Practically all air removed from a building is replaced by outside air at the same rate. Outside air will enter by any means available, when the inside air pressure is less than outside air pressure. This happens when exhaust exceeds supply systems capacity to replenish the building envelope with air. Possible consequences of this negative pressure differential are degraded exhaust system performance, loss of environmental control, adverse safety and performance effects on appliances which combust fuel and processes which vent gaseous products via natural draft, increased building structural loads, and excessive forces on exterior doors. Unfortunately, these problems occur where an inadequate amount of replacement or make-up air has been provided. A good make-up air system will alleviate all of these ills by providing the correct amount of replacement air. It may also reduce plant overhead by lowering heating, cooling, and ventilating costs.

In many areas, air must be conditioned before entering a facility. This necessitates that the make-up air system have heating and often air cooling and filtering abilities. A so called make-up air unit is required. Typically a make-up air system includes an air mover section, usually a propeller or centrifugal type fan, an air tempering section containing heating and where necessary cooling and filtering equipment, and a control system.

Fan selection and power requirements are generally determined by the application. When only general ventilation is required (fan pressure requirements are low), a propeller type fan can be utilized. To supply make up air through a duct system with a resistance of 0.5 in w.g. or more, a centrifugal fan should be considered. In either system, diffusers may be used to direct the discharge air velocity.

Special Duty Products
 
Canada Blower Fan can provide industrial air moving equipment to meet your specific requirements. Our marine duty equipment provides reliable, proven performance to meet the specialized needs of the marine market, including all welded marine construction on most models.

Marine Duty Fans and Blowers

Canada Blower Marine Duty installations require more than a standard industrial fan or blower, they require Hartzell Marine Duty Fans and Blowers. The reliability, low maintenance, long life, corrosion resistance, heavy duty construction, and the flow and pressure capability in a compact package all required come together in our marine duty fans. Canada Blower Marine Duty Fans and Blowers are constructed to meet or exceed U.S. Coast Guard and U.S. Maritime Administration Standards.

Mine Duty Blowers and Heaters

All Canada Blower Mine Duty Blowers and Heaters are designed to meet the severe application conditions found in typical mine environments. They are designed for reliability, low maintenance, long life, corrosion resistance, and heavy duty construction.

Adjustable Pitch Fans and Fan Assemblies

Canada Blower has several types of fan assemblies available in a variety of performance capabilities.

OEM Products & Parts

Canada Blower meets the needs of OEMs with both standard and customized products designed specifically for the OEM’s equipment, package, or system requirements. Canada Blower’s product lines and customization capabilities provide solutions for a broad range of environmental air moving problems.

Make-up Air and Heating Equipment

Canada Blower Fan heating equipment is available with custom capabilities for both heating and cooling needs for a broad performance range. It provides the most efficient method for heating supply air from outdoors and helps other fan systems and process equipment operate more effectively. In addition, re-circulation options available.

Direct Gas Fired Heating Equipment

Canada Blower Direct gas-fired make up air units are the heating equipment choice when gas is the source available. These heating units are available with propeller, backward curved, and forward curved centrifugal wheels and are designed to eliminate hot and cold spots in the plant, supplying fresh, clean air at the right temperature. Existing ventilation systems will work better, which accommodates more effective employees and production systems.

Steam Air Intake Units AHU

Canada Blower steam make up air units are the heating equipment choice when steam is the source available. These Canada Blower airhandler units are available with propeller and forward curved centrifugal wheels and are designed to eliminate hot and cold spots in the plant, supplying fresh, clean air at the right temperature. Existing ventilation systems will work better, which accommodates more effective employees and production systems.

In situations where the inside air quality is acceptable, often a portion of the inside air may be drawn back through the make-up air unit where it is recirculated back into the building. Advantages of using Hartzell Recirculating Make-Up Air units are lowered heating costs, better indoor air mixing (reduced air stratification), as well as constant building pressurization.
