7. Filters
The optional Filters remove particles as small as 1 micron from the wash solution. If you
have purchased this option, your MART representative will have worked with you to
select a micron rating that best suits your washer's configuration and your applications.
When you purchase replacement filters, be sure the micron-rating is appropriate for your
washer's configuration: A filter with extremely fine pores could significantly increase the
pressure-differential and overload the capacity of the filter housing, affecting pump
pressure and flow rate.
7.1. Theory of Operation
The two filter types are:
·
Bag
·
Cartridge
Filter Types
Bag filters are generally recommended for 50-100 microns, although they can filter
down to 1 micron at lower flow rates. Bag filters are less expensive than cartridge
filters, easier to change, and re-usable. One filter at a time is inserted into the housing.
Bags are constructed of polypropylene, especially selected for reliable performance in a
hot, caustic environment.
Cartridge filters are rated for 1-50 microns. Multiple filters may be inserted into the
housing.
Filter housings have a swing-away lid. Filter elements are inserted into the housing
from the top. The housing lid is tightened with swing-bolts.
The following table shows micron comparisons to guide you in selecting filters.
