AIR PRESSURES
1. Air requirement recommendations:
· A minimum of 100 psi on main air.
· 20 - 30 CFM for chopper systems
2. Material pump: 30 - 50 psi
3. Catalyst Atomizing Air: Catalyst atomizing air should be balanced generally between a range of 15 -
25 psi. It should be low enough to reduce catalyst over-spray and high enough to atomize catalyst
efficiently. This allows user to attain and operate under optimum efficiency.
TESTING SPRAY PATTERN
Testing of your spray pattern should be performed away from original part. Use paper or cardboard to
check the following:
· Spray pattern width and output
· Catalization
· Spray pattern definition (fingers and tails):
· Adjust as necessary with the “MVP Air Assist” adjustment screw to give the finest pattern
available by eliminating fingers and tails.
· Check glass distribution
After completion of the above procedures, you may now confidently use your MVP system
