Our take on the Helios MP55 Crawl Space Dehumidifier and VentirPro-S2 Ventilation Fan Comb | Crawl Space Moisture Solution

This is a two-part crawl space moisture kit: the Helios MP55 dehumidifier and the VentirPro-S2 ventilation fan. The MP55 is rated at 120 pints per day, which puts it in the heavy-duty class for sealed crawl spaces and basements. The VentirPro-S2 moves up to 240 CFM to push out humid air and pull in drier air. Together they target the two jobs a damp crawl space needs: removing moisture and exchanging stale air. Rivals at this capacity are usually sold as a dehumidifier alone, so the fan adds airflow control that a single unit does not.

Best forSealed crawl spaces and basements with persistent dampHomeowners fighting musty odors and condensationLarger footprints that need both drying and air exchangeDIY installs where a compact unit and inline fan fit
Pros
  • 120 PPD rating suits serious crawl space moisture loads
  • Fan adds up to 240 CFM of air exchange the dehumidifier alone can't do
  • Two devices cover drying and ventilation in one setup
  • Compact footprint for tight crawl space installs
Cons
  • Two units mean two power connections and more setup work
  • Fan and dehumidifier must be sized and balanced together
  • Condensate still needs a drain or pump route
  • No smart controls or app pairing mentioned for the pair

Questions and answers

How much moisture can the Helios MP55 remove?
It is rated at 120 pints per day, which is heavy-duty for a crawl space dehumidifier. That suits sealed, damp spaces rather than small closets.
What does the VentirPro-S2 fan add?
It moves up to 240 CFM, exchanging stale humid air for drier outside air. That complements the dehumidifier, which removes moisture but does not ventilate.
Do I need both units?
If the crawl space is sealed and only damp, the dehumidifier may be enough. If odors and stale air persist, the fan helps by exchanging air.
How is condensate handled?
Crawl space dehumidifiers like the MP55 collect water that must drain by gravity or a condensate pump. Plan a drain route before installing.
Where should the fan be mounted?
The VentirPro-S2 is an inline ventilation fan, so it mounts in ductwork moving air into or out of the space. Duct layout decides where it goes.
Is this kit for a basement too?
Yes. Both units work in basements as well as crawl spaces, as long as the dehumidifier's capacity matches the space's moisture load.
Where is the Helios MP55 Crawl Space Dehumidifier and VentirPro-S2 Ventilation Fan Comb | Crawl Space Moisture Solution cheapest?
At AlorairCrawlspace, for $687.06, as of our latest check.
