Buffalo Blower
Co. produces industrial Make-Up Air Unitss for ventilation and heating
of large industrial facilities. Makeup air is vitally important to the
health and welfare of a building and its occupants. If the proper
amount of makeup air is not introduced into a space, consequences can
range from exterior doors that are hard to open or close, to buildups
of carbon monoxide in the space, to fume hoods that don't actually
control the contaminants they were intended to control. In addition,
the outside air that is brought into a building to "make up" the amount
of air that has been exhausted has a very significant impact on cooling
and heating capacities. A simple roof ventilator is essentially an
opening in the roof with a cover to keep out rain and to prevent winds
from interfering with its functioning. Natural convection is an
appreciable aid to ventilation in a large building only if it contains
sources of large amounts of heat. A further useful adjunct is a fan
fan, device for agitating air or gases or moving them from one location
to another. Mechanical fans with revolving blades are used for
ventilation, in manufacturing, in winnowing grain, to remove dust,
cuttings, or other waste, or to provide draft for a fire. The addition
of distribution ducts to the fan and a system for forcing air into the
building provides greater efficiency. Outlets are designed to attain
maximum mixing of air and to move large amounts of air at low velocity
so that temperature layers are eliminated. Factories have special
suction hoods and enclosures to draw away localized dust, fumes, and
heat. Incoming air may be cleaned of dust by filters or electrostatic
precipitators.
