A coalescing element is a fine depth media. Hand it bulk water, rust and pipe scale and it blinds, the pressure drop climbs, and you replace a costly element months early. Fit a 40 micron particulate filter upstream, such as the \u003ca href=\"\/products\/parker-prep-air-ii-06f-compact-particulate-air-filter\"\u003e06F in the same body size\u003c\/a\u003e, and the coalescer will do what it is rated to do for as long as it should.\u003c\/p\u003e\n\u003ch3\u003eReading the pop-up indicator\u003c\/h3\u003e\n\u003cp\u003eThe clear dome on top is a differential pressure indicator and it is the only honest way to know when the element is done. Coalescing elements do not look dirty when they are finished; they look fine and quietly cost you 10 PSI. When the button has risen, change the element, regardless of how long it has been in. Note the trade-off: fitting the indicator drops the maximum working pressure to 150 PSIG and the temperature ceiling to 125 degrees F, so on a 175 PSI system you want the version without it and a gauge either side instead.\u003c\/p\u003e\n\u003ch3\u003eDraining\u003c\/h3\u003e\n\u003cp\u003eA coalescer collects liquid oil, not just water, and that sump will not evaporate. The twist drain is manual, so it needs a person or it needs replacing with an automatic. Whatever comes out is oily water and in most jurisdictions it is not something you pour down a drain.\u003c\/p\u003e","brand":"AirComParts","offers":[{"title":"1\/4 in.
