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).
We highly recommend the Weldclass Platinum Z-20 air filter – see information below.
The air must be dry and free of oil and moisture (often 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.
Dry and clean compressed air is extremely critical for successful plasma cutting. Any humidity (moisture) or
particle (dirt/dust) content in the compressed air supply will; increase the likelihood of torch & machine
malfunction, accelerate parts consumption and affect cutting capacity/performance.
The air regulator/filter supplied with the CF-45P machine provides the minimum level of filtration.
However, we strongly recommend the WELDCLASS PLATINUM Z-20 high-performance air filter, available as
an optional accessory from your Weldclass distributor. This attaches to the inlet of the existing
regulator/filter and provides excellent filtration down to 1-micron.
