AFS : ADJUSTABLE AIR FLOW SYSTEM
How does it work ?

For 100% air capacity:
1st stage double acting cylinder raises atmospheric air to 4 to 5 bar achieving the most important pressure ratio from 1 to 4 to 5 bar.
At full load 1st stage double action cylinder produces 100% of rated capacity to provide 100% air to your application.

For 55% air capacity:
1st stage double acting cylinder compresses air upward only.
AFS automatically unloads the lower part of the cylinder to match air flow required in the system.
Comparaison:
AFS : Adjustable air-flow system : savings in figures
Savings are immediate and start from day one.
- Savings are immediate and start from day one
- Up to 45 % savings on the kW power at the shaft during half load
- Up to 5 % savings on apparent power
