Nowhere else First of all, Active Ventilation was the only company I could find that offered a solar powered (PVC) roof vent fan / accelerator. The web site was easy to navigate, product specifications easy to understand, and the ordering / fulfillment process was quick and easy. The item arrived within days, neatly and safely packed. If I have any reservations, it's that the fan doesn't seem to pull much. But I'm going to trust that the CFM rating they "advertised" is accurate since everything else about them is buttoned-down.

Service was excellent and vents came in… Service was excellent and vents came in as promised. They are exactly what was needed. Haven't connected vents to them so I'll see what the sheet metal contractor says. The powdercoat has a high sheen which makes the vents reflect sunlight at certain angles. It would be better if a flat or satin finish were offered.

wrong part right treatment I ordered a vent cap to be painted. I received an unpainted one. Upon notification active ventilation immediately refunded my money. Sometimes it goes wrong but they made it right. That is my kind of company.

Custom vent for greenhouse The custom vent was exactly what we needed for the flue on the furnace vent in the greenhouse. A size that was not readily available at the stores here. Prompt manufacture and delivery was another issue. The date promised with the purchase and the delivery were anything but smooth. It finally arrived days late and the only thing that saved the job was that the installers for the repairs to the greenhouse were also delayed in finishing the job. Things worked out but not without some good antiacids along the way!!!!!

I ordered the 4” Solar Aura Solar Fan… I ordered the 4” Solar Aura Solar Fan PVC Cap finished in brown powder coat and have it mounted on my cabin roof. It seems to run without any problems this past summer; I will be using it to pull exhaust for a composting toilet next summer in addition to a solar battery fan pushing air. The fit and finish appear to be of high quality and I would highly recommend any products made by roofvents.com.
