Thank you
One Blower will supply enough pressure and head. Barely.
If this is not enough then there will be more issues.
- Upsizing the motors to 25 will require the VFD's to be upsized and the disconnects as well as the backup generator.
- I cannot go to a smaller Blower because it will no...
Yes one blower will work but this is a critical application.
So if a Blower or drive fail the system will still operate until it is repaired.
Thank you for your input.
Very helpful and reassuring.
Thank you
I agree with everything you said.
I was given this project with this equipment to work.
Not knowing that much about air flow and pressure/velocity.
I normally deal with water.
This is my other solution to this that may work.
See attached.
Do you see any major issues other than the...
Sorry NOT 90 Amps. 90 Hertz.
System flow is a total of 1600 CFM and pressure required is 55 inWC.
See attached Blower curve.
There is only one common Transducer the reads the pressure off the side of the pipe not the velocity pressure.
When both are operating the one Blower will operate at an...
Thank you for your comments.

We have tried syncing the VFD's with no luck.
We are operating at 90 amps. 4800 rpms.
And we are using one common transducer.

Thank you for your request for clarification.
Operation #1: Blower #1 and Blower #2 are operating while Blower #3 is...
I am working on a project that feed air flow and pressure to Air Pumps to supply fresh water and air to fish in a Fish Farm.
I need to operate three Blowers (two operating at one time and alernate with the third)
My issue is when two blowers are operating at the same time one of the blowers will...
