The AirTAC GC40015MLC2 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 PT1/2" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC40015MLC2 is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, a separate pressure regulator and a separate lubricator assembled as one air-preparation set. This configuration is sized 400 with a PT1/2 (1/2 in) port and PT thread, the standard thread for this series (G and NPT are order options). The filter element is the standard 40 um grade for water and particulate removal, and the bowl is manual-drain, so condensate is emptied by hand during routine checks. The regulator is the low-pressure type, and a round gauge with a psi scale is fitted so downstream pressure can be read directly. Bowls on this size are polycarbonate (PC). 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 is available in sizes 200, 300, 400 and 600, with choices of port size, thread (PT, G or NPT), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge style and scale, and reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 workshop pneumatic press or clamping fixture: the filter removes water and chips from the shop-air line, the low-pressure regulator sets the working pressure read on the psi gauge, and the lubricator mists oil to the cylinder seals.
Conditioning air for packaging and case-erector cylinders on a conveyor line: clean, regulated, lubricated air at the point of use, with the manual-drain bowls emptied during scheduled line checks.
A wall-mounted supply point for impact wrenches, grinders and other air tools in a maintenance bay: one set filters the line, holds the set pressure on the psi gauge and delivers oil mist to keep tools running.
Start with the port step: this unit is size 400 with a PT1/2 port; step up to size 600 for larger ports and flow, or down to 300/200 for smaller lines. Because rated flow is published only as curves, ask us to check the curve against your air demand before ordering. Drain type is a real choice: this unit is manual-drain (code M), which suits attended installations; automatic and differential-pressure drains are available in the family. Filter grade is 40 um standard here; specify code W for 5 um where finer filtration is needed. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are alternatives. PT is the standard thread; G (BSPP) and NPT are order options. A mounting bracket is included with this configuration.
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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for this series as performance curves rather than a single rated figure, so we do not quote a flow number, Cv or SCFM. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet curves on request.
The M in the code means the filter bowl is drained by hand: open the drain to release collected condensate as part of routine checks. If you prefer unattended operation, the GC family also offers automatic and differential-pressure drain options - ask us for those model codes.
