The AirTAC GC30015MLF2K AirTAC F.R.L. Unit 1/2 in PT Low-Pressure 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 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30015MLF2K is an AirTAC GC300 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 300-size unit with PT1/2 (1/2 in) ports. The filter section removes water and particulate down to 40 um, the manual-drain bowl lets you discharge collected condensate by hand, and the lubricator meters oil mist into the air line to keep downstream air tools and actuators running smoothly. The regulator is the low-pressure type and carries a fitted square gauge reading in psi, and a reverse/check valve is fitted to hold the line against backflow.
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with a choice of PT, G (BSPP) or NPT threads, manual or automatic drain, a 5 um filter element (code W), gauge scale options and reverse/check valve. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures against 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.

Dropped off a 1/2 in PT plant air main, the GC30015MLF2K filters, regulates and lubricates the supply feeding a bay of impact wrenches and nutrunners, with the psi gauge giving operators a local pressure readout.
On a carton-forming and sealing line, the unit conditions the air feeding cylinder-driven clamps and pushers, with the lubricator oil-misting the line so valve spools and cylinder seals run on lubricated air.
Feeding the clamping circuit of a CNC fixture setup, the combination removes water and 40 um-plus particulate, holds a steady low-pressure setpoint on the regulator, and the check valve helps hold the circuit against backflow.
Step up or down through the 200 / 300 / 400 / 600 sizes to match the port and flow your line needs; this 300 unit sits at PT1/2. Choose the drain to suit access: manual (this unit) for a supervised drain point, automatic for unattended condensate discharge, or differential-pressure as the default. The standard element is 40 um; specify 5 um (W) where finer particulate removal matters. Gauge scale is selectable (MPa, psi or bar) and this unit ships with the square gauge in psi; the reverse/check valve (K) is already fitted. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
One honest note on sizing: filter flow is published as curves, not a single rated figure, and the low-pressure regulator's adjustment range is not published in the data we hold. Ask us to confirm both against your application 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 filter flow as curves rather than a single rated figure, so we do not quote one number here. Tell us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet curves on request. The same applies to the low-pressure regulator's adjustment range, which is not published in the data we hold.
This unit has a manual drain: condensate collected in the filter bowl is discharged by hand, which suits supervised drain points. If the unit will sit unattended, order the automatic drain instead, or the differential-pressure drain as the default. You can also step the filter grade to 5 um (code W), change the gauge scale between MPa, psi and bar, and order G (BSPP) or NPT threads in place of the PT standard.
