Frequently Asked Questions

What is the main difference between an Air Handling Unit (AHU) and a Fan Coil Unit (FCU)?

An AHU is a larger, centralized system that conditions and circulates air for a large area or an entire building as part of a main HVAC system. An FCU is a smaller, simpler unit designed to condition the air within a single room or zone, typically using just a coil and a fan.

How can I improve the indoor air quality (IAQ) of my building using my AHU?

You can significantly improve IAQ by upgrading to higher MERV-rated filters to capture smaller particles, installing UV-C germicidal lights to neutralize pathogens, and ensuring proper humidity control. Regular coil and drain pan cleaning is also essential.

What is an EC motor, and why is it better for AHU fans?

An Electronically Commutated (EC) motor is a highly efficient brushless DC motor. Retrofitting an AHU's fan with an EC motor or fan array can reduce fan energy consumption by 30-50%, offers better speed control, and operates more quietly than traditional AC motors.
