Hello Friends,
I am in bit of a confusion here. I have 2 kinds of fans used for industrial unit cooling. The current fan is nearing its obsolescence and I am looking for a new fan with same or better specifications to replace the older fans.
Following are some specs.
Old Fan:
Rated Speed: 4300 RPM
Air Delivery: 19 CFM
Static Pressure: 0.18 inch - H2O
Rated Current: 290 mA
New Fan:
Rated Speed: 3900 RPM
Air Delivery: 19.07 CFM
Static Pressure: 0.095 inch - H2O
Rated Current: 260 mA
Below is my opinion about the new fan, please correct me if I am wrong.
Rated speed: Slower than Original fan but doesn't matter as long as CFM ratings are better.
Air Delivery: New fan has better CFM
Static Pressure: : I am not able to figure if the rating for the new fans is worse, same or better than Older fan given other parameters.
Rated current: Better.
ALso, The form, fit and function of both the fans is identical.
Any and all the help would be highly appreciated.
Thanks,
Jambhu
