Our desiccant dehumidifier moves air at an impressive 15,000 CFM which allows us to remove water or moisture from 20,000 square feet of an affected area in a very short time compared to other dehumidifiers. If the power is out, that's not a problem. This equipment is self-contained with its own generator. By having this portable self-contained unit on standby 24/7, it allows us to deploy to your site very quickly.
