Compressed Air
Nordson recommends using dry, controlled and non-lubricated compressed
air.
Operating with Non-lubricated Compressed Air
When an application head is connected to a compressed air system in
which the compressed air has previously been lubricated, simply ceasing to
lubricate the air is not sufficient. The oil remaining in the compressed air
supply will reach the solenoid valves and the control modules and wash out
the lubricant/oil from these parts, substantially decreasing the lifetime of the
units.
NOTE:
It must be ensured that the compressed air supply to the application
heads has been converted to absolutely non-lubricated operation.
NOTE:
No oil from a possible defective compressor may be permitted to
penetrate the compressed air supply.
NOTE:
Nordson will assume no warranty/liability for damage resulting from
unpermitted, temporary lubrication.
Conditioning Compressed Air
The quality of the compressed air must be at least class 2 as stipulated by
ISO 8573

Pneumatic Connections
1. Connect customer’s air supply to to the inlet of the air conditioning unit.
Maximum air pressure:
10 bar
1 MPa
145 psi
2. Connect control modules to the air conditioning unit.
3. Set control air pressure:
Approx. 5 to 6 bar
Approx. 0.5 to 0.6 MPa
Approx. 72.5 to 87 psi
NOTE:
The exact pressure must be determined for each application.
