Quick answer: This is the genuine ResMed side cover for the Air10 series — the AirSense 10 and AirCurve 10 devices (part 37303, charcoal). The side cover fits onto the side of the device in place of the humidifier, sealing the connection when you run the machine without the humidifier attached. It's what lets the Air10 be used humidifier-free — and a replacement if yours is lost or damaged. Device and humidifier not included.

Device and humidifier not included.
About this part
The Air10's humidifier attaches to the side of the device — and when you remove the humidifier, that connection needs to be closed off so the device can still run properly and hold pressure. The side cover is the piece that does that: it clips onto the side in place of the humidifier and seals the opening.
You need it whenever you want to run the Air10 without humidification — for example on a trip where you'd rather not carry or fill the water tub, or if you simply don't use humidification. It's also a straightforward replacement if the original was lost or damaged (it's a small part that's easy to misplace once the humidifier is left at home).
This is the charcoal version for the Air10 series (AirSense 10, AirCurve 10).
