The AirTAC GC40010MLF2GK AirTAC F.R.L. Combination Unit, G3/8 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC400 is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate, a regulator holds downstream pressure, and a lubricator adds oil mist for downstream air tools and cylinders. This GC40010MLF2GK is built for 3/8 in (G3/8) lines, with a 40 um standard filter element, a manual drain on the filter bowl, a low-pressure type regulator, and an embedded square gauge reading in psi. A reverse/check valve is fitted to hold upstream conditions, and the unit is supplied with a mounting bracket.
This is a genuine AirTAC part. The GC series 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 available as order options, a choice of differential-pressure, automatic or manual bowl drains, a 5 um (code W) filter element option, and square or external round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

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.

On a stamping or assembly press fed at moderate line pressure, the GC40010MLF2GK filters supply air, holds a stable low regulated pressure to the clamping cylinders, and mists oil to keep seals and bores lubricated through long production runs.
Packaging lines run many small actuators and vacuum generators off one drop. This three-unit set cleans the supply, sets a gentle regulated pressure for delicate product handling, and lubricates the cylinders, with the psi gauge giving operators a local reading.
At a workbench or robotic assembly cell, the 40 um filter strips water and pipe scale before air tools, the low-pressure regulator protects sensitive components, and the lubricator feeds air motors and impact drivers, with the check valve holding settings if supply dips.
Start with size and port: the 400 size with its 3/8 in G3/8 port suits mid-range supply lines, and larger sizes carry more flow - size up one step if your line is near the top of its range. Choose the drain to match access: manual (as fitted here) needs periodic bleeding and suits attended installations, while automatic or differential-pressure drains suit unattended duty. The 40 um element is the standard grade; specify the 5 um W option only where finer particulate removal is required. Gauge scale is selectable (MPa, psi or bar) and this unit carries the square psi gauge; PT is the standard thread with G and NPT as order options.
Because flow is published as curves rather than a single rated figure, send us your line conditions and we will confirm sizing against the datasheet before you order. The exact regulation range of the low-pressure type is not published in the standard tables; we will confirm it on request.
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 GC400 as performance curves rather than a single rated figure, so we do not quote a number. Send us your line pressure and downstream demand and we will confirm the datasheet curve and check the sizing for your application before you order.
The manual drain means an operator periodically opens the filter bowl to bleed off collected water - simple and reliable where the unit is checked routinely; automatic or differential-pressure drains are available if you prefer unattended operation. This unit is the low-pressure regulator type; its exact adjustment range is not published in the standard tables, so we will confirm it from the datasheet on request.
