Why a crawl space needs airflow

A VentirPro pulls damp air out through a foundation vent so drier outdoor air can replace it. Trapped humidity is what rots joists and beams, feeds mold and attracts termites; steady airflow also helps vent radon, off-gassing from treated wood and odors before they reach the living space.

Choose the 260, 540 or 720 by the volume of the space, from 2,400ft³ up to 7,400ft³.

Runs on humidity, stops in frost

Runs on humidity, stops in frost

Set the humidistat knob and the fan starts when relative humidity rises above your setting, then stops once the space dries. A factory-installed thermostat stops the fan below 35°F outdoors and lets it restart as it warms to about 50°F, so it stays off in freezing weather.

The humidistat does not override the freeze thermostat on cold days.

The motor is rated IP55 against dust and water, suited to a damp crawl space. A stainless steel insect mesh stops crawling pests with bodies larger than 0.14" from getting into the fan or the house.

The standard models have an aluminum-zinc housing; the S models use stainless steel for more corrosion resistance.

Got Questions?

Find answers below or contact our support team.

Which VentirPro size do I need?

AlorAir sizes them by volume: the 260 (260 CFM) for 2,400ft³ to 3,600ft³, the 540 (540 CFM) for 3,600ft³ to 5,600ft³ and the 720 (720 CFM) for 5,600ft³ to 7,400ft³. Multiply the crawl space floor area by its height to get the volume.

What is the difference between the standard and S models?

The fan, controls and airflow are the same. The standard models have an aluminum-zinc housing; the S models (260S, 540S, 720S) have a stainless steel housing.

Will it run in winter?

Not in freezing weather. The built-in thermostat stops the fan below 35°F outdoors and restarts it near 50°F.

Is it noisy?

AlorAir rates the 260 at under 40 dBA and the 540 and 720 at under 55 dBA.

Can I install it myself?

AlorAir states it must be installed by a qualified installer to local codes. The work itself is mounting a plate over the vent with four screws and plugging into a grounded outlet within 6'.
