The AirTAC GC400-10A AirTAC Low-Pressure F.R.L. Combination, 3/8 in PT 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 AirTAC GC400-10ALC2K is a three-piece F.R.L. combination unit: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package for a 3/8 in PT port. This configuration is the low-pressure regulator type with an automatic drain on the filter bowl, a 40 um standard filter element, a round external gauge scaled in psi, and a reverse/check valve fitted. In use, the filter removes water and particulate from the compressed air, the regulator holds a stable low working pressure downstream, and the lubricator meters oil mist into the air line to keep downstream pneumatic tools and actuators running.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um (W) filter grades, gauge styles and MPa/psi/bar scales, and PT, G or NPT threads. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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. 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 low-pressure clamping or forming station, this unit filters the shop air, holds the regulator at the fixture's working pressure, and carries oil mist to keep the clamp cylinders sealing and moving smoothly cycle after cycle.
Feeding a cartoning or wrapping machine's valve island, the combination conditions the whole supply in one assembly: water and particulate out, stable low pressure in, and a light oil mist for the machine's air cylinders.
On a sorting or palletising line where diverters and stop gates run on air cylinders, the GC400 supplies cleaned, regulated, lubricated air at the line so gate action stays consistent through the shift.
Start with the size and port: this is the 400 size with a 3/8 in PT port, one step up from the 300 size, so step up or down within the GC range if your line flow calls for a different port. The automatic drain on this unit (code A) bleeds condensate from the filter bowl without manual attention - choose manual or differential-pressure drain instead if your installation prefers it. The filter grade here is the 40 um standard element; specify the W option for 5 um finer filtration. The gauge on this code is the external round type scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available as order options, and the mounting bracket is included. Note this is the low-pressure regulator type (code L): its exact adjustment range is not published in the material we hold, so ask us to confirm it against your working pressure before ordering. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing before you order.
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, not as a single rated number, so we do not quote a l/min, m3/h or SCFM figure. Send us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request before you order.
Code L makes this the low-pressure regulator version of the GC400, intended for lower working pressures than the standard type; its exact adjustment range is not published in our material, so we confirm it on request. Code A is the automatic drain: the filter bowl bleeds condensate off by itself instead of needing a manual drain, and the round gauge fitted on this code reads in psi.
