A major bearing manufacturer has stated that bearings can have an infinite life when small particles are removed from the lubricant. Hydraulic fluid will last three, even four times as long if water vapor is kept out of it. A power outage when a transformer fails is staggering. A Watchdog part number 39102 will hold up to a pint of water and will filter out 2 micron abrasive particles. The price of a breather is well below the cost of changing hydraulic fluid three times, or rebuilding a gearbox or cylinder, or having electrical shorting in a transformer.
