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?
When should I use an AtoMist lubricator instead of an EconOmist Lubricator?
The AtoMist sends finer oil aerosol particles downstream than does the EconOmist lubricator. These oil particles will stay suspended in the airstream much longer than the larger economist droplets. Therefore, it is better to use the AtoMist when the lubricator cannot be placed within about 10-12 feet of the application, or if the air flow in your system is intermittent.

The ratio of drops of oil in an EconOmist is 1:1; that is, for every drop you see in the sight adjustment dome, you get one drop of atomized oil in the air stream. For the AtoMist, the ratio is 33:1. A good starting point for lubrication is about one drop of oil for every twenty cubic feet of air flow.
