The AirTAC GC300C15MF2WK AirTAC F.R.L. Combination 1/2" PT 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
GC300C15MF2WK is an AirTAC three-piece F.R.L. combination: a filter, a regulator and a lubricator assembled as one air-preparation set. Compressed air enters the filter, which strips water and particles down to 5 um through its W-grade element and releases collected condensate via the manual drain; the regulator then holds downstream pressure anywhere in its 0.05-0.9 MPa (7-130 psi) adjustment range, read on the embedded square gauge scaled in psi; the lubricator finally adds an oil mist for downstream tools and cylinders. A check valve is fitted, the bowls on the filter and lubricator are polycarbonate at this size, and a mounting bracket is included. 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 series is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge scale, thread (PT standard, with G and NPT available as catalogue options) and check valve. We do not quote a single rated flow figure because AirTAC publishes flow as curves; tell us your application and we will confirm the datasheet figures on request.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 0.15 - 0.9 MPa (20 - 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-C1 filter, GR300-C1 regulator and GL300-C1 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 impact wrenches and nutrunners on an automotive assembly line: the filter removes water and swarf, the regulator holds a steady pressure setting, and the lubricator carries an oil mist into the tool air supply.
Supplying cylinders and actuators on a bottling-hall conveyor: 5 um filtration protects directional valves, the regulator keeps clamp pressure repeatable, and the check valve holds the circuit against back-flow.
Point-of-use supply for a CNC machining centre's clamping and chip-clearing circuits: one GC unit filters, regulates and lubricates the entire pneumatic side at the machine.
Size 300 with a PT1/2 port sits mid-range in the GC family (200/300/400/600); step up or down a size when your demand says so - ask us to check it against the flow curve. This unit is built with a manual drain; automatic and differential-pressure drains are catalogue options if the installation is not checked regularly. The 5 um element (code W) suits valves and cylinders that need finer filtration than the standard 40 um. The square gauge is scaled in psi, with MPa and bar scales available as alternatives, and the fitted check valve (K) blocks back-flow through the set. Thread is PT as standard; G (BSPP) and NPT are catalogue options, and a mounting bracket is included. Flow is published as curves rather than a single rating, so send us your demand 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing against the datasheet on request.
The M in the code specifies a manual drain: collected water in the filter bowl is released by opening the drain by hand. If the installation is not visited regularly, the same size is available with an automatic or differential-pressure drain as a catalogue option - ask us for the equivalent code.
