Our lungs appreciate the clean, unpolluted air that these natural settings offer. Now, have you ever taken that same type of deep breath when you enter your home or workplace? It is
What is an Electronically Commutated EC Motor?
What is an Electronically Commutated EC Motor? An electronically commutated (EC) motor is designed to run on an alternating current (AC) power supply, but it in fact bears a closer resemblance to a direct current (DC) motor. It is essentially a permanent magnet, brushless DC motor that incorporates on-board electronics. The added electronics allow an
IRIS Dampers – Technical Article
Dampers are commonly used in HVAC applications to regulate airflow within a duct or other air-handling equipment. Applications, efficiencies, power consumption, maintenance costs, and their effect on airflow vary widely. Conventional dampers typically comprise a valve, blade or plate in a frame.
