The AirTAC GC40010MLF2W AirTAC F.R.L. Combination, PT3/8, Low-Pressure 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 GC40010MLF2W is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 400-size set on a PT3/8 (3/8 in) port. This configuration is the low-pressure type for circuits that run below standard line pressure, with a manual drain on the filter bowl that you open by hand to expel collected water, a fine 5 um filter element (the W grade, versus the 40 um standard) for cleaner downstream air, an embedded square gauge reading in psi, and no reverse/check valve fitted. The medium is compressed air only, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GC range, which spans 200, 300, 400 and 600 sizes with a choice of ports, thread types, drain styles, filter grades and gauge scales. The 400 size is the mid-large step of the range. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow 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. 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 clamping station running at reduced line pressure, this low-pressure GC set conditions the air in one assembly: the 5 um filter keeps water and fines out of the press cylinder valves, the regulator holds the reduced setting, and the lubricator mists oil to the actuator seals.
For a cartoning or wrapping machine's pneumatic section, the three-unit set at PT3/8 supplies filtered, regulated, lubricated air to the sealing and transfer cylinders, with the manual-drain PC bowl emptied during scheduled changeovers and the psi gauge giving operators a local pressure readout.
On a sortation conveyor where pneumatic diverters and gate cylinders cycle through a shift, this GC400 combination mounted at the drop point delivers cleaned, pressure-set, lubricated air, with the 5 um grade protecting the small control valves that position each gate.
Choose the 400 size with its PT3/8 port when your line sits above the 300 step's porting; the size step is what moves you up the published flow curves, so match it against your air demand. This unit is the low-pressure type, intended for circuits running below standard pressure - ask us to confirm the exact regulation range from the datasheet, as it is not published in the standard table. The manual drain (code M) means an operator opens the bowl drain by hand at intervals; choose automatic or differential-pressure drain codes if you want unattended water removal instead. The 5 um element (W) suits air that feeds precision valves and cylinders; the 40 um standard grade is enough for general plant air. The square gauge reads psi; MPa and bar scales and an external round gauge are order options. Thread is PT as standard, with G (BSPP) and NPT available to order. 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 this series as curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
The L in the code makes this the low-pressure regulator type, intended for circuits running below standard line pressure; the exact regulation range is not published in the standard table, so we confirm it from the datasheet on request. The M makes the drain manual: an operator opens the filter bowl drain by hand to remove collected water, rather than relying on an automatic or differential-pressure drain.
