Hello. To help with your two questions: 1) The CFM will depend on the site. When we install a fan we ensure that the benchmark airflow is matched or improved such that the air handling unit is working as it was or better. 2) Our EC fans have built in speed control options that can be accessed by a BMS. No other external VFD should be used. Thank you for your inquiry. Simon
@@BeWater22 Hi, in order to change the speed 2 methods are suggested. 1. ModBus - this gives full two way control to a defined speed. 2. 0-10V or 0-20mA input. These driving signals will drive the fan speed up and down but not to a defined speed. Do not change the supply voltage. I trust this helps. Simon
need to understand on the CFM level (air flow) post installation of EC fans, can we get same CFM like earlier? alos let us know EC fans are driven through VFD

Hi, I'm interested to do replacement to my home unit. just need to know what is the noise level for the replacement fan in dbm?
Uhh... that belt-driven fan was a "gerbil-cage fan," right? Then it already _is_ centrifugal.
