SMC NAL800-N12 Lubricator is a large-flow airline lubricator that injects a controlled amount of turbine oil into compressed air to lubricate downstream pneumatic components. The model uses a 1-1/4 in NPT connection (NAL800-N12), includes a site gauge and drain cock, and employs a polycarbonate bowl with a 440 cm3 oil capacity. It accepts up to 1.5 MPa (220 psi) of supply pressure with a maximum operating pressure of 1 MPa (145 psi) and a service temperature range of 5–60°C (41–140°F), with turbine oil ISO VG32 recommended as the lubricant. Related variants in the same family include NAL800-N14, which uses a 1-1/2 in NPT port.
