Megavent

CV01 commercial roof vent opener, made for large greenhouses and pavilions.

Vent openers open and close on their own at set temperatures, so they're a great way to manage greenhouse temperature without any electricity. Using a temperature-sensitive wax mechanism, each of our vent openers starts to open once it reaches somewhere between 17 and 24 degrees Celsius (you can adjust the range). They stay open until the temperature drops back below that 17 to 24 degree range. Whatever load the vent has to lift, our range has you covered, from the smallest residential roof vent opener to side louvre openers and large commercial roof vent openers that stand up to strong winds.

These vent openers are an easy way to manage temperature and airflow in your greenhouse without electricity.
