Dymavac Industrial: is a severely hydrotreated base oil that is not put through the same degree of molecular distillation that our other rotary vane pump oils are. Hence, it is the lowest cost hydrotreated vacuum oil, and was created to provide bulk purchasers with a higher quality, vacuum-specific, competitively priced alternative to their use of hydraulic and turbine oils in vacuum systems. Dymavac Industrial is non-polar with virtually no aromatic molecular content, and exhibits very low sludge and varnish forming tendencies compared to solvent refined oils. The user will experience lower vapour pressure and reduced backstreaming in their system compared to one running on hydraulic/turbine oils. Dymavac Industrial is custom-blended for the customer to meet their specific viscosity requirements. Dymavac Vacuum
Flushing Oil: is a severely hydrotreated base oil designed for a between oil change
procedure to assist in removing particulate and contaminants remaining in all types of
vane and piston pumps. This clear, colourless, odorless oil has a light viscosity nature
of 3.6 cSt at 40 ° C, and an ultimate pressure of 1 x 10- |
