At back of that compressor is liquid/vapor injection fitting and what you describing as filter, it should be filter.
Do you have photo of that to confirm?

It's called a Discharge Temperature Control Valve (DTC). It's a liquid injection valve used to cool the compressor in low temperature applications.

Here's the link to Copeland AE bulletins.
