Question by: Brett M on Jan 2, 2026, 3:52 PM
Got a pneumatic setup running some air tools off a compressor line, how close to the tool should one of these lubricators actually be mounted?
Answer by: Customer Support on Jan 4, 2026, 12:34 PM
Closer is better, and that's not just a general rule. These lubricators are designed to be installed as near to the downstream application as possible so the oil mist actually reaches the tool before it settles out or dissipates. The further away you mount it, the less effective the lubrication gets. If you've got multiple tools pulling off the same line, you'd want to think about positioning carefully so each one gets what it needs.
