The AirTAC GC300C15AF2W AirTAC F.R.L. Combination, PT1/2, 5 um 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 GC300C15AF2W is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack. This configuration is the 300 size with a 1/2 in PT port, an automatic drain on the filter bowl, a fine 5 um filter element, the standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi), and an embedded square gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter bowl on this 300 size is polycarbonate (PC).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual draining, 40 um standard or 5 um (W) filtration, and gauge scales in MPa, psi or bar. Flow figures are published as curves rather than a single rating, so ask us and we will 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. 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.

Cleaned, regulated and lubricated air feeding clamps, tool-change cylinders and spindle-air seals on a machining centre, with the 5 um element protecting tight-tolerance valves from particulate carryover.
Point-of-use treatment at spray-gun drops in a paint shop, where the fine 5 um grade and oil-mist lubrication support consistent atomising and smooth gun trigger and actuator operation.
Conditioned air for the pneumatic diverters, stop gates and pusher cylinders along a parcel sortation conveyor, with the regulator holding a steady setpoint as gates fire across the shift.
Start with the port and size step: the GC range runs through sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and the 300 size with a 1/2 in PT port suits lines whose air demand sits mid-range. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. Then set the decodable options: drain type (automatic here, with differential-pressure and manual also available), filter grade (this unit carries the fine 5 um W element instead of the 40 um standard), gauge scale (this one reads psi; MPa and bar are alternatives), regulator type (standard; a low-pressure type exists in the range), and thread (PT is the standard; G and NPT are order options). A mounting bracket is included with this unit.
If you need filter, regulator and lubricator as three separate bodies, GC is the right family; if a two-piece filter-regulator plus lubricator suits the installation better, look at the GFC line instead.
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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure, set pressure and air demand, and we will confirm the datasheet flow figures for this 300-size, 1/2 in PT unit on request before you order.
The GC is a separate filter, regulator and lubricator, so each body can be serviced or replaced on its own and the stack can be arranged to suit the installation. The GFC combines the filter and regulator in one body with a separate lubricator. This GC300C15AF2W adds an automatic drain, a 5 um element and a square psi gauge to the three-piece arrangement.
