The AirTAC GC30010MLF2WK AirTAC F.R.L. Combination, PT3/8 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 PT3/8" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30010MLF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, a regulator and a lubricator supplied as one set. This configuration is built for 3/8 in PT-threaded ports, filters the air down to 5 um, and drains the filter bowl manually. The regulator is the low-pressure type, a square pressure gauge scaled in psi is fitted, a reverse/check valve is included, and a mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and at this size the filter and lubricator bowls are polycarbonate (PC).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus drain, filter grade, gauge scale and regulator-type choices to match your circuit. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF300-10 filter, GR300-10 regulator and GL300-10 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.

Mounted at the inlet to a machine's actuation circuit, this unit filters the air to 5 um before it reaches directional valves and cylinders, holds the circuit pressure with the low-pressure regulator, and meters oil mist to keep the actuators lubricated through the shift.
Installed on a 3/8 in air drop serving lathes, mills or drill presses, the combination cleans the shop air, sets the working pressure for the clamps and air tools on the bench, and lubricates the tools - with the reverse/check valve holding the setting if the main supply dips.
Feeding the pneumatic cylinders and air-operated grippers on a packaging or cartoning line, this set conditions the supply at the line drop: 5 um filtration protects the valves, the regulator holds a steady low-pressure setting for delicate product handling, and the lubricator services the actuators.
Size 300 with 3/8 in PT ports sits in the middle of the GC range - a step up from 1/4 in drops without moving to the 1/2 in class. Match the size step to the air demand of the tools and cylinders on the circuit. The 5 um element (code W) is the finer option over the 40 um standard; choose it where downstream valves and cylinders need cleaner air. Manual drain means the filter bowl is emptied by hand, so pick automatic or differential-pressure drain if the unit will be mounted where it is hard to reach. The low-pressure type regulator (code L) is intended for low-pressure circuits; its exact adjustment range is not published in the material we hold, so we confirm it on request. The gauge is the embedded square type scaled in psi (MPa and bar scales are available), a reverse/check valve is fitted, and PT is the standard thread with G and NPT as order options.
Before ordering, send us your required flow and operating pressure: flow for the GC300 is published as curves, not a single rating, so we will confirm the sizing against your application from the datasheet.
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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC300 as curves, not as a single rated figure, so we do not quote a number here. Send us your air demand and working pressure and we will confirm from the datasheet whether this size and its 3/8 in PT ports suit your application before you order.
L marks the low-pressure type regulator in this combination. It is intended for circuits set at lower pressures than the standard type; the exact adjustment range for this variant is not published in the material we hold, so we will confirm it on request. The rest of the code decodes as: 300 size, 3/8 in PT ports, M manual drain, F square gauge with psi scale, W 5 um filter element, and K reverse/check valve fitted.
