The AirTAC GC400C15MLF2GK AirTAC F.R.L. Combination, G1/2 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 GC400C15MLF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator assembled together as one set, in the 400 size with G1/2 (BSPP) ports. This configuration carries a manual-drain metal filter bowl, the standard 40 um filter element, a low-pressure regulator fitted with an embedded square gauge scaled in psi, and a reverse (check) valve; a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with automatic or differential-pressure draining, a 5 um filter element (code W), MPa/psi/bar gauge scales, and G or NPT threads alongside the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Feeds filtered, regulated and lubricated air to the pick-and-place cylinders and grippers on a packaging machine, with the low-pressure regulator holding a gentle setting for light actuation work.
Supplies the air jets and pneumatic threading aids on spinning and weaving machines, where the lubricator keeps downstream air motors and cylinders running smoothly through long shifts.
Serves as the F.R.L. at a CNC machining cell, conditioning the air that feeds workholding clamps, air chucks and pneumatic press cylinders before it reaches the actuation circuits.
The main decodable choices are the size and port step, matched to the air demand of your line - the 400 size with G1/2 ports sits mid-range in the GC family. Drain type matters: this unit has a manual drain, which you empty by hand, while automatic and differential-pressure drains are available in the same family. The filter element here is the standard 40 um grade; a 5 um element (code W) can be ordered where finer filtration is needed. The embedded square gauge on this code reads in psi, and MPa or bar scales can be specified instead. Thread is G (BSPP) on this code; PT is the AirTAC standard and NPT is an order option. Note that the regulator is the low-pressure type and its exact adjustment range is not published, so confirm it with us. Because flow is published as curves rather than a single rating, ask us to check the curve data 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-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. Tell us your working pressure and air demand and we will confirm the flow from the datasheet curves before you order.
The M in the code specifies a manual drain, so the filter bowl is emptied by hand as part of routine maintenance. The same GC family can be ordered with an automatic drain or with the default differential-pressure drain if you would rather not drain the bowl manually.
