Hi Charles,
The EBM-Papst model G2E085-AA01-01 will be sufficient for the 8877.
Of course, any blower will cause more noise then a fan.
If the tube is not run at full dissipation you can always reduce the blower
voltage and by that the noise level.
I use the G2E085 with 3x3CX800A7.

Subject: [Amps] Blower recommendations 8877 amp.
I'm looking for specific blower recommendations for a HB 8877 amp.
(blower maker and model #).
Everyone says use a Papst blower because they are quieter. I use a Papst
fan in my HB 2x3-500 amp.
I have several blowers here. The ones that obviously move enough air are WAY
too loud! The quiet ones I'm not sure about. They seem to move plenty of
air, but don't produce the amount of water level change recommended by
Eimac.
I built a liquid tube manometer gauge to measure the back pressure. Only
the loudest can deliver the minimum 0.41 inch change in water level that
Eimac recommends for the 8877. Surely, there are compromises that work just
fine.
What blower are you guys using in your single 8877 amps? Recommendations,
anyone?
