Because User Experience Matters
Designed for Fleet Owners Who Want To Be The Best
Built Like a Tank
cool little fan. Was a little afraid of how well it would hold up after seeing it online, but a few months in and they're still cranking. Makes a much better experience for my construction crew.
The odor is gone. Great fan.
I originally bought it for a root cellar to keep air circulating. Put it on the portable outhouse and the odor is gone.
No Smell At All
Worked wonders for our outhouse. Since using these there's been a lot less smell or none at all."
Silent but CRANKING
It evacuates the tough smells of the porta potty. It's virtually silent, but that thing is cranking.
Simple, Reliable, and Beautifully Designed
It works almost all day long eliminating the heat. It's enough airflow for a large shed.
Completely Changes The Experience
Really easy to install. We've used these on our portable toilets at home building sites for over 5 months with no issues. It completely changes the experience inside. We won't go back. Highly recommend.
Makes a Noticeable Difference
I'd wait in line to use a portable toilet with this fan over a standard porta potty. Easy to use, efficient, and powerful enough to make a noticeable difference.

Questions
Quick answers about Spartan Sol's Jonny Hat features, setup, and support.
Spartan Sol creates simple, solar-powered upgrades for porta potties, sheds, outhouses, and other outdoor spaces. Our two flagship products are the Johnny Hat™ Solar Fan for ventilation and the Spartan Sol Motion Light™ for automatic lighting.
The Johnny Hat uses an integrated solar panel to power an exhaust fan that pulls hot, stale, and odorous air up through your existing vent pipe and exhausts it outside. When the sun is shining, the fan gets to work automatically.
The Johnny Hat is designed to fit standard 3" outside-diameter or 4" inside-diameter vent pipes, making it compatible with most standard portable restrooms.
Installation takes just seconds. Simply place the Johnny Hat onto your existing vent pipe—no wiring, tools, or complicated modifications required.
Yes. By continuously exhausting hot, stale air through the existing vent, the Johnny Hat helps reduce heat buildup and unpleasant odors inside the unit.
During the day, the integrated solar panel charges the light's built-in rechargeable battery. After dark, the motion sensor automatically activates the LEDs when someone enters the space.
It's designed for sheds, porta potties, outhouses, workshops, barns, job sites, utility buildings, and other spaces where running electrical wiring isn't practical.
