The AirTAC GC300C15MLC2WK 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 GC300C15MLC2WK is an AirTAC GC-series three-piece F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. It cleans compressed air of water and particulate down to 5 um (the W fine-grade element), regulates downstream pressure with the low-pressure type regulator, and adds oil-mist lubrication for downstream tools and cylinders. This 300-size unit is threaded PT1/2 (1/2 in PT; G and NPT are order options), carries a metal bowl with manual drain, an external round gauge scaled in psi, a fitted reverse/check valve, and includes the mounting bracket. 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 available in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread standard and reverse valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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-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 a bank of pneumatic impact wrenches and nutrunners at a final-line assembly station: the 5 um filter keeps moisture and grit out of the tools, the regulator sets working pressure, and the lubricator carries oil mist into the tool motors.
Preparing air for the clamp, pusher and forming cylinders on a carton packaging conveyor, where the reverse/check valve holds cylinder position if plant air pressure drops and the manual drain clears accumulated condensate at shift checks.
Supplying a CNC workholding clamping circuit that needs clean, lubricated, low-pressure-regulated air, with the psi-scaled round gauge giving the operator a direct reading of set pressure at the fixture.
Choose the size and port step against the air demand of the circuit: this is the 300 size with a 1/2 in PT port; larger sizes carry larger ports and more flow. This configuration is specified with a manual drain, so an operator drains the bowls on a routine; if unattended drainage is needed, ask about the automatic or differential-pressure drain variants. The 5 um W-grade element is the finer filtration choice where downstream valves and instruments need cleaner air than the 40 um standard element provides. The round gauge is scaled in psi; square embedded gauges and MPa or bar scales are alternatives. The low-pressure type regulator is intended for circuits working below standard regulator ranges - the exact adjustment range for this low-pressure configuration is not published, so confirm it with us before ordering. The fitted reverse/check valve holds downstream pressure if the supply fails, and the bracket is included for panel or surface mounting. Flow is published as curves, not a single rating, so send us your application details 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, not as a single rated figure, so we do not quote a flow number here. Tell us your application and air demand and we will confirm the sizing against the datasheet on request.
The L code marks this as the low-pressure type regulator rather than the standard one, intended for circuits working below standard regulator ranges. The exact adjustment range for this low-pressure configuration is not published in our data, so confirm the range with us on request before ordering.
