The AirTAC GC400C15MLC2WG AirTAC F.R.L. Combination, G1/2 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400C15MLC2WG is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one air-preparation set for compressed-air lines. This configuration is built on the size 400 body with a G1/2 (BSPP) port. The filter element is the fine 5 um grade (code W) and the bowl drains manually, so an operator opens the drain when servicing. The regulator is the low-pressure type, suited to circuits that must not run at full standard setpoints, and a round gauge scaled in psi is fitted so the setpoint can be read directly. A mounting bracket is included and no reverse/check valve is fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options from 1/8 in up to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um fine filtration, gauge style and scale choices, and an optional reverse/check valve. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm the flow and datasheet figures for your application before ordering.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-C1 filter, GR400-C1 regulator and GL400-C1 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds spray guns and air-assisted applicators on a paint line, where the 5 um element helps keep water and particulate out of the finish and the lubricator mists oil to the air motor.
Conditions the air feeding clamp, push and lift cylinders on a packaging conveyor, with the regulator holding setpoint and the lubricator extending seal and bore life.
Prepares the air feeding tool-changer clamps, air bearings and pneumatic actuators on a machining centre, with the psi gauge giving operators a direct pressure readout.
Start with the port step: size 400 with a 1/2 in port sits in the upper half of the GC range (200/300/400/600), so match it against the air demand of the circuit - larger sizes carry larger ports and more flow. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. The 5 um element (code W) is the finer choice over the 40 um standard; pick it where downstream valves and cylinders need cleaner air. The manual drain means someone drains the bowl during service rounds - choose automatic or differential-pressure drain codes if nobody will be on site to do it. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is G (BSPP) on this unit; PT is the standard and NPT is available to order. The bracket is included, and the low-pressure regulator type should be checked against your working pressure - confirm its exact adjustment range with us, as it is not published as a single figure.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure and air demand and we will confirm the flow from the datasheet curves for this exact unit before you order.
The L code means the regulator in this GC400 set is the low-pressure type rather than the standard type, for circuits that operate below standard setpoints. The exact adjustment range for the low-pressure type is not published as a single figure in our sheet, so confirm it with us against your working pressure; the standard-type range is 0.15-0.9 MPa (20-130 psi) with this unit's manual drain.
