The AirTAC GC400C15LF2 AirTAC F.R.L. Combination, PT1/2, 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400C15LF2 is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air from a single assembled set: a separate filter, a separate regulator and a separate oil-mist lubricator. This configuration is built on the GC400 size with a 1/2 in PT port. The filter section carries the standard 40 um element with a differential-pressure drain, the regulator is the low-pressure type with an embedded square gauge scaled in psi, and the lubricator delivers oil mist downstream to protect air tools and cylinders.
This is a genuine AirTAC part from the GC series, which spans the 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, thread options PT (standard), G and NPT, drain choices, filter grades and gauge scales. Rated flow for this combination is published as curves rather than a single figure, so we confirm the datasheet and sizing figures on request before you order.

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.

Feeding a row of impact wrenches, nut runners and air ratchets at a vehicle assembly station: the filter removes water and chips from the plant supply, the low-pressure regulator holds a gentle setting for delicate fastening, and the lubricator keeps the tools oiled through a full shift.
Conditioning the air feeding the pick-and-place and clamp cylinders on a carton packaging conveyor: clean, regulated, lubricated air keeps the pneumatic actuators and valves moving smoothly, with the 1/2 in PT port matching the main drop to the line.
Supplying a woodworking shop's spray guns and air blow-off nozzles: the 40 um filter strips water that would ruin finishes, the regulator holds the low working pressure the gun needs, and the oil mist protects the shop's air tools on the same bench.
Start with the port and flow step: the GC400 size with its 1/2 in PT port sits in the middle-upper range of the GC line, so step up to GC600 or down to GC300 depending on the air demand of the circuit. Drain type is a real choice: this unit uses the differential-pressure drain (the default), while automatic (A) and manual (M) versions exist if you need unattended or operator-controlled draining. Filter grade is 40 um standard; specify 5 um (code W) where finer particulate removal matters. The embedded square gauge here is scaled in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
Because rated flow is published only as curves and not as a single rating, ask us to confirm sizing against your application's air consumption 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 application's air consumption and we will confirm the flow and sizing from the datasheet on request before you order.
The L in the code marks this as the low-pressure regulator type, intended for circuits that work below the standard regulator's range; the exact adjustment range for this variant is not published in our sheet, so we confirm it on request. The filter section uses the differential-pressure drain (the default), which bleeds collected water automatically as flow passes through, with automatic (A) and manual (M) drain versions available in the series.
