frequently with increased dusting conditions. Since filter cleaning action is directed to an
individual filter bag, remaining filter bags are on-stream, continually filtering conveying air.
ACA Series filter chambers are shipped completely assembled to reduce customer installation
time. Several mounting arrangements are available, depending on the mounting adapter
supplied with the unit.
ACA filter chambers are used with several different sizes of vacuum hoppers, depending on
the mounting adapter supplied with the unit. Typical hopper sizes range from 0.8 cu. ft. to 6.0
cu. ft. (22.7 liters to 169.9 liters); smaller hopper installations are also possible. You must
install a bottom flange adapter when mounting the filter chamber to the vacuum hopper. The
adapter increases overall height of the filter chamber unit; this may affect where you install
the unit.
Installing Vacuum Receivers and Inventory/Vacuum Receivers
Vacuum uses one of three mounting systems: flange, suspension, or silo mounting. Vacuum
receivers and inventory vacuum receivers use flange mountings only.
• Remove all rubber banding and any other packaging materials from around the flapper
dump valve before installation for proper operation.
Complete the vacuum and material tubing to the vacuum receivers. Final connections are
usually made with flexible hose.
Note: On single line Y systems, you must install a check valve on the material inlet of
each hopper.
Installing the Safety Filter
Use the following procedure to install the safety filter:
1. Place the safety filter in the conveying system directly before the vacuum pump.
2. Using 7/16”, Grade 5 or better hardware, secure the filter in place:
Wall Mount. Use the mounting flange to secure the filter to the wall.
Floor Mount. Bolt the floor stand to the ground.
Pump Mount. Bolt the pump and stand to the ground. Pump-mount is only available with
SPC pumps.
WARNING! Make sure all screws are strong enough to hold the weight of the filter.
• Connect the vacuum line to the filter chamber’s inlet tube (A). Use a hose clamp to
secure the flexible hose.
• Connect the vacuum pump line to the outlet tube (B). Use a hose clamp to secure the
flexible hose.
