What is a make-up air unit and how does it work?

A make-up air unit is a ventilation system designed to supply fresh, tempered air to a building to replace air that has been exhausted. It works by drawing in outside air, heating or cooling it to the desired temperature, and then distributing it throughout the space to maintain indoor air quality and pressure balance.

How do I size a make-up air unit?

Sizing a make-up air unit involves calculating the air volume required to replace the exhausted air, considering factors such as the building's size, occupancy, and specific ventilation needs. Our account managers can assist you in this process using our advanced selection software to ensure optimal performance and efficiency.

What are the benefits of make-up air unit?

Make-up air units improve indoor air quality, maintain proper air pressure balance, and enhance occupant comfort by providing a consistent supply of fresh air. They also help to reduce energy costs by tempering incoming air to the desired temperature.

What is the difference between a make-up air unit and a DOAS?

The primary difference is their function: a make-up air unit focuses on replacing exhausted air to maintain air pressure balance, while a Dedicated Outdoor Air System (DOAS) is designed to provide 100% outdoor air for ventilation purposes, often with advanced humidity and temperature control features.

Can a make-up air unit do more than just heating?

Yes, make-up air units can provide both heating and cooling, as well as humidity control, to ensure optimal indoor air quality and comfort throughout the year.
