Premium Compressor Oil




Applications: This concentrated cleaner and system flush is a solvent-type fluid designed to dissolve varnish and solubilize sludge as an additive at 5% to 10% concentration in oil for cleaning many types of industrial systems such as Bowser Sumps in Paper Mills during operation. (Not for use in Ammonia Compressors or with Polyalkylene gylcol or silicone fluids.)

It can also be used to help flush a system when changing-over from mineral to synthetic oils in order to reduce contamination due to oil carry-over. Regular use of Ultra-Solv will help you get the most of out your synthetic oil and your equipment by removing varnish and reducing operating temperature.

Typical Industrial Applications: Rotary Screw Compressors, Rotary Vane Compressors, Centrifugal Compressors, Reciprocating Compressors, Hydraulic Sytems, Gearboxes, Vacuum Pumps, Chains, Bearings, Reservoirs, Airline Valves, and Heat Transfer Systems

Performance Benefits:

  • Economical to use - only 5% concentration required for most applications
  • Solubilizes and removes harmful varnish and "sludge"
  • Compatible with mineral oils and synthetic hydrocarbons
  • Safe to use as directed - does not contain carcinogens or other hazardous materials found in some competitors products
  • Very mild odor
  • High flash point

Cleaning Procedure: We recommend the use of 5% to 10%, generally 5%, of the cleaner with 90% to 95% of the fluid in the system. This oil can be used with petroleum and synthetic hydrocarbon (PAO) oils. Temperature/time concentration relationships for industrial equipment: (oil should be circulating.)

Run equipment at normal operating conditions. Do not exceed 300°F. Change the oil filter before and after cleaning. Inspect during cleaning if equipment is very dirty. Some filters are equipped with pressure drop gauges. Normally, a 10psi drop indicates that the filter should be changed.

For safety reasons allow oil to cool (130°F) before draining. After draining, it is recommended that the oil system be flushed with clean oil. To flush, fill to minimum or normal oil level. Start equipment to circulate or splash oil around system. In gearboxes or other applications where heavy oil is normall used, stop equipment almost immediately after starting to prevent wear.

Product Compatibility: This oil is safe for use on ferrous and nonferrous metals used in industrial equipment. It is safe on most seals used in industrial equipment at 10% maximum concentrations.
