Solar Attic Ventilation Unit

The VEVOR JBSF-350F is a 50W solar-powered exhaust fan designed for roof-mounted attic ventilation. It delivers 3000 CFM airflow through a 12 in blade to reduce heat and moisture buildup. The unit suits homeowners seeking automated climate control without wiring to the mains supply.

Thermostat Control and Smoke Safety

Built-in temperature and humidity sensors trigger operation automatically when conditions exceed set thresholds. A smoke sensor adds an auto-stop function for added safety during fire risk events. The aluminum alloy 1060 housing resists corrosion while the included remote allows manual adjustment from indoors.

Sustained Airflow Under Solar Load

Under continuous sunlight the 50W panel maintains the rated 3000 CFM output without thermal throttling. The 8.6 kg assembly mounts on fixed aluminum plates measuring 565 x 255 mm for stable long-term operation. Performance scales directly with available solar irradiance rather than battery reserves.

Questions about this item

How do I mount the 12 in solar attic fan on the roof and what step is often missed?

Secure the two fixed aluminum plates with the six screws and two nuts provided, then attach the battery panel support bars; the step often missed is tightening the nuts after the screws so the unit does not shift in wind.

What part will need replacement first on the JBSF-350F and when?

The remote control uses a standard coin cell that typically lasts one to two seasons; replace it when the thermostat or smoke sensor stops responding to button presses.

At what temperature does the 50 W fan hit its thermal limit and shut down during continuous operation?

The built-in thermostat stops the motor at the preset high-temperature threshold to protect the aluminum alloy housing; exact cut-off value is set at the factory and cannot be adjusted by the user.
