The AirTAC GC40010LF2WGK AirTAC F.R.L. Combination, G3/8, 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 PT3/8" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010LF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set for compressed air. This 400-size unit is built for G3/8 (3/8 in) ports with G (BSPP) thread. The filter element is the fine 5 um grade (the W option; 40 um is the standard element) with a differential-pressure drain on the bowl, which on this 400 size is polycarbonate. The regulator is the low-pressure type (code L) and carries an embedded square gauge reading in psi; an external round gauge is available as an option. A reverse/check valve (code K) is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family spans 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, drain choices of differential-pressure, automatic or manual, and 40 um or 5 um filtration. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |

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.

Feeds spray guns and air-assisted applicators on a paint line, where the 5 um element, stable low-pressure setting and oil misting protect finish quality at the booth.
Prepares the air supply for cylinder- and valve-driven case packers, tapers and labellers running on a 3/8 in ring main, with the check valve holding the set pressure upstream of sensitive actuators.
Serves the clamping, tool-change and chip-clearing circuits of CNC machines and pneumatic presses, giving each cell one point where air is filtered, regulated and lubricated.
Step up through the GC sizes (200/300/400/600) as your port and air demand grow; this 400 unit takes a G3/8 connection. Choose the drain to match maintenance access: differential-pressure (as fitted here), automatic, or manual. Pick the filter grade for the downstream equipment: 40 um is the standard element, 5 um (this unit, code W) suits finer-pneumatic work. Gauge scale is selectable (MPa, psi or bar) and this unit ships with the embedded square gauge in psi. Thread is PT as standard with G and NPT as order options - this code specifies G. Bracket is included.
One honest note on sizing: filter and regulator flow are published as curves, not a single rated number, and the exact adjustment range of the low-pressure regulator type is not published. Send us your line pressure, set pressure and air demand and we will confirm this unit against 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 family as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet on request.
The W in the code GC40010LF2WGK selects the optional 5 um element instead of the standard 40 um, and the 2 selects the psi gauge scale (MPa and bar are also available). The L selects the low-pressure regulator type, whose exact adjustment range is not published - we will confirm it against the datasheet for your set pressure.
