AC Infinity CLOUDLINE H4 Humidity-Proof Inline Duct Fan
The CLOUDLINE H4 is the humidity-proof version of AC Infinity's 4-inch inline duct fan, built with IP65-level sealing so it can keep running in a damp basement, an outdoor equipment cabinet, or any enclosure where condensation is a real risk instead of a theoretical one. A dial-style speed controller sets fan speed manually.
It shares the same mixed-flow impeller and dual ball bearing construction as the rest of the CLOUDLINE line, rated for 67,000 hours of service, and runs from a standard 100-240V AC supply.
