This is definitely the Lennox OEM part - Exactly the same

I noticed a previous negative review that mentioned it wasn't a Lennox part because it had Fasco on it. The original OEM part on my furnace also had Fasco references on it (Fasco makes this part for Lennox). This is my 2nd replacement in 25 years and it is definitely the Lennox OEM even though it has Fasco on a few labels. I received the part within 24 hours of ordering. Super fast service. The old unit was getting noisy bearings and I didn't want it crapping out during the coldest day of the year. Great price (half of other sites). The package came with the inducer, detailed Lennox instructions, the Gasket (I used my old as it was in good shape), 4 different orifices for various sized furnaces, 4 new screws. Super easy replacement.

Sent off brand instead of OEM brand ordered

I ordered a Lennox brand OEM furnace exhaust assembly and received a Fasco brand that I could have bought anywhere. I didn't have the time available to send it back so I installed it anyway. I had to move my gas line as the fasco assembly is slightly different. My receipt and order show Lennox brand and I payed premium dollar for it, I just didn't get it.

Great replacement part

Part seems to be high quality and the fit was plug and play. It has all the adapters you need for different size furnaces. Works perfectly, would buy again. Shipping was unusually fast to my door

Fit but slightly larger than OE

This installed and functions fine. However the OD was slightly larger than the original blower. My gas piping ran right underneath the blower housing. Therefore, I had to actually redo my gas piping in the furnace cabinet to accommodate. Was frustrating but can't complain. Glad a replacement was still available. This fit in a G26-75-2 which is not technically in the list on supply house as a cross referenced part.
