The AirTAC GC400-10 AirTAC F.R.L. Combination, PT3/8, 5 um Filter 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400-10 is a genuine AirTAC three-piece F.R.L. combination: separate filter, regulator and lubricator units assembled as one air-preparation set. This configuration is built for 3/8 in PT ports, carries the 5 um filter element (the finer of the two published grades), an automatic drain on the polycarbonate filter bowl, and a round pressure gauge reading in psi. A reverse/check valve is fitted and the set includes a mounting bracket. In use it prepares compressed air in three steps: it strips water and particulate down to 5 um, holds downstream pressure steady anywhere in the 0.15-0.9 MPa (20-130 psi) adjustment range, and meters a fine oil mist to lubricate downstream cylinders, valves and air tools.
This is a genuine AirTAC part in the GC series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure draining, 40 um or 5 um filtration, and gauge scales in MPa, psi or bar. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Rated flow is published as curves rather than a single figure, so ask us to confirm flow and datasheet details 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. 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.

Spray guns and air-assisted applicators need air that is dry, filtered, held at a set pressure and lightly oiled. This combination conditions the drop line feeding a paint booth: the 5 um element removes fine particulate before it can blemish a finish, the regulator holds gun pressure steady, and the lubricator keeps gun triggers and spindles working smoothly.
Pneumatic clamps, tool-change cylinders and chip-clearing blasts on a machining centre all draw from one prep point. This F.R.L. set at the cell inlet cleans the shop air to 5 um, locks clamp pressure against shop-line fluctuation, and oils the actuators, while the automatic drain handles condensate without an operator stopping by.
High-cycle pick-and-place cylinders, grippers and diverters on a packaging line wear fast on unconditioned air. Feeding the machine's valve stack through this combination gives filtered, moisture-managed air at a stable set pressure with continuous oil-mist lubrication, and the check valve holds the circuit if the supply side dips.
Size and port: the 400 size with 3/8 in PT ports sits mid-range in the GC series; step up or down (200/300/400/600, 1/8 in to 1 in) according to the air demand of the circuit - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. Drain: this unit has the automatic drain, which bleeds collected condensate without manual attention; manual and differential-pressure drain versions exist in the family. Filter grade: the 5 um element (code W) is fitted here instead of the standard 40 um, the right choice where finer particulate removal matters. Gauge: this build carries the external round gauge with a psi scale; embedded square gauges and MPa or bar scales are the other catalogue options. Thread: PT is the standard; G (BSPP) and NPT are order options. A mounting bracket is included and a reverse/check valve is fitted.
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 number, so we do not quote a fixed l/min or SCFM figure. Tell us your application and we will confirm the flow and full datasheet details for this model on request before you order.
The W in the code GC40010AC2WK selects the 5 um element instead of the 40 um standard, and the A selects the automatic drain, which ejects collected condensate on its own instead of waiting for a manual or differential-pressure drain cycle. Both are catalogue options on the GC filter stage, so you can order the family with 40 um filtration or a different drain if that suits the installation better.
