AVT Inland 45 Vacuum Pump Fluid (Low vapour) - AVT Services Inland 45 Vacuum Pump Fluid. AVT Inland 45 is a synthetic hydrocarbon fluid that permits strain-free cold starts as a result of its low pour point and high viscosity index – their viscosity is lower than that of a typical vacuum pump oil at low temperatures. In addition, because Inland 45 maintains its viscosity at high temperatures, it provides a good seal under full-load conditions.
