Ventilates excess moisture -- a cause of
mold, mildew and wood rot. Increases air circulation to
fight condensation.
Constant operation helps vent radon, treated wood
off-gassing and odors that might otherwise migrate into
living areas.
The only crawl space ventilators with a
special "suitable for damp locations" ETL listing.

SPECIFICATIONS
How to determine the number of
UnderAire™ Ventilators needed:
Calculate the cubic area of the crawl space by multiplying the
length x width x height. Divide this number by 15 to determine the minimum CFM
necessary to fully ventilate the space in 15 minutes.
Example: 20' wide x 40' long x 3' high crawl space =
2,400 cubic ft.
2400 cubic ft. ÷ 15 minutes = 160 CFM of ventilation.
Pricing is based on 3 options of
fan(s) with control for the example above...
If a crawlspace requires 160 CFM's you could use...
Option 1: 2 pc V1D's providing
220 CFM's combined @ $107.50 ea. Total $215 delivered.
Option 2: 1 pc V2D providing
220 CFM's @ $149.75. Total $149.75 delivered.
Option 3: 2 pc V1's providing 220 CFM's combined @ $83.75 ea. plus (1) DH10
dehumidistat control @ $38. Total $205.50 delivered.
