erifyng Dual 5" IPX7 Solar Fan Kit 25W 12V 200CFM 13ft Cable

Solar ventilation kit for small enclosures

The erifyng ER_SPF_DBB kit pairs two 5-inch IPX7-rated fans with a 25-watt monocrystalline solar panel and 13-foot switch cable. Designed for wall mounting, it targets sheds, coops, greenhouses and similar spaces up to six feet square. No battery is included, so airflow rises and falls with sunlight intensity. Aluminium housings and double metal guards protect the 12-volt DC motors in harsh outdoor conditions.

Dual fans and switch cable extend placement options

Two fans allow simultaneous intake and exhaust or coverage of separate zones within the same structure. The 13-foot cable between panel and switch lets the panel sit in full sun while fans operate in shaded areas. A single push-button switch controls both units together; there is no remote, speed selector or thermostat. Mounting brackets and hardware are supplied for wall or roof installation of the panel.

Direct solar drive limits continuous output

Without energy storage, the 200 CFM combined rating is reached only under strong sun; output drops proportionally when clouds pass or the sun angle lowers. The IPX7 rating means each motor survives immersion, but the panel and wiring are not rated for submersion. The system suits daytime ventilation where intermittent airflow is acceptable; it cannot guarantee constant air exchange after dark or during extended overcast periods.
