The AirTAC GC40010MLF2WK 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 GC40010MLF2WK is an AirTAC GC400 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is sized for 3/8 in PT ports, with a 5 um filter element (the finer of the two published grades), a manual bowl drain, a low-pressure type regulator, an embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. The filter removes water and particulate, the regulator holds your set downstream pressure, and the lubricator meters oil mist into the air line for downstream pneumatic components.
This is a genuine AirTAC part. The GC series is published in sizes 200, 300, 400 and 600 with a choice of port sizes and G, NPT or PT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and gauge scale options. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us and we will 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: GF400-10 filter, GR400-10 regulator and GL400-10 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.

Point-of-use air preparation at a spray booth or finishing line, where the 5 um element protects the application from water and particulate, the regulator holds a steady set pressure, and the lubricator conditions air for downstream valves and cylinders.
Feeding the cylinder and valve bank of a carton former or case packer, where one three-unit set cleans, regulates and lubricates the whole machine supply at a 3/8 in connection, and the check valve holds the circuit against backflow.
Supplying suction and gripper circuits on a palletizing robot cell, where the low-pressure regulator suits lower set pressures, the psi gauge gives operators a local reading, and oil mist keeps actuation components running through long shifts.
Start with the port step: the GC series runs in sizes 200, 300, 400 and 600, and the 400 size carries the 3/8 in port in this code - step up or down if your line size or air demand differs. Choose the drain to match maintenance practice: manual drain (this unit) needs someone to open the bowl, while automatic and differential-pressure drains discharge condensate without attention. Filtration is 40 um standard or 5 um (code W, fitted here) where finer particulate protection matters. The gauge is an embedded square gauge; scale 2 reads psi, with MPa and bar scales available, and an external round gauge is optional. Thread is PT as standard, with G (BSPP) and NPT as order options; a mounting bracket is included and a reverse/check valve is fitted.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, and this unit is a low-pressure type regulator whose exact adjustment range is not published on the sheet we work from. Ask us to confirm the flow curve and regulator range against your application before you order.
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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and the equipment you are feeding, and we will confirm the relevant flow curve from the datasheet for this 400-size, 3/8 in unit before you order.
The M in the code selects a manual bowl drain: condensate is released by hand, which suits stations visited during routine rounds; automatic and differential-pressure drains are available if you cannot rely on that. The W code selects the 5 um element instead of the 40 um standard, giving finer particulate removal ahead of the regulator and lubricator. The bowls on this 400 size are polycarbonate, and the unit is rated to 1.0 MPa (145 psi) inlet and -5 to 70 C, non-freezing.
