Most standard breather caps are intended to cover the filler opening on a tank or reservoir to keep out rain and large solid particles. Most of these are only capable of stopping particles of about 100 micron or larger. Studies have shown that to have a significant effect on abrasive wear, particles of 10 micron or less must be kept out of the system. Watchdog breathers remove particles of 2 micron and larger before they cause the silent destruction of your equipment. Most importantly, standard filler/breather caps do not remove airborne water vapor that causes chemical and physical changes resulting in loss of additive performance, sludge, bacteria growth, and corrosion. Watchdog breathers remove water vapor before it enters the tank or reservoir.
