Make-Up Air Units AHU (mua, makeup air unit):

Canada Blower Airhanles AHU is  complete ventilation system consists of equal parts exhaust air and replacement air. Exhausting air is a simple concept that is understood; however, the corresponding replacement air, commonly referred to as make-up air, is often misunderstood or overlooked.

The ill effects of an unbalanced ventilation system are widespread and have a significant impact on everything from personal health to manufacturing processes.

For this reason, Canada Blower iocuses on replacement air and the corresponding make-up air unit to provide it (aka MUA unit).

Canada Blower makes two primary gas-fired AHU types: direct gas-fired and indirect gas-fired airhandlers.


A direct gas-fired AHU airhandler has a gas burner installed directly in the outside makeup-air stream. The products of combustion (carbon dioxide [CO2], carbon monoxide [CO], nitrogen dioxide [NO2]) are discharged directly into the makeup air stream and supplied to the building area.


An indirect gas-fired AHU airhandler has a sealed combustion air chamber where all products of combustion are discharged through a flue to the outside environment and no products of combustion are discharged within the make-up air supplied to the building. Such equipment also frequently is utilized for recirculation air applications.


Though simple in principle of operation, direct gas-fired air-handling units AHUs have sophisticated burner-control systems. Unit fan sizes range from 1,000 cfm with a heating capacity of 80,000 Btuh to 100,000 cfm with a heating capacity of 15 million Btuh. Direct-gas-fired-AHU components usually include housings, air supply fans and blowers, outside air intake air hoods, intake air dampers, ventilation filters and blower burners.


AHU fan housings are made of galvanized or aluminized steel. Access panels are provided to access dampers, filters, burners, and fans / motors. AHUs located outside are provided with a sloped roof and standing seam joints.


Fans typically are double-width double-inlet (DWDI) ventilators with forward-curved or backward-inclined fan wheel blades. Fans can come with open drip-proof (ODP) or totally enclosed fan cooled (TEFC) motors. The most typical external static pressure in the 2- to 3-in.-wg range. Because most outside istalled air handling units can operate below 0°F, fan motors and bearings are rated to handle lower temperatures. For applications that require supply-air temperatures higher than 110°F, the motors and fan bearings are rated for maximum design operating temperatures when placed in draw-through configurations.


Outside air intake hoods or weather hoods are designed for an installation specific location and usually provided with bird screens. Outside-air intake isolation air dampers are furnished to prevent cold air from dropping through a unit into a warm building and warm air from escaping through a unit during winter months, when it is not in operation. Low-leakage parallel blade isolation air-handler dampers are most standard. The fan discharge is located at the opposite to isolation-damper position.


A filter cabinet normally has 30/30 filters in a V-bank configuration to increase filter area and reduce static-pressure drop across the filters. Higher-efficiency filters are used on application.


A burner consists of a cast-iron or aluminum pipe assembly with drilled gas orifices. The fuel-air mixing is controlled by perforated stainless-steel baffles attached to the pipe assembly. The burner blower can be placed in the outside airstream or in the outside / return mixed-air stream. But to prevent potentially hazardous combustion byproducts of indoor-air contaminants, the burner is placed in the outside airstream only. The required airflow across the burner must be within a specific velocity range (typically 2,500 to 3,500 fpm) for proper combustion. For variable airflow air handling units, a modulating bypass damper or profile plate maintains the airflow velocity of the airhandler within the specified velocity range. Otherwise, the burner blower can experience inefficient operation, generate odors in the occupied spaces served, and create an un-safe increase in certain products of combustion.

Economical small pressure blowers - Canada Blower APB series fans:  
Canada Blower Co. offers different types of Industrial Make-Up Air Systems for larger industrial plants ventilation needs. An improvement in the at industrial facilities environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees.

Air-Handling Units for Make-Up Air and Space Pressurization Applications have the following features:

- Outlet Temperature is usually monitored with a probe mounted near the outlet of the unit.

- Discharge Air Temperature is set at the control panel or using a remote control station.

- Gas input is “modulated” using a butterfly valve, actuator, and controller.

For Space Heating Applications, a room thermostat is used to control outlet temperature. On a call for heat, the unit will provide air heated to the maximum allowed temperature until the room thermostat is satisfied. Once satisfied, the unit will either turn off or will continue to operate at a reduced outlet temperature.

An override option may also be supplied. In this case a room thermostat is supplied in addition to the basic system. The unit is set to full-fire when room temperature falls too low.

Direct Spark units are supplied with an ignition transformer for the igniter.

Piloted Units are supplied with a solenoid-operated Automatic Pilot Valve and a small pressure regulator – around 20,000 BTU – as well as an ignition transformer for the pilot spark igniter.

Pre-purge of the system (by starting the blower for a specified time to provide a minimum air volume change) before ignition of main burner is not required by ANSI code, but is frequently specified by the user. This should be provided whenever a building contains flammable dusts or vapors that could potentially reach and collect within a direct gas-fired unit while it is idle.

To assure safe operation of a direct gas-fired heating system, a number of Safety Interlocks are commonly provided:

A. Damper Limit Switch – Dampers must be fully open before unit will operate.

B. Air Proving Switch – Located near outlet of unit to prove air flow before igniting burner.

C. Flame Supervision – Discussed above. Shuts down unit on flame failure.

D. High Temperature Limit – Signals unit to reduce gas supply when maximum allowable temperature is reached. If air temperature exceeds limit, the unit is shut down.

E. High Gas Pressure Switch – Shuts down unit to protect regulator against spikes in inlet gas pressure.

F. Low Gas Pressure Switch – Shuts down unit when low inlet pressure detected. Redundant safety device, since low flame would also shut down unit.

G. Safety Shut-off Valve – Responds to various inputs listed above – closes off gas supply.

Direct Gas-Fired Air Heating Systems are a class of equipment utilized primarily in industrial and
commercial environments to provide for worker comfort. To a lesser extent, these systems are
used to condition air for process and finishing applications such as material drying and paint
