5.4 Compressed Air Requirements
A reliable and consistent supply of clean dry compressed air is essential for proper operation.
5.4.1
Air Filtration
Although the machine contains its own internal air supply filtration system it is recommended the
compressed air supply should have external filtration in the line feeding the machine, both a
standard water trap (sintered bronze filter) and also a coalescing filter (for oil in air).
The air must be dry and free of oil and moisture (normally a symptom of older, worn out
compressors).
5.4.2
Air Compressor / Air Supply
The air requirement is a minimum of 120 l/min (4.5cfm) Free Air Delivery (FAD) at 75psi pressure.
This normally means the compressor must be a belt drive model or if a direct drive it must have a
motor power of 2.5HP or greater.
5.4.3
Air Hose & Fittings
The air hose must also be of sufficient size (3/8"/ 10mm minimum) to supply the machine.
The machine is supplied standard with a Nitto-style male air fitting. If you don't use Nitto fittings in
your workshop you will need to replace this fitting.
