Coalescing Oil Return Line Setup

Over time, oil will accumulate on the coalescing side 
of the oil separator. As a result, an oil return line with a 
shut-off valve, sight-glass, check valve and needle valve 
are installed between the coalescing side and compres-
sor to return this oil back to the compressor.

To  adjust  the  return  flow,  proceed  with  the  follow 

procedure:

NOTE

Do not fully open the needle valve unless directed by 

Vilter

TM

  Technical Support. Leaving the needle valve 

fully open will reduce efficiency of the compressor unit.

1.  Open shut-off valve on coalescing side of oil separa-

tor, see Figure 4-13.

2.  While the unit is in operation, crack open needle 

valve and observe oil flow through sight-glass.

3.  Slowly open needle valve more until a small amount 

of oil is seen in the sight-glass.

NOTE

The sight-glass should never be full with oil.

4.  Periodically check oil in the sight-glass and ensure 

that there is flow.
