Freshman Air Handling Units

The Freshman series classroom units are flexible non-packaged units (no compressor) that allow for greater design options and cabinet choices, and that’s just the beginning.

Using a hat trick of sound guidelines and standards to give teachers and students the absolute quietest units in North America.

Our Intelligently Quiet (IQ) design is backed by:

AMCA Standard 300-08 – Our sound laboratory is an AMCA-accredited reverberant room. Reverberant room method for sound testing in accordance with AMCA Standard.
ANSI/ASA S12.60 – Sound guidelines and requirements for schools – designing a classroom with reliable data
AHRI 260 – tested in accordance with AHRI 260 – sound rating of ducted air moving in conditioned equipment

Our Freshman IQ units are the only classroom unit that bears the AMCA label for sound, and adhere to the above three standards and guidelines which means you get the quietest unit ventilator for your classroom needs.
