The AirTAC GC300C15F2WK 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 GC300C15F2WK is an AirTAC GC-series three-unit F.R.L. combination: a filter, a regulator and a lubricator supplied as one set, so a single PT1/2 connection delivers filtered, regulated and oil-mist lubricated compressed air to your equipment. This 300-size unit carries the optional 5 um (W-grade) element for finer water and particulate removal, a differential-pressure drain for condensate discharge, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). An embedded square gauge reading in psi is fitted, a reverse/check valve is included, and a mounting bracket comes with the unit. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC range is offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with drain, filter-grade, gauge, thread (PT standard, with G and NPT as order options) and reverse-valve choices to match your installation. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and the full datasheet 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 a CNC machine's pneumatic clamps, tool-change cylinders and chip-door actuators from a single PT1/2 drop, with the 5 um element protecting the machine's valves.
Supplying the case-packing and carton-sealing cylinders on a beverage bottling conveyor, where fine filtration guards the directional valves and the lubricator keeps cylinder seals running smoothly.
Running pneumatic clamp and swing cylinders along an automotive trim line, with the regulator holding consistent clamp pressure and the fitted reverse/check valve on the supply side.
Step through the size range by port and required flow: 200, 300, 400 and 600, with this unit at 300 size on a PT1/2 port. On the filter you choose the drain type - differential-pressure (the default, fitted here), automatic (A) or manual (M) - and the element grade: 40 um standard or 5 um with the W code, which this unit carries. The regulator is the standard type, adjusting 0.15-0.9 MPa (20-130 psi); gauge choice is the embedded square gauge (psi scale on this unit, with MPa or bar scales available) or an optional external round gauge. Thread is PT as standard with G (BSPP) and NPT as catalogue options, a reverse/check valve (K) is fitted on this unit, and a mounting bracket is included. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements and we will confirm the correct size against your application 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. Send us your required flow and working pressure and we will confirm the sizing and the full datasheet figures for this PT1/2 unit on request.
This unit carries the optional W-grade 5 um element, which removes finer particulate than the 40 um standard element and gives closer protection to downstream valves and cylinders. If your line does not need fine filtration, the same GC300 combination is available with the 40 um element - ask us to quote that version.
