Frequently Asked Questions
FILTERS, REGULATORS, LUBRICATORS
- Can someone change from a manual to an auto drain on an 18/28 series filter in the field?
- How do I properly size and determine feasible application of a filter, regulator or lubricator?
Basic information one should know is pipe size, inlet pressure (PSIG), flow (SCFM) and for regulators, the regulated pressure range. The temperature of the air stream and the ambient temperature, and whether or not any incompatible chemicals, solvents, vapors, or oils are present in the atmosphere or air stream is also important.
One can estimate flow by adding the usage of all the machinery being supplied downstream (point of use). It is always good to be a little conservative, and add flow for users who might occasionally blow down equipment, or otherwise exhaust air for some reason. You can also size Wilkerson products by using the performance charts that are in each product section of our catalog 9EM-TK-190 (8/2003). It is always good design to have no more than a 2-3 PSI pressure drop, at maximum rated flow, with a clean element.
Oversizing filters costs you a little extra in purchase price; undersizing filters costs you in wasted energy
(high pressure drop) over the entire life of the filter in the system!
