The AirTAC GC30015MLC2WK AirTAC F.R.L. Combination, 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 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one supply unit that cleans, regulates and lubricates compressed air in a single installation. This GC300 configuration is built around a PT1/2 (1/2 in) port with standard PT thread, carries a 5 um filter element (the finer of the two catalogue grades), a manual drain on the filter bowl, a low-pressure type regulator, a reverse/check valve and an external round gauge with a psi scale. The polycarbonate bowls suit the 300 size, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and G (BSPP) or NPT thread options to order. Max 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 the datasheet figures 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: 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.

Feeding a machining centre's pneumatic circuits from a 1/2 in drop: the 5 um element removes water and fine particulate before the air reaches tool-clamp and chip-clearing cylinders, the regulator holds the circuit setpoint and the lubricator mists oil to the actuators.
Supplying a bottling or cartoning line's air header, where the low-pressure regulator suits circuits running at modest setpoints, the manual drain is emptied at shift checks, and the lubricator keeps the line's air cylinders running smoothly across long production runs.
A wall-mounted take-off point on the factory air ring main: the bracket-mounted three-unit set conditions the air once for a whole assembly cell, the check valve holds the downstream circuit if the main is shut off, and the psi gauge gives operators a local pressure readout.
Start with the size and port: the GC300 with its PT1/2 port sits in the middle of the 200/300/400/600 range, so step up or down according to the air demand of the circuit it feeds. Choose the drain to match access: manual drain (as fitted here) needs someone to open it, while automatic and differential-pressure types empty the bowl themselves. Pick the filter grade for the downstream equipment: 40 um is the standard element and 5 um (code W, fitted here) protects finer components. Select the regulator type for the circuit pressure - this unit is the low-pressure type - and the gauge style and scale (embedded square as standard, external round optional, in MPa, psi or bar; this unit has a round psi gauge). Thread is PT as standard with G (BSPP) and NPT available to order, and a bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so ask us to confirm the flow and datasheet 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so there is no one number we can quote. Tell us your application and we will confirm the flow and datasheet figures for this 300-size, PT1/2 unit on request.
Both are decodable from the code: M in the drain position specifies a manual drain, which you open by hand to empty the filter bowl - a good fit where the unit is checked daily and automatic draining is not required. W in the grade position specifies the 5 um element, the finer of the two catalogue grades (40 um is standard), for protecting more sensitive downstream equipment.
