The AirTAC GC30015MLF2WK 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30015MLF2WK is an AirTAC GC300 three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one supply package. It cleans compressed air of water and particulate down to 5 um (the W fine-grade element), regulates downstream pressure with the low-pressure type regulator, and adds oil-mist lubrication for downstream air tools and actuators. This configuration has PT1/2 ports (PT thread as standard), a manual drain on the filter bowl, a polycarbonate bowl, an embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain choices, filter grades and gauge scales. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures on request before you order.

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.

Feeding a production hall's pneumatic drop lines that supply impact wrenches, nut runners and air ratchets: the 5 um element stops water and swarf reaching the tools, the regulator holds a steady setpoint, and the lubricator carries oil mist to the tool motors.
Conditioning the supply to a machining centre's air-assisted functions such as tool-change cylinders, clamping fixtures and chip ejection, where clean, regulated, lubricated air keeps the machine's own valves and cylinders working reliably.
Supplying the cylinders and air-operated valves on a carton-forming and case-sealing line, where the filter removes line moisture before it reaches the valves, the regulator pins the actuator speed setpoints, and the lubricator reduces seal and bore wear.
Choose the size and port step against the air consumption of the machines the unit will feed: this GC300 carries PT1/2 ports, one step up from GC200. Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering. This unit pairs a 5 um fine filter element with a manual drain - choose manual when someone is on site to bleed the bowl routinely, or ask about automatic or differential-pressure drain variants. The low-pressure type regulator suits lower setpoint work; we confirm the exact adjustment range on request. The fitted square gauge reads in psi (MPa and bar scales are also available), the reverse/check valve holds downstream pressure on supply loss, and PT is the standard thread with G (BSPP) and NPT available as order options.
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 the GC series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and the air consumption of the equipment you want to feed, and we will confirm the flow curve and check the GC300 sizing against your application before you order.
The M in the code selects a manual drain, so the filter bowl is bled by hand at intervals - a good fit where an operator is on site; automatic and differential-pressure drain variants exist for unattended installs. The W selects the 5 um fine filter element instead of the 40 um standard, and K means a reverse/check valve is fitted to hold downstream pressure if the supply drops.
