The AirTAC GC300C08C2GK AirTAC 3-Piece F.R.L. G1/4, Psi 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 GC300C08C2GK is a three-piece AirTAC F.R.L. combination - separate filter, regulator and lubricator assembled as one unit - for G1/4 (1/4 in) lines. This configuration carries a 40 um filter element with a differential-pressure drain, a standard regulator adjustable 0.15-0.9 MPa (20-130 psi), a round gauge scaled in psi, a reverse/check valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls on the 300 size are PC (polycarbonate); only the 600 size uses aluminium alloy.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in. Across the series you can order automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

Feeds filtered, regulated and lubricated air to the pneumatic clamps and tool-change cylinders on a machining centre, with the check valve holding the set circuit condition against upstream fluctuations.
Conditions the air supply to the flap-fold and taping cylinders on a carton-sealing conveyor, keeping water and debris out of the valves while the lubricator mists oil to the actuators.
Serves as the point-of-use F.R.L. on a bottling line drop, delivering clean, pressure-regulated and lubricated air to the filler and capper actuator circuits from the plant ring main.
Start with the size and port: the 300 size with its 1/4 in port is one step in a range that runs from 200 (1/8 in and 1/4 in) up to 600 (1 in), and the right step depends on the air your line consumes - we can check the published flow curves against your demand before you order. Then set the options that this family lets you decode: drain type (differential-pressure as here, or automatic or manual), filter grade (40 um standard, 5 um with W), gauge and scale (the embedded square gauge is standard; an external round gauge in MPa, psi or bar is optional), thread (PT is the standard; G and NPT are catalogue options), and bracket. The K code here adds a reverse/check valve. Flow is published as curves, not a single rating, so please 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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can state. Send us your line pressure and air demand and we will confirm the flow figures from the datasheet for this exact model before you order.
The trailing G in GC300C08C2GK means G (BSPP) parallel threads on the 1/4 in ports. PT is the standard thread for the series, and G and NPT are catalogue options you order by code, so choose the one that matches your fittings and specify it when ordering.
