The AirTAC GC30015MLF2GK AirTAC F.R.L. Combination, G1/2 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 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment set. This configuration, GC30015MLF2GK, is the size 300 unit with a 1/2 in port threaded G (BSPP). The filter element is the standard 40 um grade with a manual drain on the bowl, so condensate is released by hand rather than automatically. The regulator is the low-pressure type and carries an embedded square gauge scaled in psi. A reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in up to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 40 um standard or 5 um (code W) filter grade, and gauge scales in MPa, psi or bar. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the 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. 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.

Installed at the drop from a plant air main to condition the supply for a production bay: the filter removes water and particulate, the low-pressure regulator sets the working pressure read on the psi gauge, and the lubricator mists oil downstream to pneumatic tools and cylinders.
Mounted on the air supply to a conveyor or packaging machine, this three-unit set keeps the actuators supplied with clean, regulated and lubricated air, with the manual drain emptied during scheduled checks and the check valve holding the set pressure against supply dips.
Fitted by machine builders and maintenance teams on new or retrofitted pneumatic panels, where the bracket-mounted combination conditions the whole machine supply at 1/2 in, and the psi-scaled square gauge gives operators a direct pressure readout at the panel.
Start with the port step: size 300 with a 1/2 in G-threaded port suits lines sized accordingly, and the larger GC sizes (400, 600) carry larger ports and more flow capacity - match the size step to the air demand of the circuit. Choose the drain type for the filter bowl: manual (this unit) means an operator drains the bowl by hand, while automatic and differential-pressure drains remove condensate without intervention. The filter grade here is the standard 40 um; the 5 um W grade is available where finer particulate removal is needed. The embedded square gauge on this unit reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) as ordered, with PT standard and NPT available as options; a mounting bracket is included. Note that this is the low-pressure regulator type, so confirm the control range suits your line. Because flow is published as curves rather than a single rating, 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line size and air demand and we will confirm the flow figures from the datasheet for this exact 1/2 in, size 300 unit before you order.
The M in the code sets the filter bowl to a manual drain: condensate is released by hand during maintenance instead of automatically. The L code marks the low-pressure regulator type, whose control range is not published in the standard tables - ask us to confirm the adjustment range against your working pressure before ordering.
