The AirTAC GC300C15MLC2WG AirTAC F.R.L. 5 um, G1/2, Round Gauge 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 assembled as one set. This GC300 unit is the size 300 frame on a G1/2 (BSPP) port, with a 5 um filter element (the W grade, finer than the 40 um standard), a manual drain on the filter bowl, the low-pressure regulator type (adjustment range confirmed on request), an external round gauge reading in psi, a metal bowl and an included mounting bracket; no reverse/check valve is fitted. It treats compressed air only, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC range runs from size 200 to 600 with ports from 1/8 to 1 inch, and can be ordered with automatic, manual or differential-pressure drains, a 40 um or 5 um element, square or round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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 impact wrenches and nutrunners on an automotive final assembly line: the 5 um element and lubricator look after the tools, the regulator holds the circuit setting, and the manual drain suits a manned cell where bowls are bled each shift.
Supplying cylinders and grippers on a carton case-packing line: filtered, regulated and lubricated air from one G1/2 set, with the round psi gauge letting operators check the line setting at a glance.
Running hold-down clamps and dust-hood cylinders on a panel saw or CNC router in a dusty woodshop, where the 5 um grade keeps fine particulate out of the valves and the included bracket gives a tidy machine-mounted point of use.
Choose the size by the port and flow step: 200, 300, 400 or 600, with ports from 1/8 to 1 inch - here size 300 on G1/2. Pick the drain to match maintenance: manual (this unit) needs an operator to bleed the bowl, automatic drains on their own, and the differential-pressure default drains only when the pressure drop calls for it. Filter grade is 40 um standard or 5 um (W) for finer protection - this unit carries the 5 um element. Gauges are an embedded square gauge as standard or an external round gauge, scaled in MPa, psi or bar; this one is round, psi. Thread is PT as standard with G and NPT as order options. Flow is published as curves, not a single rating, so 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 a number here. Tell us your line pressure and the air demand of the tools or cylinders downstream, and we will confirm the sizing and flow figures from the datasheet on request.
This unit's filter bowl has a manual drain: an operator opens it to bleed off collected water, which suits attended cells on a regular check routine. The GC series can also be ordered with an automatic drain or the differential-pressure default, and with the 40 um standard element instead of this unit's 5 um grade - ask us when ordering.
