Air Handling Units

Canada Blower Co. offers two major gas fired Air-Handling Unites (AHU) types: direct gas-fired and indirect gas-fired airhandlers.


Direct gas-fired AHUs have 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 ventilation area.


An indirect gas-fired AHU 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 recirculating air applications.


Though simple in principle of operation, direct gas-fired AHUs have sophisticated burner-control blower systems. Unit 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, supply fans, heating & cooling coils, outside air intake hoods, intake dampers, filters and burners.


AHU air-handler housings are made of galvanized or aluminized steel. Access panels are provided to access air 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) with forward-curved or backward-inclined blower 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 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 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 fan 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 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 units, a modulating bypass damper or profile plate maintains the airflow velocity within the specified velocity range. Otherwise, the burner can experience inefficient operation, generate odors in the occupied spaces served, and create an un-safe increase in certain products of combustion.

  Canada Blower FRP axial fans use an an aerodynamic drive housing to protect fan shafts, bearings and drive components from hazardous corrosives. FRP fans are designed for ventilation and industrial process applications where corrosive fumes may present in the air stream and / or surrounding atmosphere. All fan parts exposed to the airstreams are constructed of high-quality, corrosion-resistant fiberglass reinforced plastic. Harmful fumes are blocked from the shaft opening by a labyrynth grease seal.

High efficiency and low cost characterize Canada Blower ABD Fiberglass Tube Axial Fan designed for either horizontal or vertical exhaust systems. With 8 sizes from 18" to 60" diameter, volumes to 70,000 CFM and static pressures to 3" WC. A unique direct drive ADD-FRP bifurcator tubeaxial fan has its motor mounted inside a protective enclosure.

Two series of CBC FRP corrosion resistant roof exhausters fulfil most every installation and application requirement. In addition, specially formulated FRP resins can be applied to combat specific corrosives, such as organic chemicals. The innovative inline FRP centrifugal fans series combines the efficiency and reliability of the centrifugal fan with the low cost of tubeaxial fan. Precisely engineered conical inlet assures a smooth airflow to the impeller. Fan sizes from 6" to 36" inlet diameter offer capacities to 15,000 CFM and 2.5" WG static pressure.
