8.1 AIR TOOL OIL SPECIFICATION
Air tool oil viscosity refers to it’s properties to flow and how it reacts with heat. A low viscosity is
thinner than a high viscosity.
Air tool oil becomes thinner as it heats so choosing the right viscosity is essential. If the viscosity is
too low it may provide insufficient lubrication when heated. Equally, if it is too high, the fluid may
provide excessive resistance to move through the lines when cold.
The ISO (International Standards Organisation) viscosity grading system measures the kinematic
viscosity in centistokes (cSt) at 40º which is todays accepted standard. The SAE (Society of
Automotive Engineers) viscosity grade value is based on a scale.
This equipment is suited to an ISO grade 22 – 32 (SAE grade 5W – 15W) monograde oil.
The oil must be constantly supplied to the equipment during use to ensure complete lubrication and
optimum performance is achieved. It also acts as a rust inhibitor when the equipment is not in use.
We recommend the use of Draper Air Tool Oil:
This air tool operates at a maximum pressure of 90psi and must be controlled via a combination
pressure regulator, in-line lubricator and moisture filter such as the Draper range (see you local Draper
stockist) which with proper maintenance will ensure a constant supply of dry air and lubricating oil at all
times (see illustration below). Always check machine operating pressure before use.
Water in the compressor tank will cause serious corrosion to your air tools and should be drained daily
to avoid excessive water in your air supply. Dirty wet air rapidly shortens the life of your air tool.
If you are using an air tool on a hose over 25ft long it is advisable to increase the bore of the hose to
the next larger size available, i.e., 1/4" increases 3⁄8". This will ensure adequate pressure and volume
of air to power the machine.
