The AirTAC GC40015MLF2WGK AirTAC F.R.L. Combination G1/2, 5 um 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 PT1/2" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC40015MLF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one supply package for compressed air. This configuration is built around a G1/2 (BSPP) port on the size 400 body. The filter element is the fine 5 um grade (code W) and the bowl uses a manual drain, so an operator opens the drain valve periodically to remove collected water instead of relying on an automatic or differential-pressure drain. The regulator is the low-pressure type, fitted with an embedded square gauge reading in psi for direct setpoint checks, and a reverse/check valve is fitted to hold downstream conditions if supply pressure is lost. A mounting bracket is included.
This is a genuine AirTAC part. The GC three-unit F.R.L. family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and with or without a reverse/check valve. Flow is published as curves rather than a single rating, 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. 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.

|---|---|
| 15 | Port size PT1/2". 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. |

| 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 filtered, regulated and lubricated air to the tool-change clamps, air bearings and actuated doors of a CNC machining centre, with the 5 um element protecting fine pilot valves from particulate carryover.
Supplies the carton-forming cylinders, sealing heads and divertor gates on a packaging conveyor line, giving operators one point to set line pressure, top up oil mist and drain the bowl during shift checks.
Conditions the air feeding spray guns in a paint or coating booth, where the 5 um grade limits water and particle spotting on the finish and the lubricator mists oil for the gun's air motor.
Start with the port and size step: this unit is size 400 with a G1/2 port; smaller or larger sizes (200/300/400/600) step port and flow capacity up or down, so match the step to the air demand of the machine it feeds. Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering. Next choose the drain: this code carries a manual drain, which suits attended installations; automatic or differential-pressure drains are available on other codes for unattended duty. Filtration here is the 5 um fine grade (code W); the 40 um standard grade is the alternative where only coarse water and particulate removal is needed. The gauge on this unit is the embedded square type with a psi scale; MPa or bar scales and an external round gauge are options. Thread is G (BSPP) on this code; PT is the standard thread and G/NPT are order options. A mounting bracket is included.
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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote a number that is not in the datasheet. Send us your line pressure and air demand and we will confirm the flow figures from the datasheet for this exact unit on request.
The L marks the low-pressure type of regulator, suited to applications where the setpoint sits below the standard range; the exact range for this variant is not published, so confirm it with us on request. The M marks a manual drain on the filter bowl, meaning an operator opens the drain valve periodically to expel collected water - automatic (A) and differential-pressure (blank) drains are available on other codes for unattended duty.
