Cartridges may also be serviced from above using a top plate larger
than the tube sheet hole. In this configuration the cartridges are
sealed from above with hold- down clamps.
The horizontal cartridge configuration is more likely to be used
only for extreme headroom restrictions, as more than one row forces
the dust to recycle if it has to move down onto another row.
Traditional cartridges are 12-3/4" diameter and 26" long,
with 226 square feet of a specially treated paper media. They are
frequently double long (52") and sometimes longer if the velocity
restrictions in the dirty chamber will permit.
Sometimes pleated bags, usually 6" diameter with lengths to
84" are referred to as cartridges, especially when retro-fitted
into an existing bag type pulse jet collector. With eight times the
cloth area per unit of length, they are furnished for increased the
air volume capacity in a given housing. The allowable air velocity
within the dust collector's dirty air chamber will determine the
length and type of pleated bag.
Large access doors are a must, and we furnish them with 6"
ball handles for easy removal of the cartridges without the use of
tools. The clean air plenum has a large access plate with two view
ports that open for quick inspection.
An exhaust fan (shown mounted on top in the picture) with motor,
drive and guards may be mounted on the top or any side. If the fan is
not mounted on the dust collector, interconnecting duct work may be
provided to floor or platform level. Sound attenuation, vibration
isolation, control dampers and starters are available.
The dirty air inlet may be in the hopper as shown or introduced at
a higher level into a decantation chamber. Clean air may exit from the
top or side.
Collected dust is deposited in the pyramidal hopper with a normal
side slope of 60 degrees to the horizontal. More or less slope
is provided as required.
The pulse timer with solenoids is mounted on any side, complete
with a differential pressure gauge that may control the timing cycles
if desired. These items may also be incorporated into the fan starter
enclosure, either of which may be remote from the dust collector if
The compressed air header is complete with diaphragm pulse valves,
a liquid filled pressure gauge and a petcock drain. The pulse system
is piped, wired and tested at the factory.
The assembly is shipped ready to run when the size permits.
Explosion ports may be fitted to the body of the collector. Hoppers,
rotary air-locks, drum connections, legs, ladders, and platform
structures are all available. Stainless steel construction or special
coatings are other options.
These package units are available from one traditional 26"
long cartridge with 226 square feet of media (552 CFM at 2:1 air to
cloth ratio) to 64 double long cartridges with 28,928 square feet
total (57,856 CFM at 2:1 air to media ratio). Special media, such as
spun bond hydro and oleophobic polyester, will have less surface area
