QuinSyn Flush

QuinSyn Flush Cleaning and Flushing With 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 shortterm 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.

A. Mineral Oils -

Drain compressor thoroughly while hot including all the low areas. Shut down and lockout the machine.

Detach lines and drain. Inspect machine; if clean, change filters and separator elements and proceed as follows:

Fill with QuinSyn Flush and run machine until it reaches normal operating temperature. Drain and refill with a fresh charge of the

QuinSyn fluid selected for your machine. Send a fluid sample to

Quincy Compressor® Fluid Analysis at 200 hours.

B. Polyalklene glycols (PAG) or Silicone -

Drain compressor thoroughly as in (A). Fill machine with QuinSyn Flush and run for 500 hours. Send a fluid sample to Quincy Compressor®

Fluid Analysis. Flush may need to be repeated several times. Analysis will determine if further flushes are needed.

Fill with the QuinSyn fluid selected for your machine. Send a fluid sample to Quincy Compressor® Fluid

Analysis at 200 hours.

Varnished Machines Always clean slightly varnished machines using mineral oils or PAO fluids with QuinSyn Flush using the following procedure: Drain thoroughly as in (A) and fill with QuinSyn Flush. Run the machine for 300 hours and take a fluid sample. Send fluid sample to Quincy Compressor® Fluid Analysis to determine if further flushes are needed. Continue compressor operation until results of fluid analysis are reported. Drain or continue operation as advised by fluid analysis.

Always clean medium to heavily varnished machines using mineral oils or PAO fluids with QuinSyn Flush using the following procedure: Drain thoroughly as in (A) and fill with QuinSyn Flush. Run the machine for 300 hours and take a fluid sample. Send fluid sample to Quincy Compressor® Fluid Analysis to determine if further flushes are needed. Run the flush for an additional 300 hours. Drain thoroughly as in (A) and inspect the compressor. If clean, flush with another half charge of QuinSyn Flush and run for 30 minutes. Drain completely. Change filters and separator elements and fill with a fresh charge of the QuinSyn fluid selected for your machine. Send fluid sample to Quincy Compressor® Fluid Analysis at 200 hours.

extremely varnished machines should not be put back into service until mechanically or chemically cleaned. After proper cleaning, fill with a fresh charge of the QuinSyn fluid selected for your machine. Send fluid sample to Quincy Compressor® Fluid Analysis at 200 hours.
