I recently had to open a liquid line filter (Danfoss).
For a customer to carry out tests on.
As it was open i thought I would post a picture.
All that is missing is the 2 metal spiders from each end, which kept everything together.
Also note the end of the cintered filter shown on the r/hand side is solid.
Whereas from the l/hand end there is a hole bored in it.
The designed refrigerant flow is from Left to Right.
Through the cintered filter and the felt like material.
Which fits up against the metal strainer shown.
(The wax block is to keep the strainer in place, whilst i took the photo and not part of the filter)
