Section VII - Compressor Fluids
QuinSyn Flush
QuinSyn Flush is a specially formulated
synthetic fluid capable of dissolving varnish
and solubilizing sludge from lubricating
systems while they are operating.
QuinSyn Flush contains oxidation and rust
inhibitors, and can be used as a short-
term fluid (for a maximum of 500 hours).
It is fully compatible with mineral oils and
QuinSyn synthetic fluids, and is highly
recommended for use as a flushing fluid
when converting to QuinSyn PG from
QuinSyn or QuinSyn IV.
Applications
Cleaning fluid for removal of varnish, dirt
and oxidized fluid from compressor fluid
systems.
Flushing fluid when changing from other
fluids to QuinSyn fluids.
