Anyone ever use inline air filters in there systems?
I’m not sure why you’d want to unless you intend running air-tools or turbine powered devices. The main danger of debris ingestion is at the compressor intake (which needs the filter).
The same really goes for water traps. The tank will trap all the moisture as the air cools after compression (which the tank drain will take care of). Any residual moisture will just get blasted out of the horns. Again, unless you running a device which is sensitive to moisture, there’s not point in adding complexity.
I use a CoilHose coalescing filter with a metal bowl, sightglass, and drain (to which I have a manual ball-valve and drain tube connected). However, I’m not running an electric compressor; I have a modified York 210L EDC (engine driven compressor) under the hood that has an oil sump and is splash lubricated with 30weight motor oil. That’s why I need such a filter in line (after my LoadGenie check/unloader valve and before the rest of the air system) – to keep oil out of the air system. (The York will consume ~1oz of oil per hour of runtime, most of which would end up in the air system if unfiltered.)
As an added bonus, the coalescing filter also snags/filters water vapor – and I’ve yet to drain more than mist from my tanks.
