Anyone sourcing ventilation for an industrial building knows that standerd AC units don't cut it when you're pulling fumes out of a hot roof — we've seen too many setups fail because the motors seize within a year or the bearings burn out form constant heat exposure. What we've got here is a brushless DC motor that skips the brushes entirely, so there's no mechanical wear from friction and no arcing that could ignite dust in combustible environments (usually the biggest concern for warehouses and processing plants). Each unit gets a full test run before shipment, and we hold a batch sample for retesting if you want to verify consistency against the COA.
It moves 2500 cubic meters of air per hour at under 45 decibels, which is basically a quiet hum even when the solar panel is driving it at full tilt. The aluminun alloy body and five-blade fan hold up well under constant UV exposure because the powder coating is UV-resistant — not the cheap stuff that flakes after six months. We typically see these installed in poultry barns, metal workshops, and loading docks where you can't run conduit for grid power but still need to cycle air out fast.
The solar panel is 45 watts at 15 volts DC, so it runs fan directly without an inverter or battery in most daylight hours. You can order it in white or black, and the base plate is 570 millimeters square with a 1mm thickness — standard mounting footprint that fits most existing roof openings or curb adapters. One thing we don't advertise but you should know: the brushless motor has a thermal cutoff at 85°C, so if the roof gets scorching hot and the panel overshoots votage momentarily, the fan just shuts down and restarts once it cools — no fried windings.
RoHS certified, one-year warranty, and we keep about 200 units in stock for quick dispatch, but if you need a bigger batch we can run 500 or so in about 20 working days. The MOQ is usually 10 pieces for this model, though our company can do a sample single unit at full cost if you're evaluating it for a pilot project. Each shipment includes a packing list with batch numbers and a basic inspection report — we don't automatically include the full HPLC or performence test data unless you request it, but we can email a PDF from that specific batch within 48 hours.
The MOQ for this model is 50 units for the first order. After that, we can be more flexible on repeat orders.
Standard lead time is 15-20 working days after order confirmation and deposit. For larger orders, we can schedule production to meet your timeline.
Yes, we include the RoHS compliance certificate with each shipment. If you need additional factory test reports or material certifications, just let us know.
We can offer custom colors beyond white and black, but that requires a larger MOQ. The base plate is fixed at 570×570×1mm for this model, so we can't change that without a new mold.
Store it in a dry, indoor area with temperatures between -10°C and 50°C. Keep the solar panel and fan body in their original packaging to protect the coating and blade.
