The AirTAC GC300C08ALC2K AirTAC F.R.L. Combination PT1/4 Auto Drain 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator built up as one working unit. This GC300C08ALC2K is made for a PT1/4 (1/4 in) port and carries an automatic drain on the filter bowl, a 40 um standard filter element, a low-pressure regulator, a round external pressure gauge reading in psi, a reverse/check valve and a mounting bracket. The bowl is metal. 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 family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with catalogue choices of drain type, 5 um or 40 um filtration, gauge style and scale, G or NPT thread options and bracket or no-bracket mounting. Flow for this family is published as curves rather than a single rating, so ask us to confirm the sizing figures from the datasheet for your application.

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: GF300-C0 filter, GR300-C0 regulator and GL300-C0 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 spray booths and paint guns on an automotive finishing line, where the filter strips water and particulate, the low-pressure regulator holds a steady setting, and the lubricator mists oil to the air tools downstream.
Point-of-use conditioning at CNC machining cells: clean, regulated and lubricated air for pallet clamps, air chucks and hand tools, with the check valve holding the circuit against backflow.
Conditioning the air feeding cylinders and diverters on a carton packaging conveyor, where the automatic drain handles condensate through continuous production shifts without operator attention.
Step through sizes 200/300/400/600 to match the port and the flow your line needs - the 300 size here takes a 1/4 in PT port. On this unit the drain is automatic, so condensate is ejected without manual attention; manual and differential-pressure drains are the other catalogue choices. Filtration is the 40 um standard element (5 um is the W option), the regulator is the low-pressure type, and the gauge is a round external gauge on the psi scale - MPa and bar scales and an embedded square gauge are the alternative options. Thread is PT as standard; G (BSPP) and NPT are orderable specification options, and the mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the sizing against the datasheet before you order.
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-C0 regulator with a GF300-C0 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 flow number here. Tell us your application and required port size, and we will confirm the sizing from the datasheet on request before you order.
This unit is built with the low-pressure (L) regulator type, and the exact setting range for that version is not published in our data, so we confirm it from the AirTAC datasheet on request. What the code does fix is the rest of the build: PT1/4 port, automatic drain, 40 um element, round psi gauge, reverse/check valve and included bracket.
