Castair C-LS34 — 3/4" Air Line Lubricator, 250 PSI, 160 CFM
The C-LS34 is a 3/4-inch NPT standard-size air line lubricator from Castair. It sits between the 1/2-inch C-LS12 and the 1-inch C-LS10 in the Castair lubricator lineup — the right unit for shops running 3/4-inch main lines or branch lines feeding multiple lubrication-dependent pneumatic tools simultaneously.
At 160 CFM and 250 PSI maximum, the C-LS34 delivers adequate oil mist volume to keep multiple air tools properly lubricated at a 3/4-inch junction or main line. The 11-ounce reservoir handles longer operating intervals between refills compared to the smaller 8.5-ounce bowl on the 1/2-inch unit.
What This Unit Does
- Controlled Oil Mist: Adjustable oil feed rate introduces lubrication into the air stream for downstream pneumatic tools that require in-line oil.
- 11 oz Reservoir: Larger capacity than the 1/2-inch unit — extends the time between refills on higher-flow or higher-demand installations.
- 3/4" NPT Female Connections: Fits 3/4-inch pipe and fittings directly — no adapters needed.
- 250 PSI Max / 160 CFM: Handles 3/4-inch main lines and multi-tool branch feeds.
System Placement Note
Install the lubricator last in the FRL sequence: filter → regulator → lubricator. The lubricator must come after filtration and regulation — oil injected upstream of filters will foul the filter elements. Install at point-of-use drops feeding tools that require lubrication rather than on a shared main line where some equipment needs oil-free air.
