The AirTAC GC300C15AF2 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C15AF2 is a three-piece AirTAC G-series F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one supply package for a compressed-air line. This size GC300 unit is threaded PT1/2 (1/2 in), carries a 40 um filter element with an automatic drain, and regulates downstream pressure across 0.15-0.9 MPa (20-130 psi) with the standard regulator. An embedded square gauge graduated in psi is fitted, the maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature is -5 to 70 C, non-freezing. The filter and lubricator bowls on this 300 size are polycarbonate (PC); size 600 units in the range use aluminium alloy bowls.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with ports stepping from 1/8 in to 1 in, and options across the range include manual or differential-pressure drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, G (BSPP) or NPT thread variants, and a mounting bracket - included on this unit. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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-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 filtered, regulated and lubricated air to pneumatic clamps, tool-change cylinders and spindle air seals on a machining centre, with the square gauge giving operators a local psi reading at the cell.
Conditioning the air at paint-line drops so water and particulate down to 40 um are removed, pressure is held steady for spray guns, and an oil mist reaches the cylinders on booth doors and reciprocators.
Supplying case packers, carton sealers and bagging machines where cylinders and air grippers run continuously; the automatic drain handles condensate without a daily walk-round, and the lubricator delivers oil mist to the actuators.
Choose the size and port by the flow your line needs: GC sizes 200, 300, 400 and 600 step up through ports 1/8 in to 1 in, and this unit sits at the 300 size with a PT1/2 port. The decodable choices on this family are the filter drain type (automatic, as fitted here, or manual or differential-pressure), the filter grade (40 um standard, 5 um with code W), the gauge scale (MPa, psi or bar - this unit reads psi), the thread (PT standard, with G/BSPP and NPT as order options) and the mounting bracket. Regulation range on this automatic-drain configuration is 0.15-0.9 MPa (20-130 psi); a manual-drain variant widens the lower end to 0.05 MPa (7 psi). AirTAC publishes flow as curves, not a single rating, so send us your flow and pressure requirements and we will confirm 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number here. Tell us your working pressure and required flow and we will confirm the figures from the datasheet for the GC300 at PT1/2 before you order.
The GC combines three separate units - filter, regulator and lubricator - so each element can be serviced or replaced on its own; this version has an automatic-drain filter with a 40 um element. The GFC pairs a filter-regulator body with a lubricator in two units. Both filter, regulate and lubricate; the GC layout gives you three discrete bowls and adjustments. Ask us to confirm the datasheet for either before ordering.
