The AirTAC GC30010MLF2WGK AirTAC F.R.L. Combination, G3/8, 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built as one air-preparation set. This GC30010MLF2WGK is the size 300 unit with a G3/8 (BSPP) port. The filter carries the fine 5 um element (code W; the standard element is 40 um), the bowl is manual drain and made of polycarbonate (PC), and the regulator is the low-pressure type. The set includes an embedded square 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).
This is a genuine AirTAC part. The GC family covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for thread (PT standard; G and NPT to order), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with W), gauge scale (MPa, psi or bar) and a reverse valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and the full datasheet 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. 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.

Feeding gripper and pick-and-place actuators on a robot cell: the 5 um element strips water and fine particles before the low-pressure regulator reduces the supply to the pressure the small actuators run at, and the lubricator carries an oil mist into the valve-and-cylinder circuit.
Cartoning and case-packing machines cycle pneumatic cylinders continuously: the lubricator keeps oil mist in the supply, the filter protects the directional valves, and the fitted reverse (check) valve blocks backflow in the prep set.
A maintenance workshop drop feeding impact wrenches and air ratchets: the regulator holds a stable working pressure at the tool, the 5 um filter keeps rust and pipe scale out of the tools, and the oil mist keeps their internal lubrication topped up.
Start with size and port: the GC range steps through 200, 300, 400 and 600 with increasing port size, and the size 300 here carries a 3/8 in port - pick the step against the flow your line needs, which we confirm from the published curves on request. Then set the drain: manual (this unit, code M) is emptied by hand, while automatic and differential-pressure drains remove condensate without attention. Filter grade is 5 um here (W) against the 40 um standard. The regulator is the low-pressure type; the exact adjustment range for that variant is not published in our material, so confirm it with us. The gauge is the embedded square type scaled in psi (MPa and bar scales also exist). Thread is G (BSPP) on this code; PT is the standard thread and NPT is available to order. A mounting bracket is included.
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 one number. Tell us your line pressure and the flow your application needs, and we will confirm the sizing from the datasheet curves before you order.
This code carries the L option, so the GC300 regulator in the set is the low-pressure type rather than the standard version. The exact adjustment range for the low-pressure variant is not published in the material we hold, so ask us to confirm it against your set pressure before ordering.
