The AirTAC GC40010MF2GK AirTAC F.R.L. Combination, 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 GC40010MF2GK is an AirTAC GC400 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator that together clean, regulate and lubricate compressed air on one 3/8 in (G3/8) supply line. This configuration carries a manual-drain filter bowl in polycarbonate with the standard 40 um filtration element, an embedded square gauge reading in psi, a fitted reverse/check valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options that include automatic or differential-pressure drains, a 5 um filter element (code W), round external gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures against 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 0.05 - 0.9 MPa (7 - 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: GF400-10 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.

Feeds clean, regulated and lubricated air to the clamping fixtures, tool-changer cylinders and pneumatic actuators of a CNC machining centre on a 3/8 in drop from the shop main, with the psi gauge letting setters verify set pressure at a glance.
Prepares air for the diverters, pushers and sealing cylinders on a carton packaging conveyor, where the manual-drain bowl is bled at shift start and the check valve holds downstream pressure if the supply dips.
Conditions the air feeding loom jets and fabric-handling cylinders in a weaving shed, with the lubricator delivering an oil mist to keep cylinder seals and valves running smoothly through long production runs.
Size up a GC combination by the port and flow step: 200 through 600 map to ports from 1/8 to 1 in, so match the size to the air demand of the downstream circuit - the 400 size with its 3/8 in port suits mid-range machine supply lines. Choose the drain for the filter bowl: manual drain (this model) needs periodic bleeding by an operator, automatic drain suits unattended installations, and differential-pressure drain is the catalogue default. Filter grade is 40 um standard; specify 5 um (code W) where finer particulate removal is needed. Gauges are embedded square as standard with MPa, psi or bar scales, and an external round gauge is optional. Thread is PT as the catalogue standard with G and NPT as order options - this unit is the G-thread version. Brackets are included on this configuration. Because flow is published as curves and not a single rating, 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 the GC series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and required flow, and we will confirm the datasheet figures for the GC400 size against it before you order.
The M in the code specifies a manual-drain filter bowl, which an operator drains periodically - a good fit for attended lines with a regular maintenance routine. The GC series is also available with automatic drain (code A) or the differential-pressure drain default, so choose those variants for unattended installations.
