The AirTAC GC30010MLC2WK AirTAC F.R.L. Combination, PT3/8 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30010MLC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 300 unit has a PT3/8 (3/8 in) port with standard PT thread, a 5 um filter element (the finer of the two published grades), a manual drain on the filter bowl, and a low-pressure regulator type. The round gauge fitted to this code reads in psi, and a reverse/check valve is fitted. The filter bowl is polycarbonate (PC), and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600, with port options, drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um with W), gauge styles and scales, and G or NPT thread variants available to order. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application on request.

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.

|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Clean, regulated and oil-mist-lubricated air for spray guns and air-assisted applicators, where the 5 um element and a stable low-pressure setting protect finish quality.
Feeds cylinders and pneumatic actuators on wrapping, sealing and labelling machines from a single conditioned air point, with the check valve holding the circuit if supply dips.
Conditions the air feeding clamps, grippers and small presses on a workshop manifold, with the lubricator keeping downstream cylinders and valves running smoothly.
Step up or down through the GC sizes (200/300/400/600) to match the port and the flow your line needs; this code is size 300 at PT3/8. Choose the drain to suit access: manual (as here) needs someone to open the drain, while automatic and differential-pressure types handle condensate without attention. The 5 um element in this code suits air that feeds sensitive components; the 40 um standard grade is the everyday choice. Gauge style and scale are selectable (embedded square as standard, external round optional, in MPa, psi or bar - this code carries a round psi gauge), and the K code adds a reverse/check valve. PT is the standard thread; G (BSPP) and NPT are orderable options.
Flow for this family is published as curves, not a single rated figure, 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so there is no one number we can quote honestly. Tell us your working pressure and the air your equipment consumes, and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code sets a manual drain: condensate collected in the polycarbonate filter bowl is released by hand, which suits stations that are checked as part of a routine. The L sets the low-pressure regulator type, intended for circuits that run below the standard range; the exact adjustment range for this type is not published, so we confirm it on request. The C2 adds a round gauge reading in psi, and K fits a reverse/check valve.
