Question: Will this fan work in an APC AR3100 rack
Answer: Thank you for your inquiry. This particular fan unit is for 750mm wide APC racks.
For the 600mm wide AR3100, you will want to use the 120V ACF501 (http://www.server-rack-online.com/acf501.html
) or the 208V ACF502 (http://www.server-rack-online.com/acf502.html
Question: Could this product fit a AR3810 Netshelter rack? If not what would be the appropriate roof top fan kit?
Answer: Thank you for your inquiry,
The ACF503 roof fan would not be compatible with your APC AR3810 due to the dimensions. However, the APC ACF505 roof fan kit would be. We do not currently have the ACF505 online, but we can absolutely supply that unit - we have it currently on sale for $261.18 ($329.99 list).
Alternatively, you could get the APC ACF400
rear door cooling unit which would also be compatible with your rack.
