Function descriptions:

1. Improving air circulation
Taking advantage of the free & clean solar energy, this roof exhaust fan will pump out the interior heat &
moisture to balance your house temperature, so as to provide a refreshing ventilation and more
environmental-friendly surrounding, and to lower down
your general power consumption cost.

2. Extending roofing lifespan
Being exposed long to the strong sun, your roofing underlayment may go weak and even lose efficiency
under the very high temperature. This roof ventilator can help reduce such heat to prolong their lifespan and
to help you save certain maintenance or replacement fee.

3. Reducing moisture & harmful mildews
When collided with chilly attic-roof in winter, the interior warm & humid air will condense into water droplets, such
saturated humidity might cause dangerous electrical short circuit or create mildews to harm your plasterboards. An
adequate & more active indoor ventilation provided by this exhaust fan can help remove these moisture contents &
harmful elements for you.

4. Preventing ice-dam
In snowy winter, interior warm air could melt those snows at roof to generate droplets falling down to the
eaves. These droplets will then refreeze into ice damming on your roof and arousing dangers, this solar
ventilator can help preventing such unsafe factors through keeping the indoor environment dry.
