4. Connect the inlet tube of the filter chamber to the outlet of the cyclone
separator.
4-3-7 Installing the Filter Chamber Shroud
The cloth filter shroud is mounted to a ring on the underside of the filter
chamber stand. It reduces housekeeping duties around the filter chamber by
preventing dust from being stirred up when the dust and fines are discharged
from the VFC filter chamber. The dust container below the shroud is customer-
supplied—the standard 24” (61 cm) clearance stand is designed for use with a
5-gallon (19-liter) pail, and the optional 38” (96 cm) clearance stand is
designed for use with a 55-gallon (208-liter) drum.
1. Insert the filter shroud support wire into the slotted hole in the middle
of the cloth filter shroud. Use supplied hardware to secure.
2. Slip the filter shroud over the retaining ring located on the bottom side
of the filter stand mounting plate. Secure it with the worm clamp
provided.
3. Place the dust container you’ve supplied below the filter chamber
stand and insert the filter shroud.
4. On standard 5-gallon (19-liter) pails, the filter shroud should be
trimmed to project about one half of the way into the container. Don’t
trim the filter shroud on 55-gallon (208-liter) drums. Secure the
drawstring on the shroud around the drum, making sure the open end
of the shroud hangs freely inside the drum.
5. Make sure the operation of the counterweighted flapper dump valve is
not obstructed in any way by the filter shroud.
CAUTION! Do not obstruct the filter shroud in any way.
Empty the dust container before
the dust level obstructs the end of the filter shroud.
4-4 Making Compressed Air Connections
Note: If the system you specified uses a vacuum unit with non-reversing valving for
blowback, you must connect the vacuum unit to a source of clean, dry, lubricated
compressed air with an operating pressure of 80 psig (551.6 kPa/5.52 bars).
CVP/CPP Systems
CVP/CPP systems do not require compressed air connections at the pumps.
