Make-Up Air (MUA) Models

Design: 100% replacement air with a fixed discharge air volume.

Function: Supplies direct replacement air for building mechanical exhaust.

Application: Used as make-up air for paint booths and other industrial processes which incorporate mechanical exhaust.

Fixed Recirculation (FR) Models

Design: Manual modulation of outdoor air from 0% to 100% with use of mixing box and potentiometer.

Function: Provides efficient, low-cost heating where minimum ventilation rates are required.

Application: Used in warehouses, distribution centers, retail outlets, etc.

Air Management (AM) Models

Design: Automatic modulation of outdoor air from 0% to 100% with use of mixing box and pressure gauge.

Function: Automatically responds to building pressure and temperature

needs.

Application: Used in industrial and commercial buildings that have air quality and specific air management requirements.
