How automatic vent openers work:
Vent openers do not require
electricity. The opener has a metal cylinder containing a mineral which expands
when heated. This pushes a piston that opens the vent. As the temperature cools,
the mineral shrinks and a spring closes the vent and resets the piston. The opening
and closing of the vent is gradual allowing just the right amount of air flow
for cooling. Vent Opener Dimensions
