All Dimensions in Inches (mm)
Technical Data
Fluid: Compressed air
Maximum pressure
Transparent bowl: 150 psig (10 bar)
Metal bowl: 250 psig (17 bar)
Operating temperature*
Transparent bowl: 0° to 125°F ( -20° to 50°C)
Metal bowl: 0° to 175°F (-20° to 80°C)
* Air supply must be dry enough to avoid ice formation at temperatures below 35°F (2°C).
Start point (minimum flow required for lubricator operation): 1.5 scfm (0.71 dm 3 /s)
at 90 psig (6.3 bar) inlet pressure
Typical flow with 90 psig (6.3 bar) inlet pressure and 3.5 psig (0.25 bar) pressure
drop: 80 scfm (38 dm
3
/s)
Maximum recommended flow: 60 scfm (28 dm 3 /s). Air flows above 60 scfm
(28 dm 3 /s) create excessive air velocity, turbulence, and pressure losses. In
addition, the fog produced by the lubricator will wet out on the pipe walls and will
not be carried by the compressed air to the point of application.
Nominal bowl size: 3.5 fluid ounce (0.1 liter)
Manual drain connection: Will fit 1/8-27 and 1/8-28 pipe thread
Recommended lubricants: See Section ALE-29.
