Compressed Air

E 2020 Nordson Corporation
To achieve maximum hot melt output, the melter must be connected to an air
supply that is capable of providing 6.2 bar (90 psi) of dry, non-lubricated air.
The actual pressure required for the melter to support your manufacturing
process will depend on such factors as the type of hot melt and applicator
you are using and the required dimensions of the hot melt bead.
NOTE: The operating air pressure range for the melter is 0.69 to 6.2 bar
(10 to 90 psi). Operating the melter with air pressure less than the minimum
may cause the pump to function erratically.
Air consumption during operation:
Depending on the type of pump being used, follow these specifications for air
consumption:
Standard Double-Acting
2.0 SCFM at 60 psi and
1.2 lb/min
(56 l/min at 4.1 bar and
0.54 kg/min output)
Air consumption with fill system by transfer rate:
17 SCFM at 3.4 bar (50 psi) to transfer 105 kg/hr (232 lb/hr) with
S
a 4 m hose at a 4 m rise
22 SCFM at 4.1 bar (60 psi) to transfer 113 kg/hr (248 lb/hr) with
S
a 9 m hose at a 4 m rise
30 SCFM at 6.2 bar (90 psi) to transfer 91 kg/hr (200 lb/hr) with an
S
18 m hose at a 4 m rise
Average: 1.3 SCFM for a complete system [melter, 4 m transfer hose,
S
4.1 bar (60 psi)] operating at 11 kg/hr (25 lbs/hr) adhesive output
NOTE: Nordson recommends that an isolation valve be installed in the plant
air supply line just before the melter for safety and maintenance purposes.
