Operation Procedures for Bottom Load Collectors
• Leave the timer adjustments set as specified by the baghouse manufacturer until operation stabilizes (usually
24-48 hours). We also recommend a precoating agent such as Neutralite ® utilized to help establish an initial
control layer. Once operation has stabilized, the time interval between pulses should be adjusted daily until
the longest off-time possible has been attained without exceeding the designed differential pressure.
Excessive pulsing will lead to shortened filter life. Set the pulse on-time at 0.06 - 0.10 seconds.
• The pressure of the compressed air at the baghouse air header should be set and adjusted as follows when
using cartridge filter elements:
The initial setting should be 60 psi. Increase only if the differential pressure cannot be maintained. Then
increase in 5-10 psi increments until it reaches a maximum of 90 psi. If the pressure must be increased further,
contact
Camcorp.
• Only dry compressed air should be supplied to the baghouse cleaning system.
• All inlet ducts should be equipped with baffles or deflector plates to prevent high velocity impingement of
the particulate on the filter surface. Dust should never be allowed to build or stand in the hoppers.
• Verification of airflow should be completed after startup of the baghouse. In some cases, the airflow will be
increased if proper airflow dampering or other method of controlling airflow is not utilized. Set the dampers
or fan speed to the minimum required airflow at the ventilation point. If not controlled, increased pressure
drop may occur due to increased grain loading and high gas velocity between filter elements.
5. Center the clamp in the groove in the urethane top.
Using a nut driver, hand tighten the clamp.
Care should be taken when tightening the clamp:
• Do not over tighten. Over tightening may cause a
cutting of the urethane.
• If the urethane material extrudes into the clamp band
notches or around the edge of the clamp, over tighten-
ing has occurred.
• Use of “lined” clamp is recommended, which protects the
urethane from damage. Maximum width of the clamp
band is 9/16”.
After tightening, you should not be able to rotate the filter ele-
ment by hand. Make sure the filter elements hang plumb and
are not touching each other or the collector wall (Figure #4).
