Where to buy hydraulic filter element in right way

When comparing filter elements, the better filter is the one that will achieve and maintain the required or targeted fluid cleanliness level (at the lowest cost).

One of our readers wrote me this question:

"We are evaluating filters for a contract and I had the suppliers give me the Beta ratios for the elements they propose to supply. The problem is one company has given me Beta ratios for 2 and 11 microns, and the other company, 6 and 20 microns, i.e.:

Company A's filter is Beta2 = 2 and Beta11 = 20

Company B's filter is Beta6 = 2 and Beta20 = 75

My question is which filter is better?"

Keep in mind though, it is unwise to upgrade existing filter housings with finer, more efficient elements, without first checking that the increase in pressure drop created by the new filter-element is not going to cause problems. Like putting the filter on bypass, for example.

As with most maintenance issues, the best approach is to start with the end in mind. In this case it means:

1. Establishing the required or targeted fluid cleanliness level for the machine or system;

2. Specifying a minimum, filter-element blocking size and Beta ratio that can be realistically expected to achieve the desired cleanliness level;

3. If this involves an upgrade of the elements in existing filters housings, flow rates and pressure drops must be checked to confirm the higher filter specification won't cause any problems.

4. And then the filter supply contract can be released for commercial tender.
