Technical note:
Subject: Burr King Filter PAK 4000, filters
October 2000
The Burr King Filter PAK 4000 is a closed loop compound delivery system that incorporates a high
quality polyester felt membrane filter. The filter is rated at 25 gallons per hour, well over the necessary
flow rate for most vibratory systems. The filter is also rated for a pressure head of 12 feet (6 PSI).
Various filter mesh sizes may be used. The fluid moving through smaller mesh size filters will contain
smaller particulates than will fluid passing through larger filter mesh sizes. The following data is based on
Burr King P-20 ceramic media and serves as a guide for filter mesh size selection.

* Filter PAK 4000 units include two 15-micron filters as standard.
Note 1: Human hair is approximately 0.003 inches in diameter. Filters are rated by the size of particle that will, with
high probability, be trapped. This also means that a small percentage of larger particles will escape and stay in
solution.
Note 2: Effective life is the point in time when the filter flow rate drops to 50% of rated value. Effective life will
vary greatly depending on the media used, flow rate metered, material being processed, and the volume and energy
of the vibratory system.
Burr King recommends 15-micron filters for most ceramic media applications. We recommend 50 or 100
micron filters for most plastic media applications. When greater fluid clarity is required, or fewer residues
remaining on parts is desired select a smaller filter mesh size. Compounds such as anti-rust and soaps will
pass through the filters and remain in solution. The filters will trap compound additives such as plastic
anti-stick beads. Remember that smaller mesh size filters will require more frequent changes.
Filters are available from Burr King by individual mesh sizes in packs of 5, 10, and 25 filters/pack.
