The AirTAC GC300C15MLF2WK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C15MLF2WK is an AirTAC GC-series three-unit F.R.L. combination: a filter, a regulator and a lubricator assembled as one compressed-air preparation set. This configuration is built around a 1/2 in PT port, a 5 um filter element (one grade finer than the 40 um standard) for water and particulate removal, a manual drain on the filter bowl, a low-pressure-type regulator, an embedded square gauge reading in psi, and a reverse/check valve fitted. The filter bowl on the 300 size is polycarbonate, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family spans the 200, 300, 400 and 600 sizes with port options from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and G or NPT threads as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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. 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.

Point-of-use preparation for the compressed air feeding a CNC machining centre's pneumatic clamps and tool-change cylinders: 5 um filtration, a regulated low-pressure supply and oil-mist lubrication delivered at the machine.
Supplying the cylinders and air-driven grippers on a carton packaging or case-sealing conveyor line, where the regulator holds a steady low pressure and the lubricator mists oil into the air stream for the actuators.
A preparation station on an assembly plant's ring main feeding pneumatic hand tools and air cylinders, combining water and particle removal, pressure regulation and lubrication in one 1/2 in connection.
Choose the size and port step to match the air demand of the downstream circuit; this unit is the 300 size with a 1/2 in PT connection. Drain type is a real operating choice: a manual drain (as coded here) needs an operator to bleed collected condensate from the bowl, while the automatic and differential-pressure drain options discharge without attention. Filter grade is 40 um standard or 5 um (code W, fitted here) where finer protection is required. The embedded square gauge is standard with MPa, psi or bar scales, and an external round gauge is optional. Thread is PT as standard on this unit; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included. Flow is published as curves, not a single rating, so 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-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 one number. Tell us your application and we will confirm the sizing and the datasheet flow figures on request before you order.
The M in the code sets a manual drain: an operator opens the drain to bleed collected condensate from the filter bowl, instead of using the automatic or differential-pressure drain options. The W sets the 5 um filter element, one grade finer than the 40 um standard, for better protection of downstream valves and cylinders.
