Make-Up Air Unit Manufacturers
No single MUA manufacturer is the right fit for every configuration. Sourcing across several make-up air unit manufacturers lets you match the unit to the application, not the application to one catalog.
We represent the make-up air manufacturers below, along with the louvers and dampers that complete the system.
You get the right unit specified from the right line for your airflow and tempering needs. The equipment carries strong manufacturer warranties, with one purchase order and one point of contact.
Find the Right Make-Up Air Configuration
Make-up air is specified by tempering method and heat or cool source. Pick the configuration you need below, then we match it to the right manufacturer line. To size the unit first, run our make-up air sizing calculator, or start at the make-up air unit hub to compare options.
- Tempered make-up air
- Untempered make-up air
- Direct gas-fired units
- Indirect gas-fired units
- DX-cooled units
- Dedicated outdoor air systems
- Rooftop units
Every line is backed by the manufacturer’s warranty, and we support that warranty so you are never left alone with the factory. Call 847-262-3457 ext. 23 and we will spec the right make-up air unit for your application.
Frequently Asked Questions
Why source make-up air units from a multi-line distributor instead of one manufacturer?
A single manufacturer pushes you toward what it builds. We carry several lines, so we spec the unit that fits your airflow and tempering needs, not the one that fills a catalog. You deal with one purchase order and one point of contact for the whole system.
Are these make-up air units made in the US?
Most of the lines we represent are built in the United States, and one is built in Canada. We can confirm the country of manufacture for any unit before you order. Every line is backed by the manufacturer’s warranty.
Do the make-up air units come with a manufacturer warranty?
Yes, each unit carries the manufacturer’s warranty, and we handle the warranty support directly. You are not left to chase the factory if something needs attention.
