Installation of Snapband Retainers for Top Load Filter Elements
NOTE : A snapband retainer has been shipped with every top load Filter Element. If you do not
have these snapband retainers, call your representative immediately so they can be sent to you for proper
installation.
5. Pinch the snapband retainer in the center to form a figure “8” (Figure #6).
6. Bend the loop slightly and place the retainer under the molded lip of the top flange of the filter element.
This shallow lip prevents upward movement of the snapband retainer after proper installation (Figure #7).
7. With the snapband retainer held against one side of the filter element top interior (Figure 7), slowly allow
the retainer to expand into the recessed area between the lip rim and the three interior post stops.
8. The snapband retainer should fit snugly between the lip rim and the vertical post stops
(Figure 8). Be sure the snapband retainer is level and not installed crooked. A correctly installed snapband
retainer will help prevent any potential leakage at the tubesheet and keep the filter element firmly in place.
Operation Procedures for Top 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 - 0.15 seconds.
• The pressure of the compressed air at the baghouse air header should be set and adjusted as follows when
using 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.
• 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.
