The AlorAir VentirPro 720S is the highest-airflow VentirPro in stainless steel, exhausting 720 CFM through a foundation vent for crawl spaces of 5,600ft³ to 7,400ft³. It is built for large, persistently damp spaces.
It draws 0.7 A at 115 V, runs on its humidistat knob and pauses in freezing weather. The stainless housing, IP55 motor and stainless insect mesh are made for years in a wet crawl space.
Features
Stainless Steel Housing
A stainless steel body for long service in wet crawl spaces and basements, where plain steel would rust.
720 CFM Exhaust
Moves 720 CFM out of the crawl space, sized by AlorAir for 5,600ft³ to 7,400ft³. Draws 0.7 A at 115 V.
Humidistat Control
Turn the knob to a humidity level between 10% and 80% RH; the fan runs only while the crawl space is above it.
Freeze Protection Thermostat
The fan won't run below 35°F outdoors, and restarts as it warms to near 50°F.
IP55 Rated Motor
Sealed against dust and water jets for a damp crawl space, with overload protection.
Stainless Insect Mesh
Blocks crawling pests with bodies larger than 0.14" from entering the fan and the house.
Mounts Over the Vent
A metal mounting plate fixes over an existing foundation vent with four screws; it can be trimmed to fit.

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, hold the fan over the opening and mark the four corners of the mounting plate. On block or brick, drill 5/16" holes, fit the wall anchors and screw the plate on; on wood framing or an existing vent frame, use screws, washers and nuts. If the plate needs trimming to fit, keep clear of the power cord.

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 VentirPro series is AlorAir's knob-controlled crawl space fan line. The VentirMax series adds stainless steel housings as standard, with a digital programmable controller on the SD models, and the VentirPro-S2 uses two DC fans with a digital controller and an external probe. For a sealed, encapsulated crawl space, AlorAir's Sentinel dehumidifiers are the alternative to ventilation.
