IMI Norgren

Norgren Oil-Fog Lubricators

- Flow sensor design (except 10-028 and 10-076) provides a nearly constant oil/air ratio over a wide air flow range.
- Tamper resistant device can be installed on oil-feed adjustment to resist unauthorized adjustment.
- All around (360) visibility of the sight-feed dome simplifies installation and adjustment.
- Optional 1-quart reservoir available on the L74.
- The optional 2- and 5-gallon reservoirs used on the L17 lubricator are rated to ASME Pressure Vessel Code, Section VIII.
- Can be filled under pressure, except for optional bidirectional models and models with 2- and 5-gallon reservoirs.

Note: Do not use L17, L72, L73, L74 lubricators, and the 10-028 lubricator downstream of frequently cycling directional control valves. Use the optional bidirectional Oil–Fog Lubricator for such conditions.
