The coarse coalescing filter is utilized when low pressure drop or crude separation is required.
The coarse filter element is preferred in low pressure and vacuum application so that the efficiency of the compressor or pump is not sacrificed.
Also; the coalescing element will take out crude amounts of large liquid oil and water particles; specifically downstream of a compressor to protect a dryer.
The coalescing 1.0 micron coarse grade filter element features a unique vacuum-formed process.
It utilizes micro-glass fibers in raw form to create a seamless; depth-loading media.
Combined with a rigid fiber-binding epoxy; the filter element has great strength and high efficiency.
