The AirTAC GC30010ALF2WK AirTAC F.R.L. Combination PT3/8, 5 um 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010ALF2WK is an AirTAC GC series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set that filters, regulates and lubricates a compressed-air line. This size 300 configuration is threaded PT3/8 (3/8 in), carries the W-grade 5 um filter element instead of the 40 um standard, drains collected condensate automatically, and regulates with the low-pressure type regulator fitted with an embedded square gauge scaled in psi. A reverse (check) valve is fitted and the mounting bracket is included.
It is a genuine AirTAC part, made in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale, thread (PT standard; G and NPT to order) and bracket. Maximum inlet pressure is 1.0 MPa (145 psi) at -5 to 70 C (non-freezing); on this 300 size the bowls are polycarbonate. AirTAC publishes flow as curves rather than a single rating, so ask us to confirm the datasheet figures against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Conditions the air feeding tool-changer and clamp circuits on a machining centre: the 5 um element protects fine pilot valves, the regulator holds the circuit pressure and the lubricator mists oil to the actuated tooling.
Serves carton sealers and case-pack cylinders on a packaging conveyor, where the automatic drain keeps condensate out of the valves during continuous shifts and the check valve holds the set circuit if supply dips.
Fitted at a work-cell drop on an assembly line to filter, regulate at low pressure and lubricate the air feeding hand tools and small cylinders, with the included bracket mounting the set at the point of use.
Size and port step up together: 200, 300, 400 and 600 correspond to larger ports from 1/8 in to 1 in, so choose the size whose flow curve covers your air consumption - we can confirm the curves on request because flow is published as curves, not a single rating. Within this code the real choices are already fixed: automatic drain, 5 um (W) element in place of the 40 um standard, low-pressure regulator, square gauge scaled in psi (MPa and bar scales are selectable across the range), reverse valve fitted, bracket included, and PT thread with G or NPT available to order. If your circuit holds a low regulated pressure, this L-type variant is the relevant choice; confirm its exact adjustment range with us 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 GR300-10 regulator with a GF300-10 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 air consumption and we will confirm the GC300 flow curve and sizing from the datasheet on request.
The code W specifies the optional 5 um filter grade instead of the 40 um standard, giving finer protection for downstream valves and cylinders. The A code specifies the automatic drain, which discharges collected condensate without manual attention. Both are catalogue options across the GF, GFR, GFC and GC families.
