Seasoning with a Manual Operated Fan Damper

9. Monitor the face velocity. Open the fan damper a little at a time to keep
the face velocity at 30 − 38 m/min (100 − 125 fpm).
10. When the damper is fully open, or, after opening the fan damper slightly,
the face velocity no longer decreases as more powder accumulates on
the cartridges, start pulsing the filters. Set the pulse air pressure to
approximately 2.75 bar (40 psi).
NOTE:
Pulse the cartridges for a few minutes, then stop. Let powder build
up on the cartridges for a few minutes, until the pressure drop across the
cartridges increases. Start pulsing the cartridges again.
11. Continue pulsing the cartridge filters. Increase the pulse pressure
in 0.3 bar (5 psi) increments every 20 minutes until it reaches 4.1 bar
(60 psi).
12. Shut off the powder flow.
13. Close the slide gates.
14. Adjust the fan damper until the average face velocity is 30
− 38 m/min
(100 − 125 fpm) through all enclosure openings.
Seasoning with a Manual AMS System
Use the Seasoning with a Manually Operated Fan Damper procedure, along
with the following instructions.
Set the AMS controller to provide an average face velocity of 30 − 38 m/min
(100 − 125 fpm). Adjust the controller as powder builds up on the filters.
Start pulsing when you approach the setting limits, or when the face velocity
fails to decrease as powder continues to flow.
Seasoning with an Automatic AMS System
Use the Seasoning with a Manually Operated Fan Damper procedure, along
with the following instructions.
Set the AMS controller to provide an average face velocity of 30 − 38 m/min
(100 − 125 fpm). Start the powder flow. Although the AMS system should
automatically keep the face velocity constant, check it periodically. When
the fan rpm approaches the upper limits, start pulsing the cartridge filters.
Set the pulse air pressure to 2.75 bar (40 psi). The AMS system will
automatically reduce the fan rpm to keep the air flow constant. Continue
the powder flow and cartridge filter pulsing for approximately one hour.
