Kitchen Exhaust System
Variar commercial kitchen exhaust system manufacturers in Chennai offer you the World Class
Commercial Kitchen Exhausts systems that keep your Kitchen environment conducive to human comfort
despite any changes in internal heat loads from burners, ovens, and Electrical fryers.kitchen exhaust
system is a device containing a centrifugual blower fan that mounted above the ranges of commercial
kitchen equipment manufacturers in chennai in the cooking area . It removes airborne grease,
combustion products, fumes, smoke, odors, heat, and steam from the air by exhaust of the air . In
commercial kitchens exhaust system are often used in combination with fire suppression equipments so
that fumes from a fumes are properly exhausted and the fire is put off quickly. Commercial exhaust
system may also be combined with a fresh air blowers that sucks the exterior air, circulating it with the
cooking fumes, which is then drawn out by the hood.In most commercial kitchen exhaust system, a
filtration system removes grease thru the baffel type grease trap filters and other particles. Although
many exhaust system to exhaust air to the outside, some recirculate the air to the kitchen.
Centrifugal blowers use the kinetic energy of the impellers to increase the volume of the air stream,
which in turn moves them against the resistance caused by ducts, dampers and other components.
Centrifugal fans displace air radially, changing the direction (typically by 90°) of the airflow. They are
sturdy, quiet, reliable, and capable of operating over a wide range of conditions , centrifugal fans are
constant displacement devices or constant volume devices, meaning that, at a constant fan speed, a
centrifugal fan moves a relatively constant volume of air rather than a constant mass. This means that
the air velocity in a system is fixed even though the mass flow rate through the fan is not
Centrifugal fans are not positive displacement devices. Centrifugal fans have certain advantages and
disadvantages when contrasted with positive-displacement blowers.
The centrifugal fan and blowers is one of the most widely used hvls fan chennai. Centrifugal fans are by
far the most prevalent type of fan used in the HVAC industry today. They are often cheaper than axial
fans and simpler in construction.They are used in transporting gas or materials and in ventilation
systems for buildingsand vehicles. They are also well-suited for industrial air cooler processes and air
pollution control systems.
The centrifugal fan is a drum shape composed of a number of fan blades mounted around a hub. As
shown in the animated figure, the hub turns on a driveshaft mounted in bearings in the fan housing. The
gas enters from the side of the fan wheels, turns 90 degrees and accelerates due to centrifugal force as
it flows over the fan blades and exits the fan.
