The AirTAC GC30015MLC2K AirTAC F.R.L. Combination Unit PT1/2 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 PT1/2" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC30015MLC2K is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate, a regulator sets downstream pressure, and a lubricator adds oil mist for downstream air tools and cylinders. This 300-size unit is configured for a PT1/2 (1/2 in) port with standard PT thread, a manual drain on the filter bowl, the standard 40 um filter element, and a low-pressure type regulator. It is supplied with a round external gauge reading in psi, a reverse/check valve fitted, and a mounting bracket.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT as order options), drain types, filter grades and gauge scales. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures 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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

Feeds cleaned, regulated and lubricated air to shop-floor pneumatic presses and clamping fixtures, with the check valve helping hold the downstream circuit against backflow.
Supplies conditioned air to packaging machinery actuators and sealing cylinders, where the lubricator keeps air cylinders running smoothly through long production shifts.
Serves as the point-of-use F.R.L. at a 1/2 in assembly-station air drop, filtering line water and particulate and letting each operator set and read local pressure in psi.
Start with the port step: the 300 size carries a 1/2 in port, and the larger the size (200/300/400/600), the larger the port and the greater the flow capacity - match the size to the air demand of the circuit rather than upsizing blindly. Choose the drain type for the filter bowl: manual drain (this unit) requires periodic draining by an operator, while automatic and differential-pressure drains discharge condensate without intervention. The standard 40 um element suits general-purpose air preparation; a 5 um element (code W) is available where finer filtration is needed. Gauge scale (MPa, psi or bar) and round vs square gauge are selectable, as are PT, G or NPT threads and the bracket.
Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. The regulator in this unit is the low-pressure type; we confirm its adjustment range from the datasheet on request.
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 GR300-15 regulator with a GF300-15 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 number. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
The M in the code GC30015MLC2K specifies a manual drain on the filter bowl, so condensate is drained by an operator rather than automatically. The L code specifies the low-pressure type regulator; its exact adjustment range is not published in the standard table, so we confirm it from the datasheet on request. The unit also carries a round psi gauge and a fitted reverse/check valve (code K).
