The AirTAC GC40010LF2GK AirTAC F.R.L. Combination, G3/8, 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 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010LF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioned-air station for compressed air. This configuration is built on the GC400 size with a G3/8 (3/8 in) port, the standard 40 um filter element and a differential-pressure drain that bleeds collected condensate automatically as the pressure differential across the element rises. The regulator is the low-pressure type, and this code carries a fitted square gauge reading in psi, a reverse/check valve on the regulator and a mounting bracket, so the unit can be hung directly on the machine frame or a preparation panel.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with port sizes stepping up from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um (W) filter element, alternative gauge scales and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Mounted at the drop from a main compressed-air header, the filter removes water and particulate, the low-pressure regulator sets a stable supply pressure and the lubricator carries a fine oil mist to the cell's air tools and cylinders.
Actuated diverters, clamps and pushers on a packaging conveyor run off this combination: 40 um filtration protects the valves, the regulator holds the working pressure the actuators were designed for, and the lubricator keeps the cylinders sealing smoothly.
On a machining or assembly bench, this three-unit station conditions the air feeding jigs, clamps and small air motors, with the included bracket mounting it at the bench regulator position and the psi gauge giving the operator a direct pressure readout.
Start with the size and port: the 400 body with a 3/8 in connection suits lines where conditioning capacity must sit above the 300 step, and the larger 600 size is there if your demand grows. Choose the drain to match access: differential-pressure (this unit) drains itself as the element loads, automatic drains on a cycle, and manual only where someone walks the line. The standard 40 um element covers general plant air; specify the 5 um (W) grade where downstream valves or instruments need finer filtration. This code is the low-pressure regulator type with a square psi gauge and a reverse/check valve fitted; gauge scale (MPa/psi/bar) and thread (PT standard, G or NPT to order) are the other decodable choices, and a bracket is included.
One honest note before you order: AirTAC publishes flow as curves, not a single rated number, so we cannot quote you a rated flow figure here. Send us your application details and we will confirm the datasheet and sizing against your demand before you commit.
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 performance curves rather than a single rated figure, so we do not quote a rated flow number here. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the datasheet and check the sizing against your application on request.
The L in the code GC40010LF2GK marks the low-pressure regulator type, intended for circuits that work below the standard regulator band; the exact adjustment range for this type is not published in the sheet we work from, so we confirm it on request. The drain is the differential-pressure type: collected condensate is expelled automatically as the pressure differential across the 40 um filter element builds, with no daily manual draining required.
