COMMERCIAL & INDUSTRIAL MAKE-UP AIR UNITS Serving Oshawa, Ajax, Pickering, Markham, Whitby, and Surrounding Areas

Make-Up Air Systems

Industrial facilities and large commercial buildings must be ventilated properly to ensure the safety and comfort of workers, guests and customers. 

To accomplish this, specialized air handling equipment should be put in place to help supply buildings with fresh air while removing the exhaust from industrial processes and HVAC systems.

The Best Way to Replenish Exhausted Indoor Air is by Using Make-Up Air (Mua) Units.

What is Make-Up Air?

Make-up air is designed to replace, or make up, indoor air that has been lost to exhaust fans, heating appliances and industrial processes.

As air gets used up inside a building, indoor air pressure drops, causing a variety of concerns such as poor indoor air quality, reduced HVAC efficiency and a noticeable increase in odours, dampness and general discomfort.

Why Your Building Needs Make-Up Air?

Make-up air solutions are essential for large buildings and industrial facilities. Not only does make-up air improve indoor air quality, but it also boosts your building's energy efficiency and reduces HVAC downtime.

Industrial facilities, commercial centers and large residential buildings benefit from make-up air in many ways, including:

  • Improved indoor air quality
  • Increased worker productivity and occupant comfort
  • Consistent temperature and humidity levels
  • Reduced overall HVAC costs
  • Improved performance of building exhaust systems
  • Reduced haze, odours and indoor air polluting particulates.
