The AirTAC GC30010C2WGK AirTAC F.R.L. Combination Unit - 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 PT3/8" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010C2WGK is a genuine AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack for compressed-air lines. This 300-size unit is built for a 3/8 in G-thread port, and the configuration carries a fine 5 um filter element (the standard element is 40 um; this one is ordered with the W grade), a differential-pressure drain on the filter bowl, a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi), an external round gauge with a psi scale, a reverse/check valve, and the mounting bracket included. The filter and lubricator bowls on this size are polycarbonate (PC).
This is a genuine AirTAC part. The GC family is offered 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 scale, thread (PT standard; G and NPT as order options) and check valve. Published flow data appears as curves rather than a single rated figure, so ask us to confirm the datasheet and flow figures 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: GF300-10 filter, GR300-10 regulator and GL300-10 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 chucks, clamps and blow-off guns on a machining centre: the 5 um element protects spool valves from fine particulate, the regulator holds a steady set pressure, and the lubricator mists oil to the shop's air tools.
Supplying the pneumatic cylinders and vacuum generators on a carton-forming and sealing line, where the check valve keeps the circuit pressurised through brief supply dips and the psi gauge lets operators verify set pressure at a glance.
A point-of-use F.R.L. station for impact wrenches, ratchets and air rammers at a vehicle assembly cell: clean, regulated, lubricated air at each drop, with the differential-pressure drain keeping the bowl clear without daily manual draining.
Choose the size and port step against the air demand of the line: this unit is a 300 with a 3/8 in port, one step up from the 200/1/4 in class and one below the 400/1/2 in class. The 5 um element in this unit suits downstream equipment that needs finer water-and-particulate removal than the standard 40 um grade; the trade-off is a finer element to keep clean. The differential-pressure drain bleeds the bowl automatically as the pressure differential across the element builds, with no operator attention. The round psi gauge is the external option - the embedded square gauge is standard, and MPa or bar scales are also available. Thread here is G (BSPP); PT is the standard thread and G or NPT are catalogue options to order. The reverse/check valve holds downstream pressure if the supply drops.
Because AirTAC publishes flow as curves rather than a single rated number, we do not quote a rated flow figure here. Send us your application's air demand and we will confirm the sizing against the datasheet curves 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not state a rated flow number here. Send us your line pressure and the air demand of the equipment you are feeding, and we will confirm the flow figures from the datasheet curves for this exact 300-size, 3/8 in unit before you order.
The W code in GC30010C2WGK orders the fine 5 um element instead of the standard 40 um grade, for tighter water-and-particulate removal ahead of sensitive valves and tools. The K code fits a reverse/check valve, which holds downstream pressure if the upstream supply is interrupted. The differential-pressure drain on the filter bowl is automatic in operation, and the round gauge reads in psi.
