## Description

The Johhny Hat is a solar powered ventilation fan that has been designed to fit inside 4" PVC/ABS and over the top of 3'' PVC/ABS. Because of this, it can be used for almost any application! Without any additional parts the Johhny Hat can be mounted to nearly any portable restroom, added to existing vents on other structures, adapted to be used on dog houses, sheds, green houses, and a variety of holding tanks. With standard PVC or ABS parts you easily change the mounting angles or even add multiple fixtures together for larger areas. Unlike other solar powered fans, we have embraced the square/rectangle shape of solar panel cells. Because of this, we are able to capture 2-4 times the amount of solar power to have a more useable and reliable ventilation fan for whatever structure, room or holding tank you are trying to keep cool and odor free. *Solar powered products require direct sun exposure*

## Features

- Fits directly on 3'' pipe and in 4'' pipe (abs/pvc)
- Fan produces 40 CFM with a lifespan of 40,000+ hours
- Porta Potty Ventilation Fan.*Solar powered products require direct sunlight*.**Fan produces 40 CFM of air flow, larger spaces may require multiple units to properly ventilate the structure**
