The AirTAC GC300C15AF2G AirTAC F.R.L. Unit, G1/2, 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 GC300C15AF2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator piped as one complete air-preparation set. This configuration is built around a 1/2 in (G1/2) port with G (BSPP) thread, a 40 um filter element, an automatic drain on the filter bowl, and a standard regulator whose setting range is 0.15-0.9 MPa (20-130 psi). The square pressure gauge is fitted with a psi scale, the polycarbonate bowl suits the size-300 body, and a mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating 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 options from 1/8 in to 1 in, G or NPT thread alternatives, manual or differential-pressure drain choices, a 5 um filter grade option, and gauge scale choices of MPa, psi or bar. 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. 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-C1 filter, GR300-C1 regulator and GL300-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 impact wrenches, air ratchets and clamping cylinders at a final-assembly station, where one set cleans the water and particulate out of the shop air, holds a steady regulated pressure, and carries oil mist to the tools.
Preparing air for the cylinders and grippers that index, press and seal cartons on a packaging conveyor, keeping moisture and scale out of the actuators while the lubricator protects seals and moving surfaces through continuous shifts.
Conditioning the supply to pneumatic clamps, tool-change actuators and chip-clearing jets on a machining centre, so the machine sees dry, filtered air at a stable set pressure with lubrication for the air-driven components.
Start with the port step: this unit carries a 1/2 in G1/2 connection in the size-300 body; if your line needs more or less flow capacity, step up or down through sizes 200, 300, 400 and 600, which move port size and flow capacity together. Choose the drain to match maintenance access: automatic (as fitted here) empties the bowl without operator attention, manual needs a routine drain action, and differential-pressure draining is the catalog default. The 40 um element fitted here is the standard grade; specify code W for the 5 um grade where finer particulate removal matters. Gauge scale is selectable (MPa, psi or bar) and this unit carries the square gauge with a psi scale. Thread is PT as the standard, with G (BSPP) and NPT available as order options; a mounting bracket is included on this configuration. Because flow is published as curves rather than a single rating, ask us to confirm sizing 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for this series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing against the datasheet curves on request before you order.
The A in the model code specifies an automatic drain, which expels collected condensate from the filter bowl without an operator having to open it - useful on lines that run unattended. The catalogue also offers manual draining and the differential-pressure default, so you can order a GC300 with a different drain code if your maintenance routine suits it better.
