioning treatments take longer to dry.
Carpets cleaned with portable machines with weak vacuum and high pressure pumps take longer to dry.
Wool carpet takes longer to dry than do synthetic fiber carpets.
Carpet cleaned in a dwelling without air conditioning when there is high humidity outside will take longer to dry.
Homes where the entire carpet as well as the upholstery is cleaned, will generate a great deal more water vapor during the evaporation process, and will take longer to dry than they might when only a living room, dining room, and a hallway or stairs are cleaned.
Carpets that have protector applied will take longer to dry.
With all of the above factors in mind, our experience has been that nylon carpet cleaned in an environment of controlled humidity (A/C in summer, as an example) with a truck mount system in good operating condition and 300 CFM or more airflow will dry in about 15 minutes in the room that the AirPath is running. If you add any of the above factors into the equation, the drying time can extend to a few hours or more even with the AirPath.

My equipment has a vacuum 16" Hg: 280 CFM with installed SOVC. I always connect
my auto pump out for my recovery tank and also a inline aqua filter to reduce
debris getting inside the recovery tank. My question is: Will the CFM decrease?
Jim, thank you for your response about the performance of Dri-Eaz Studebaker AirPath.
Your equipment specifications are such that you should be able to have carpet fairly dry if not dry when you leave the job, although you should still bear in mind the variables of "heavy preconditioning wetting", wool absorbency, the extra moisture left behind after protector application, and the environmental conditions.
In line filtration devices are a great convenience, and will help to prevent clogging in your automatic pump out. However, they do restrict airflow; the amount of which varies somewhat with design, but mostly with how often you clean the filter.
Jim
