The AirTAC GC30015LF2WK AirTAC F.R.L. Combination, PT1/2 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 PT1/2" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015LF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one 300-size unit for 1/2 in PT ports. In use, the filter element removes water and particulate down to 5 um (the finer W grade, versus the 40 um standard), the low-pressure-type regulator holds a stable downstream setting, and the lubricator meters oil mist into the air line. This configuration carries the differential-pressure drain on the filter bowl, a square pressure gauge reading in psi, a reverse/check valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. The bowls on the 300 size are PC (polycarbonate).
This is a genuine AirTAC part. The GC family is offered in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as order options) and reverse valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

Feeds filtered, regulated and lubricated air to the tool-changer, clamps and pneumatic actuators on a CNC machining centre, with the 5 um element protecting fine control valves on the machine's air train.
Supplies the diverters, sealers and pusher cylinders on a carton packaging line, where the lubricator keeps cylinder seals running smoothly and the low-pressure regulator suits circuits set well below full line pressure.
Installed as a point-of-use F.R.L. on drop lines serving looms and winding machines, conditioning the shop air at each machine and draining accumulated condensate automatically via the differential-pressure drain.
Start with the port step: this unit is 300 size with a 1/2 in PT port; step up to 400 or 600 if the line needs more flow capacity, or down to 200 for compact supply points. Filter grade is your next choice: the W code here selects the 5 um element for finer air, while the blank default is 40 um for general-purpose protection. Drain type on the filter bowl is differential-pressure as standard, with automatic (A) and manual (M) variants available. The gauge here is the embedded square type reading psi; an external round gauge with MPa, psi or bar scale is optional. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included. Note this is the low-pressure regulator type (L), and a reverse/check valve (K) is fitted. Because flow is published as curves and not a single rating, send us your application details 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 of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure and the flow your equipment needs, and we will confirm the sizing against the datasheet on request before you order.
The W code in GC30015LF2WK selects the optional 5 um element instead of the 40 um standard, for finer removal of water and particulate ahead of the regulator and lubricator. The K code adds a reverse/check valve, and the L code makes this the low-pressure regulator type. The filter bowl drains by differential pressure, and the square gauge reads psi.
