Is this a legal compressor?

[Team996]

Our team was wondering if this is a legal compressor?

Nope looks illegal to me according to <R90>

<R90> Items specifically PROHIBITED from use on the ROBOT include:
 Any air compressor other than, or in addition to, the one provided in the Kit Of Parts.
 Pneumatic cylinders and actuators different from those in the Kit or found on the Free
Pneumatic Components Order form, with the exception of those specifically permitted by Rule <R89>.

Emphasis mine
