The AlorAir VentirMax 570SD brings the digital SD controller to a 570 CFM stainless fan, for crawl spaces up to 950ft² as AlorAir rates it. Program it to ventilate on humidity, temperature, a timed cycle or any combination.
The fan starts when either trigger is exceeded, runs at one of five airflow levels, and returns to its settings after a power cut. It draws 0.52 A at 115 V and shuts down showing LO below 37°F.
Features
Programmable Digital Controller
Set a humidity trigger (1% to 99%) and a temperature trigger (37°F to 158°F); the fan starts when either is exceeded.
Timing Cycle and 5 Airflow Levels
Run the fan on a timed cycle, and step the airflow through five levels with the up and down buttons.
570 CFM Exhaust
Moves 570 CFM on 0.52 A at 115 V, rated by AlorAir for up to 950ft² of crawl space.
Memory and Cold Shutdown
Returns to its settings after a power cut, and shuts down showing LO below 37°F to protect the unit.
Stainless Steel Housing
A stainless body and IP55 rated motor made for the constant humidity of a crawl space or basement.
Stainless Insect Screen
Keeps pests larger than 0.3" out of the fan and the crawl space.
Mounts Over the Vent
The metal plate fixes over an existing foundation vent with four screws, and can be trimmed to fit the opening.

- 4 wall anchors and 4 machine screws
- Installation and user manual
Setup & Placement
Install it behind an existing foundation vent, at least 3' from a corner of the building, with the control box and motor facing into the crawl space. You need a grounded outlet within 6' and a 5/16" nut driver; add a drill with a 5/16" masonry bit for brick or block.
Remove the existing vent cover, place the fan in front of the vent and mark the four corners of the metal plate. On block or brick, drill 5/16" holes, fit the wall anchors and fix the plate with four screws; on wood framing or an existing vent, use screws and nuts. On SD models, set the humidity and temperature triggers after power-up: they ship at 50% RH and 86°F.

About AlorAir
AlorAir Solutions is based in Chino, California, and supplies dehumidifiers, ventilation fans and air scrubbers for crawl spaces, basements and restoration work. Its crawl space ventilation fans mount over an existing foundation vent and run on their own controls to move damp air out from under the house.
The VentirMax series is AlorAir's stainless steel crawl space fan line, in knob-controlled S and programmable SD versions. The VentirPro series offers knob control in aluminum-zinc or stainless housings, and the VentirPro-S2 uses two DC fans with an external probe. For a sealed, encapsulated crawl space, AlorAir's Sentinel dehumidifiers are the alternative to ventilation.
