Direct Gas-Fired Make-up Air Units supply tempered and filtered air to the indoor environment. In summer, a direct-fired unit may be used as an air handler, with the heater disabled. By adding a DX or evaporative cooling section to the unit, it may be used to supply conditioned air year round.
While there are no facts and figures to show how many buildings in the United States provide the correct amount of makeup air, it can be surmised that there are probably a great many that do not have sufficient makeup air. And there's no one solution that is available for every building. Each building must be analyzed with a careful air balance calculation and evaluated based on the diversity of sources of exhaust air and infiltration.
Make-Up Air Volume Requirements:
The recommended method for calculating Make-up Air Volume is to determine the total CFM capacity of exhaust fans, blowers, stacks, etc. in the building and add 10%. This will create a positive pressure in the building ventilating.com fanblower.com highpressureblower.net industrialblowerfan.com industrialfanblower.net industrialfanblower.com pressureblower.net northernindustrialsupplycompany.com industrialpressureblower.com tenderall.com chicagoblowercanada.com cbblower.com buffaloblower.com buffalofan.com nis-co.com canadianblower.com olegsystems.com canadablower.com abbblower.com acmefan.net industrialblower.net fansandblowers.net americanblower.net barryfan.com cincinnatifan.net canadafans.com barryfan.net pennbarry.net pennfan.net tcffan.co.
Canada Blower ACX centrifugal roof ventilator is designed for roof mounted exhaust of relatively clean air in a wide variety of industrial and commercial ventilation applications. The ACX fan features a high efficiency, non-overloading backward inclined centrifugal fan wheel precisely matched to a deep spun venturi. The fan wheel, motor and fan drive assembly are completely isolated from the fan supports by rubber isolators to reduce transmission of noise and vibration. The top cap also provides complete protection for the fan motor and drive assembly, while allowing quick access to these components without the need for tools.
Canada Blower ATB ventilator is designed for roof mounted exhaust of relatively clean air for applications that require the exhausted air to be moved up and away from the building and where re-entry into the building supply air is possible. The ATB fan features a high efficiency, non-overloading backward inclined centrifugal ventialtor wheel precisely matched to a deep spun venturi. The blower wheel, motor and drive assembly are completely isolated from the fan supports by rubber isolators to reduce transmission of noise and vibration. The top cap also provides complete protection for the fan motor and drive assembly, while allowing quick access to these components without the need for tools.
Canada Blower AWX centrifugal wall ventilator is designed for horizontal wall-mounted configurations exhausting clean air in a wide variety of industrial and commercial ventilation applications. Canada Blower AWX ventilator features a high efficiency, non-overloading backward inclined centrifugal fan wheel precisely matched to a deep spun venturi. The fan wheel, motor and drive assembly are completely isolated from the fan supports by rubber isolators to reduce transmission of noise and vibration. The fan's top cap also provides complete protection for the motor and drive assembly, while allowing quick access to these components without the need for tools.

Industrial Direct-Fired Airhandling Units
In industrial environments where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees.

Proper Building Ventilating
A proper ventilation system for a roof is often the single most important factor which governs its longevity. A roof having a good ventilation system, along with proper maintenance will live approximately 25% more than any other roof.
