The AirTAC GC40010AC2 AirTAC F.R.L. Combination, PT3/8, Auto Drain 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 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010AC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, so the compressed air supply is cleaned of water and particulate, held at a set working pressure, and given oil-mist lubrication in a single installation. This 400-size unit is ported PT3/8 (3/8 in, PT thread standard; G and NPT are order options), carries a 40 um filter element, and has an automatic drain that expels collected condensate without manual attention. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round gauge on a psi scale is fitted so the set pressure can be read directly. The filter and regulator bowls are PC (polycarbonate) at this size.
This is a genuine AirTAC part. The GC family spans 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um (W) filter grade, gauge scale choices, and G or NPT thread options. Maximum 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 we confirm sizing and datasheet figures 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 0.15 - 0.9 MPa (20 - 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.

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 the actuated clamps, tool-changer cylinders and chip-clearing jets on a CNC machining centre, with the automatic drain keeping condensate out of the supply between shifts.
Supplies the pneumatic cylinders on a carton-forming and case-sealing conveyor line, where the 40 um filter protects valve spools and the lubricator keeps cylinder seals running smoothly through long production runs.
Installed as the air-preparation drop at a manual assembly bench, giving operators a psi gauge to set working pressure for air tools and small press cylinders, with oil misting for tool longevity.
Start with the port and size step: this unit is 400 size at PT3/8, and moving up or down a size changes both the port and the flow capacity, so match the step to the air demand of the machine it feeds. The drain is automatic on this configuration, which suits unattended or hard-to-reach installations; differential-pressure and manual drains are available on other codes. The 40 um element is the standard grade; specify the W option (5 um) where finer filtration is needed. The fitted gauge reads in psi; MPa and bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included.
Because AirTAC publishes flow as curves and not as a single rated number, we do not quote a rated flow here. Ask us to confirm the datasheet curve against your application's air consumption before ordering, and we will verify the sizing.
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 state a rated flow number here. Ask us to confirm the datasheet flow curve for the 400 size at 3/8 in against your application's air consumption, and we will send the figures so you can size the unit correctly.
The A in the code GC40010AC2 means the filter bowl drains automatically, expelling condensate without anyone opening the drain, which suits installations that run unattended or sit where a manual drain is awkward. The GC family also offers a differential-pressure drain (the default) and a manual drain on other codes if you prefer those.
