Operating tips for your FilterPAK 4001
1. During the first few hours of operation after the installation of new media:
• The drain tube from the vibratory chamber to the FilterPAK 4001 may plug. This is a consequence of the new media sloughing
off edge particles that may not gravitate into the filter bag. Should you observe particles collecting in the clear drain hose tilt the
hose to allow the particles to flow into the FilterPAK 4001. Alternately, disconnect the hose and allow the particles to escape into
a bucket for disposal. Reconnect the hose. If the hose becomes fully impacted the FilterPAK 4001 will pump dry prematurely and
the available fluid will collect in the vibratory chamber. If this occurs it will be necessary to stopper the chamber before removing
the clear drain hose to prevent spillage. It may also be necessary too forcibly dislodge the hose impaction using a rod or similar
device.
• The filter bag may require changing after 2 to 4 hours of operation or less if plastic media is in use. This is a natural
consequence of “break-in” of the media. Larger, coarser media will create more initial debris than will smaller finer media.
• After media “break-in” change the filter at regular intervals (see previous discussion on page 1). Keeping the filtration system
clean will pay dividends in media life, reduced cycle times, and part cleanliness.
2. Use a 5-gallon bucket or similar container to place exhausted filters into after removal from the FilterPAK 4001. Doing thus will
provide you a handy way to avoid spillage since the exhausted filter will have some liquid trapped, and also provide a place for the
filter to dry in preparation for disposal. It is not uncommon to trap two or three pounds of sludge in the filter.
3. Mix your water and compounds (soaps) in a separate, clean bucket. Add the fluid to the FilterPAK 4001 (or to the vibratory
chamber) as required. Doing thus will assure that you maintain the proper ratio of compound to water.
4. Do not allow the pump to sit in a layer of collected sludge in the FilterPAK 4001. The sludge will harden over time and damage
the pump. Periodically, take your FilterPAK out of service and thoroughly clean out all sludge from both chambers.
5. Periodically check the pH (acidity/alkalinity) of the vibratory fluids. As a general rule deburring media prefers a pH of 8 to 11
(alkaline) when used on steel, aluminum, cast iron, copper, etc. Adding the recommended mixture of vibratory soap to water that is pH
neutral (7.0) will typically raise the pH to the recommended 8 to 11 range. As oils and other contaminants are added as a natural
consequence of the deburring process the pH may drop below the recommended level. This may result in accelerated rusting and/or
other staining of your material. Should this happen replace the vibratory fluid with fresh fluid mixed per manufacturer’s instructions.
There are several methods available for measuring pH. Electronic meters are the most accurate and the most expensive. Litmus paper
is inexpensive and suitable for this purpose. Purchase litmus paper at drug stores, chemical supply houses, or through your local
industrial supply.
6. DO NOT USE FLUIDS OTHER THAN WATER (with approved soaps) in the FilterPAK 4001. Doing so may create a fire or
explosion hazard resulting in serious injury and/or property loss. Additionally, fluids other than water and recommended soaps may
attack the urethane liner of the vibratory chamber and significantly shorten its service life. Burr King vibratory chambers are
covered by warranty that is void if unapproved fluids are used.
