Cartridge Filter Seasoning
New cartridge filters must be properly seasoned. If new cartridge filters are
not seasoned, their performance and life can be dramatically reduced.
Cartridge filter seasoning is accomplished by introducing virgin powder to
the afterfilter through the cyclone inlet duct. Seasoning requires a minimum
of 4.5 kg (10 lb) of virgin powder for each cartridge filter in the afterfilter.
For example, the standard 11250 cfm system uses 15 cartridge filters, and
therefore requires 67.5 kg (150 lb) of virgin powder for the seasoning
procedure.
WARNING: Wear protective clothing, safety goggles, and approved
respiratory protection whenever handling powder or performing
maintenence or cleaning procedures. Follow the personal protection
recommendations included on the Material Safety Data Sheets for each
powder used.
1. Turn on the exhaust fan.
2. Measure the initial average air velocity across the booth part openings
using a hand-held velometer.
3. Record the cartridge filter and final filter static pressures.
4. Open the transfer pan and the cyclone access doors.
5. Open the AeroDeck and gradually dump the virgin powder into the floor
duct.
6. Note the cartridge filter static pressure displayed on the pressure gauge.
If the pressure is less than 3-in. wc, add more powder until the static
pressure reaches 3-in. wc.
7. Close the cyclone access doors and transfer pan.
8. Record the average air velocity across the booth part openings using a
hand-held velometer.
9. Record the cartridge filter and final filter static pressure.
