The VentirMax 780SD is a stainless-steel crawl space exhaust fan rated at 780 CFM, with a built-in temperature and humidity controller and a memory function that restarts it automatically after power loss. Its IP55 rating and insect barrier grille suit damp basements, crawl spaces and attics up to roughly 1,300 sq ft. It runs at about 55 dBA, quieter than many open-frame crawl space fans, and the adjustable humidity setpoint spans 5% to 80% RH. It is a fit-and-forget ventilation unit rather than a whole-home dehumidifier, so it suits homeowners drying out a sealed or vented crawl space, not someone expecting true moisture removal from standing water.

Owners of AlorAir crawl space fans generally report solid airflow and dependable humidity-triggered operation, and the stainless housing holds up in damp crawl spaces. Complaints center on setup and on the controller being fussier than expected.
The VentirMax 780SD is an exhaust ventilation fan with a temperature and humidity controller. It has a stainless steel construction and an IP55 protection rating, which guards against dust, splashes, condensation and rust. A barrier grille keeps flying insects and reptiles out of the fan.
The fan moves 780 cubic feet of air per minute and runs at 55 dBA. A built-in dehumidifier reduces humidity in spaces up to 1,300 sq. ft. The controller has adjustable temperature, humidity and time settings, and the humidity range is 5% to 80% RH. A memory function starts and shuts off the fan automatically.
It is designed for spaces such as crawl spaces, basements, attics, garages and warehouses. The compact design installs in a few simple steps, and the operation panel is easy to read.
