The AirTAC GC300C08AC2 AirTAC F.R.L. Combination Unit 1/4" PT 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 GC300C08AC2 is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 300-size set. This configuration carries PT1/4 (1/4 in) ports on the PT thread standard, a 40 um filter element, an automatic drain on the filter bowl, and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filter grades, and gauge scale options in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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-C0 filter, GR300-C0 regulator and GL300-C0 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 air cylinders, grippers and impact tools at a single assembly station: the filter removes water and particulate, the regulator sets working pressure, and the lubricator carries oil mist downstream to extend tool and seal life.
Conditioning the air supply to packaging machinery actuators and diverters, where the automatic drain handles condensate on a line that runs unattended and the psi gauge lets operators verify set pressure at a glance.
A point-of-use F.R.L. at a workshop air drop serving impact wrenches, grinders and drills: clean, regulated and lubricated air at the tool, with the included bracket fixing the set to the drop frame.
Start with the port step: the 300 size with 1/4 in PT ports suits mid-range actuator and tool circuits, while 200, 400 and 600 sizes step port and flow capacity up or down - match the size to the air demand of the circuit rather than the pipe alone. Choose the drain to match access: automatic drain (as on this unit) suits installations that are not checked daily, manual drain suits attended stations, and the differential-pressure default drains on load. Filter grade is 40 um standard; specify the W option for 5 um where finer protection is needed. Gauge scale is selectable (MPa, psi or bar) - this unit ships with a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options; a bracket is included as standard.
Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering - we will pull the datasheet figure for the exact size and condition you specify.
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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for this family as curves, not as a single rated figure, so there is no one rated-flow number we can quote honestly. Tell us your operating pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The A in this model code specifies an automatic drain, which ejects collected condensate without an operator opening the bowl - useful on lines that run unattended. The GC family is also available with manual drain or with the differential-pressure default drain; choose the option that matches how often the installation is checked.
