The Federal Housing Administration and most state and local building codes recommend a minimum of one square foot (144 sq in) of ventilation per 300 square feet attic floor space. Bear in mind that this is a _MINIMUM_ recommendation. A number of factors s...
Depending on your local building code, you may need to either provide 1 square foot of ventilation per 150 sq. feet of attic space or 1 sq. ft. per 300 sq. feet. Once you determine the square footage of your attic, divide by either 150 or 300 to get...

Excess exhaust ventilation is preferable too insufficient intake ventilation. If a powered ventilator does not have enough intake ventilation, damage may occur to the motor. If a powered ventilator has too much exhaust ventilation, nothing damaging will o...
Sizing an industrial fan is typically done by determining the number of air changes per hour desired for the particular building's activities. At a minimum, you would want 4 air changes per hour. So for instance, you have a building 50 x 50 x 20, in ft...
A well-ventilated attic breathes-in (intake ventilation) and breathes-out (exhaust ventilation) through vents located at the lowest and highest parts of your attic. Properly placed, the correct "balance" of intake and exhaust vents will create a consta...
The difference between vents is the location. As hot air rises, the vents the air flows out of are exhaust. So by extension, the vents on the top of the roof are exhaust and the vents on the bottom where air flows in to the attic are intake.

The maximum environmental operating temperature for a Ventamatic Industrial Fan is 140 degrees farenheit.
Ventilation is a method of regulating the air in a particular area. For attics, generally the result expected is a reduction in temperature. A properly ventilated attic allows outside cooler air to enter an attic and push the hot air up and out. Another...
Attic temperatures should be within 15 degrees of outside air. A smaller temperature difference is preferable. Temperature differences in the attic cause more work for Air Conditioning systems and can also cause extra humidity in the attic.
It comes from normal household activities, such as showers, laundering and cooking activities that can release as much as three to five gallons of water vapor a day. If this water vapor becomes trapped in the attic, it can cause roof decking and shingles ...
