Information
Changing Filter Bags
Keep a set of spare filter bags in reserve at all times. Examine
the bags in service periodically and replace them with genuine
Spencer filter bags when visibly worn. Also look for leaks, which
are signalled by dirt on the outside of the bags or on the bag
head or by dust in the discharge airstream.
1. To install a new filter bag, compress the spring collar at the
bottom of the bag.
2. Insert the compressed spring collar into the bag head
opening and allow it to resume its original shape.
3. Pull up on the bag to be sure it is properly seated.
The recess in the spring collar must be at the bag head
opening. (Entire collar should not be below bag head.)
4. Install buckle on the narrow tab of filter bag and attach to
hook on shaker plate. Pull on tab end to remove slack.
5. If filter bags are equipped with ground wires, connect them
to ground lugs on the tube sheet near the bag collar.
Note: Also insure that a properly sized ground wire is
attached to the ground boss on the exterior of the separator
(for separators with grounded bags only).
In addition to standard cotton sateen filter fabric, various other
materials are available in Spencer replacement bags. They
offer specialized properties suited to adverse conditions such
as dampness, abrasion or chemical attack.
Special-purpose filters are also available, such as optional
HEPA (High Efficiency Particulate Air) filters with a filtration
efficiency of 99.97% at 0.3 micron particle size. For recommen-
dations, consult your Spencer Representative.
