The AirTAC GC30008MC2WK AirTAC F.R.L. Combination, PT1/4 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 PT1/4" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30008MC2WK is an AirTAC GC300 three-unit F.R.L. combination: a separate filter, pressure regulator and lubricator assembled as one air-treatment set for compressed air. This configuration has 1/4 inch PT ports, 5 um filtration (the fine grade, versus the 40 um standard element), a manual drain on the filter bowl, a standard regulator with a 0.05-0.9 MPa (7-130 psi) adjustment range, a fitted round gauge reading in psi, and a reverse/check valve fitted. The polycarbonate bowls suit the 300 size, and the set includes 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 is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, and with choices of drain type, filter grade, gauge style and scale, thread form (PT standard, G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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: GF300-08 filter, GR300-08 regulator and GL300-08 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.

Installed at a 1/4 inch tool drop, the set cleans the air to 5 um, holds a steady regulated pressure for impact wrenches and nutrunners, and mists oil into the supply to keep tool motors lubricated through the shift.
Mounted on the frame of a packaging or conveyor section, the combination feeds cylinders and air-operated grippers with filtered, regulated and lubricated air, while the check valve holds the circuit's setting if the main supply dips.
On a maintenance shop's point-of-use tap, the three-unit set conditions air for test rigs, air clamps and jigs, with the psi gauge giving operators a direct reading and the manual drain allowing a simple end-of-day bowl blowdown.
Size 300 with 1/4 inch PT ports suits lines where the step up from 200-size flow capacity is needed without moving to 3/8 or 1/2 inch piping; match the port step to your pipe size and required flow. The 5 um element (code W) is the finer choice over the 40 um standard - pick it when downstream valves and cylinders need cleaner air. Manual drain means an operator opens the bowl drain periodically; choose automatic drain if the unit sits where routine draining is impractical. The fitted round gauge reads in psi; an embedded square gauge is the standard alternative, with MPa/psi/bar scales available. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included, and the reverse/check valve holds downstream pressure if the supply drops.
Flow for this family is published as curves, not a single rated number, so we cannot honestly quote one figure here. Send us your application details 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 GR300-08 regulator with a GF300-08 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 to avoid misleading you. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code sets the filter bowl drain to manual: collected water is released by opening the drain at the bottom of the bowl. That suits positions someone visits regularly. If the unit will sit unattended, the same GC300 is available with automatic or differential-pressure draining - and with manual drain the regulator's adjustment range is the wider 0.05-0.9 MPa (7-130 psi).
