The AirTAC GC400-10G AirTAC F.R.L. 3/8in Filter Regulator Lubricator 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 AirTAC GC400-10G is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air in one assembled set: a separate filter, a separate regulator and a separate lubricator. The 400 size is fitted with a G3/8 (BSPP) port. This configuration carries a 5 um filter element (finer than the standard 40 um), a manual drain on the filter bowl, and a fitted round pressure gauge reading in psi. The filter bowl is polycarbonate, and the maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so we confirm the datasheet figures for your application on request.

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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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". |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 filtered, regulated and lubricated air to a machining centre's pneumatic tool-change and clamping circuits, with the 5 um element protecting downstream valves from fine particulate and the psi gauge giving operators a local setpoint readout.
Conditions the air feeding conveyor diverters, case sealers and bagger cylinders on a packaging line, with lubrication carried to the actuators and the manual drain emptied during scheduled line cleaning.
Supplies regulated, oil-mist lubricated air to impact wrenches and nutrunners at a bench assembly cell, where the 3/8 in G-thread port matches the cell's drop-leg piping and the round psi gauge lets assemblers verify tool supply pressure.
Size and port step up with required flow: the 400 size with its G3/8 port sits mid-range in the GC family, above the 200/300 sizes and below the 600. Choose the drain type to suit maintenance routines: manual drain (this unit) is emptied by hand, while automatic and differential-pressure drains discharge condensate without operator action. The 5 um element (code W) suits applications needing finer particulate removal than the standard 40 um. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are alternatives. Thread here is G (BSPP); PT is the standard thread and NPT is also an order option. A mounting bracket is included. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 there is no one rated flow number we can quote. Tell us your inlet pressure and the flow your application needs, and we will confirm the figures from the datasheet on request before you order.
The M in the code selects a manual drain on the filter bowl: condensate is emptied by hand, which suits installations checked as part of a maintenance routine. The W code selects the 5 um filter element instead of the standard 40 um, giving finer particulate removal ahead of the regulator and lubricator.
