The AirTAC GC40010MLF2WGK AirTAC F.R.L. Combination, G3/8 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 GC40010MLF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 400 configuration is fitted with G3/8 ports, a 5 um filter element (the finer of the two published grades), a manual drain on the filter bowl, a low-pressure type regulator, an embedded square gauge with psi scale, a reverse/check valve, and a mounting bracket. The filter removes water and particulate, the regulator holds your set downstream pressure, and the lubricator adds oil mist for downstream air tools and cylinders.
This is a genuine AirTAC part. The GC line is published in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades, gauge scales and thread options (PT standard; G and NPT order options). Flow is published as curves rather than a single rated figure, so ask us to confirm 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. 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.

|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding filtered, regulated and lubricated air to a machining centre's pneumatic tool clamps and chip-clearing cylinders, with the 5 um element protecting fine control valves from particulate and the psi gauge giving operators a local pressure readout.
Conditioning the air feeding conveyor stoppers, diverters and case-sealing cylinders on a packaging line, where the lubricator keeps cylinder seals moving smoothly through long shifts and the check valve holds the circuit if supply pressure dips.
Installed at a plant-air drop point serving assembly stations, cleaning the compressed air of water and debris, regulating it to a stable low set pressure for delicate fastening tools, and metering oil mist to keep air drivers lubricated.
Start with size and port: the 400 size with G3/8 suits lines running 3/8 inch piping, and the larger the size the greater the port and flow capacity - match the size step to your required flow. Choose the filter grade: 40 um is standard for general protection, 5 um (this unit, code W) for finer downstream cleanliness. Drain type matters: manual drain (this unit) needs periodic draining by hand, while automatic and differential-pressure drains discharge condensate without operator attention. For the regulator, this is the low-pressure type - its exact adjustment range is not published, so confirm it with us. Gauge scale is selectable (MPa, psi or bar); this unit carries a square psi gauge. Thread is PT as standard with G and NPT as order options, and a bracket is included here.
One honest note on sizing: AirTAC publishes flow only as curves, not a single rated number. Send us your application flow and pressure and we will confirm the right size from the datasheet 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 this series only as curves, not as a single rated figure, so we do not quote a number. Tell us your required flow and working pressure and we will confirm from the datasheet whether the 400 size at G3/8 suits your application before you order.
This unit's filter bowl has a manual drain (code M): an operator opens it periodically to discharge collected condensate. The automatic drain option discharges condensate on its own, and the differential-pressure drain is the default. Choose manual where someone is on site regularly; choose automatic for less accessible installations.
