The AirTAC GC300C15F2K 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 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 oil-mist lubricator built together as one conditioned-air supply unit. This GC300C15F2K is configured for a 1/2 in PT port and carries the standard 40 um filter element with a differential-pressure drain on the filter bowl, a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), an embedded square gauge reading in psi, and a reverse/check valve (code K) that holds the downstream setting if the upstream supply drops. The mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and on this 300 size the filter and lubricator bowls are polycarbonate.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and the option list includes automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 impact wrenches, pneumatic cylinders and clamping fixtures at assembly stations, with the check valve holding the set pressure if the main supply dips.
Conditioning the supply to carton sealers, case erectors and conveyor diverters, where the 40 um element protects valves from water and particulate and the lubricator mists the actuator air.
Supplying tool changers, clamps and air-powered workholding on machining centers, with the regulator holding a steady setting and the square psi gauge giving operators a direct readout at the machine.
Size and port: the 300 size with a 1/2 in PT port sits mid-range in the GC line (200, 300, 400, 600); step up or down in size as your air demand changes, and match the thread to your piping - PT is the standard, with G (BSPP) and NPT available as order options. Drain: the differential-pressure drain on the filter bowl is the default here; automatic (A) or manual (M) drains can be specified instead where the application calls for them. Filter grade: 40 um is standard on this unit; choose the W option for 5 um filtration. Gauge: the embedded square gauge reads in psi, with MPa and bar scales and an external round gauge as alternatives. Flow is published as curves, not a single rating, so send us your flow requirement 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 there is no one l/min or SCFM number we can honestly quote. Tell us your required flow and working pressure and we will confirm the sizing against the datasheet for this 300 size before you order.
The differential-pressure drain is the default on the filter bowl: it bleeds accumulated water automatically when the pressure differential across the element rises. If your application prefers it, the same unit can be ordered with an automatic drain (code A) or a manual drain (code M) instead.
