Heavy-Duty Mist Lubrication for Compressed Air Lines
The Speedaire 4ZL61 adds a controlled amount of oil to compressed air so that downstream air tools, cylinders and valves stay lubricated as they cycle. It installs in the main air line with 1 in female NPT ports, handles flow up to 275 cfm and is rated for working pressure up to 250 psi. An integral flow sensor keeps the oil-to-air ratio steady as demand rises and falls, so the feed does not need constant readjustment.
How It Delivers Oil
This is a mist lubricator. A mist unit is suited to feeding one tool or device close to the lubricator, with pipe runs of roughly 15 to 20 feet. Oil feed is set with a screwdriver adjustment, and the transparent nylon sight dome lets you watch the drip rate while the system runs. The 32 oz metal bowl has a sight glass for checking the oil level and can be refilled while the line is under pressure. A drain is included.

Installation and Use
Mount the lubricator after the filter and regulator in an air preparation set, with air flowing left to right through the body. Fill with ISO VG 32 oil and set the drip rate to match the tools being fed. Confirm the 1 in port size, overall height of 12-7/16 inches and the 41°F to 175°F temperature range against your installation before ordering. In a woodworking shop, a lubricator of this size can serve air-driven equipment such as pneumatic clamps, feeders and cylinders that call for lubricated air; check each device's manufacturer guidance, because some components are designed to run on dry air.
