The AirTAC GC300C10F2GK AirTAC F.R.L. Combination, G3/8 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 GC300C10F2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one treatment stack. This size 300 unit is built for 3/8 in ports with G (BSPP) threads. The filter section carries the standard 40 um element with a differential-pressure drain, the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the lubricator meters oil mist into the downstream air. A square gauge scaled in psi is fitted, a reverse/check valve is included, and a mounting bracket comes with the unit. Maximum working (inlet) pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the filter and lubricator bowls on this size are polycarbonate.
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, drain types (differential-pressure, automatic or manual), a 5 um filter element option (code W), gauge scale choices, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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 clean, regulated and lubricated air to a CNC machine's pneumatic clamps, tool-change cylinders and air blast lines, where the 40 um filter sheds water and chips-laden particulate and the regulator holds a steady setting for repeatable clamping.
Conditioning the air at drop points on a paint shop line: the filter removes water that would fish-eye a finish, the regulator holds the set pressure at the booth, and the lubricator oils the air motors and trigger valves on the line.
Supplying treated air to the cylinders and grippers on a carton-sealing and case-packing conveyor, where the check valve holds the set circuit against backflow and the lubricator keeps the cylinder seals and valve spools working over long shifts.
Start with the port and size step: the GC range steps through sizes 200, 300, 400 and 600, and the right size depends on the air demand of the circuit downstream, so match the 3/8 in G-thread connection on this unit to your supply line and ask us to check the flow curves against your consumption. Then choose the drain: differential-pressure (as fitted here), automatic, or manual. Choose the filter grade - 40 um standard or 5 um with code W - if finer particulate removal is needed. Gauge scale can be MPa, psi or bar; this unit carries the square gauge in psi. Thread is PT as standard with G and NPT as order options, and brackets are optional on the individual units. 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 the GC series as curves, not as a single rated figure, so we do not quote one number. Send us your line pressure and the air consumption of the equipment downstream, and we will confirm the flow and sizing from the datasheet on request.
The GC prefix means three separate units - filter, regulator and lubricator - assembled as one combination, so it both cleans and dries the air, holds a set pressure, and adds oil mist for downstream air tools and cylinders. This unit is the size 300, 3/8 in G-thread version with a differential-pressure drain, the standard 40 um element, a square psi gauge and a fitted check valve; a two-unit GFC set omits the lubricator if you do not need oil in the line.
