The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010AF1WK) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT3/8" ports, a 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
This GFC300-10A-F1WK combines AirTAC's two-unit F.R.L. concept - filter regulator plus lubricator - with the 5 um (W) filtration element and a fitted reverse-flow (check) valve for circuits where air must not pass back toward the supply. It is the 300 size with PT 3/8 in. ports, an automatic drain on the filter bowl and the embedded square gauge reading in MPa. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) at up to 1.0 MPa (145 psi) inlet; medium is compressed air, temperature range is -5 to 70 C (non-freezing), and both bowls on this 300 size are polycarbonate (PC).
This is a genuine AirTAC part. The W and K codes are catalogue options on the GFC two-unit set, which also comes in 200, 300, 400 and 600 sizes with 1/8 to 1 in. ports, differential-pressure or manual drains, the 40 um standard element, embedded square or external round gauges in MPa, psi or bar scales, and PT (standard), G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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 set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR300-10 filter regulator and GL300-10 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

A prepared-air point for impact wrenches, ratchets and air screwdrivers on a maintenance bench, with the 5 um element protecting the tools and the check-valve option where the branch must resist backflow.
Regulated, filtered and lubricated air for clamping fixtures where the fitted reverse-flow (check) valve is specified because the circuit must not push air back toward the header.
Feeds the valve manifold of a dispensing or pick-and-place cell: fine 5 um filtration ahead of the valves, a fixed set pressure from the regulator, and lubrication for the actuator package.
This variant stacks two choices: the 5 um W element for finer filtration and the K reverse-flow (check) valve where backflow toward the supply must be prevented - omit either by ordering the F1W or F1K code. Size stays at 300 with 3/8 in. PT ports; move to 200 for compact points or 400/600 for larger ports and more flow. The automatic drain ejects condensate without attention, and the embedded square gauge reads MPa, with psi/bar scales and an external round gauge as options.
Flow for the G series is published as curves, not a single rating, so give us your application's flow and pressure 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-10 filter regulator on its own.
G-series flow is published by AirTAC as performance curves, not as a single rated figure, so we do not state a number here. Send us your required flow and working pressure and we will confirm the size and supply the datasheet on request before you order.
This model has PT 3/8 in. ports as standard. If your piping uses BSPP (G) or NPT, those are catalogue thread options available on the same size - mention it at the enquiry stage and we will confirm the matching code and its datasheet on request.
