IFR air raise calcs

[jimbobNTL]

I did the calculations on a IFR we are planning to air raise in a couple months. Its 110' diameter with a combined weight of 250.59t. I came up with 302 mm h20. can someone verify my numbers are correct?

Also, I'm trying to source fans for the project. i cant seems to find ones that meet the requirements. Would anyone be willing to share a link to where i may find what I'm looking for?

I've been part of many air raising projects, but this is my first time on calculation and set up side of it.

thank you

Define what is "t"

Short ton, long ton or metric tonne.

Seems to be about right but define this first.

I suspect you need a "blower" not a "fan", so search for that instead.

Air raising or "hair" raising....?

It appears this is a huge fan with 302 mm H2O fan head.

TLT fans is a company supplying FD/ID fans for coal power plants which look similar in size and rating.

Howden is another company.
