Changing the Compressor Coalescing Filter

Read the
“Maintenance and Repair” safety section
before working on the system.

Ensure the new filter is a VMAC filter, part #
3600088. This is a high-pressure filter. Use of other
filters not rated to the required pressure may cause
the filter to rupture.
The oil does not need to be drained to change the
coalescing filter.
1) Clean the tank in the area of the coalescing filter to prevent
contamination.
2) Remove the spin-on type coalescing filter by turning it
counterclockwise.
3) Check the gasket-sealing surface of the manifold block for
contamination, old gasket material or damage.
4) Apply a thin coating of compressor oil to the filter-sealing gasket.
5) Spin the filter clockwise onto the threaded nipple until the gasket
contacts the sealing surface on the tank, then tighten the filter an
additional 3/4 to 1 turn to seat the sealing gasket.
6) Operate the system and check for leaks.
