The AirTAC GC400C10ALF2K AirTAC F.R.L. Combo, PT3/8, psi Gauge 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C10ALF2K is an 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. This configuration carries 3/8 inch PT ports, an automatic drain on the filter bowl, the standard 40 um filtration grade, a low-pressure type regulator, an embedded square gauge reading in psi, and a reverse/check valve. The automatic drain ejects collected condensate without anyone opening the bowl by hand, which suits the set for lines that run unattended. The lubricator mists oil into the downstream air to keep air tools and cylinders working as they should.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port options, drain choices (differential-pressure, automatic or manual), a 5 um filter grade (code W), gauge scale choices and G or NPT threads available to order. 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. 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-C1 filter, GR400-C1 regulator and GL400-C1 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.

A machine shop running pneumatic clamps, chucks and tool-change actuators off a 3/8 inch drop gets filtered, regulated and lubricated air from one GC400 set, with the automatic drain keeping condensate off the spindle-area cylinders.
A carton-sealing and case-packing conveyor line with air cylinders working shift after shift uses the GC400 to remove water and grit, hold a steady low-pressure setting, and mist oil into the supply to extend cylinder seal life.
Workbench air drops feeding impact drivers and air ratchets in an assembly plant draw from the GC400: the 40 um filter protects the tools, the low-pressure regulator sets the circuit, and the lubricator keeps the motors oiled.
Step up through the GC sizes (200, 300, 400, 600) to match the port and the flow your line needs; this 400 set sits at PT3/8. Choose the drain to suit the installation: automatic (this unit) for unattended duty, manual where you prefer a hands-on check, or the differential-pressure default. The filter grade is 40 um standard; specify code W for 5 um where finer particulate removal matters. The regulator here is the low-pressure type - confirm the exact adjustment range with us for your circuit. Gauge scale can be MPa, psi or bar; this unit is square, psi. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we cannot quote a number here. Send us your application details and we will confirm the sizing against the datasheet 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and datasheet figures for this 400-size, PT3/8 set on request before you order.
The A in the code selects the automatic drain: the filter bowl ejects collected condensate on its own, with no manual blowing down, which suits unattended lines. The L selects the low-pressure type regulator, intended for circuits that run below standard line pressures; its exact adjustment range is not published on the sheet we work from, so confirm it with us for your application.
