How to Protect the Water Filter in an Air Compressor with Extra Coiled Air Hose
posted on by

Usually the water filter in my air compressor line has sufficient capacity to keep the air dry, but when I’m spraying a really large project, it fills up rapidly. In these situations, here’s an easy modification that reduces the frequency of draining the filter—it’s actually an old auto-body shop trick I’ve adopted for woodworking. I install an extra 25-ft. air hose between the compressor tank and filter, coiling it flat on the floor. This intermediate hose cools the air from the compressor and collects some of the condensation before it reaches the filter. It’s important that this hose remains flat on the floor to prevent any large slug of water from carrying over.
