Technical answers to common questions about air handling units.
Electronically Commutated (EC) motors are brushless DC motors that maintain peak electrical efficiency across their entire variable speed range. They consume up to 50% less power than traditional AC motors and operate with drastically lower acoustic noise, making them ideal for commercial FCUs.
A terminal HEPA filter is located at the very end of the ductwork, right at the ceiling diffuser of the cleanroom. This ensures the air is sterilized of 99.99% of particles down to 0.3 microns immediately before entering the occupied zone, preventing contamination from ductwork shedding.
A cleanroom AHU maintains positive pressure by supplying a slightly higher volumetric airflow (CFM) into the sterile core than what is mechanically extracted. High-static centrifugal blowers within the AHU force this excess air outward through airlocks, preventing contaminated ambient air from entering.
An enthalpy wheel is a rotating desiccant-coated matrix that transfers both sensible heat (temperature) and latent heat (humidity) between the hot incoming fresh air and the cold exhaust air, recovering up to 80% of the HVAC energy that would otherwise be wasted.
