Equipment for controlling humidity includes large commercial-grade fans like these, which draw 2.4/2.8 amps (high/low) to move up to 1,000 cfm (2,700 fpm).
In addition to using fans to control humidity, the author runs industrial dehumidifiers. The Dri-Eaz DrizAir 1200 shown here has been in service for eight years. Its only drawback is that the filter clogs easily.
At its air intake, the Quest PowerDry 4000 employs a paper filter that can handle a large amount of dust.
Bringing the permanent HVAC system online while dust is still being created would cause equipment failure down the line. Instead, portable units such as this Quest Cool ACS 12 are used to condition the interior.
This 2-ton Movin Cool Classic Plus 26 is a portable small package unit, which contains both the evaporative and condensing coils.
The Quest Power Electric Heat EHS 31 Pro is a 31,000 Btu unit that warms a large space than the small box units do.
A 5-ton heat-pump for heating and cooling is set up on staging outside the house, and unlike the smaller units, doesn't need to be shuffled around the jobsite. Shown here is the supply duct.
