The AirTAC GC30015AF2K AirTAC F.R.L. Combination, PT1/2, 3-Piece 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015AF2K is a three-piece AirTAC G-series F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, set up as a complete air-preparation train for a 1/2 in line. This configuration is decoded as follows: PT1/2 ports with PT thread as the standard (G and NPT are order options), an automatic drain on the filter bowl, the standard 40 um filter element, a fitted embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts over 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The bowls on the filter and lubricator are PC (polycarbonate) at this size; only the 600 size uses aluminium alloy.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with a choice of port size and thread, drain type, 5 um (code W) or 40 um filtration, gauge scale, and reverse/check valve. Flow figures are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing for your application 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: GF300-15 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 clean, regulated and lubricated air to the tool-clamp and pallet-change circuits of a CNC machining centre, where the 1/2 in line serves multiple actuators from one preparation point.
Conditioning shop air ahead of spray booths and air-driven applicators on an automotive trim line, with the automatic drain handling condensate and the regulator holding a steady set pressure.
Supplying treated air to gripper cylinders and diverters on a carton case-packing conveyor, where the lubricator keeps cylinder seals working and the check valve holds downstream pressure.
Choose the size step (200/300/400/600) and port to match the line and the flow your application needs - this unit is the 300 size with PT1/2 ports. Pick the drain type where a bowl is fitted: automatic (this code), manual, or the differential-pressure default. Select 40 um standard filtration or the 5 um W option if finer particulate removal is required. The gauge comes as an embedded square gauge; external round gauges are optional, with MPa, psi or bar scales - this code carries a square psi gauge. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. A reverse/check valve is fitted on this unit (code K), and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not as a single rated figure, so we do not quote a flow number here. Ask us to confirm the datasheet and check the 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 the GC series as curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your line size and application and we will confirm the datasheet and check the sizing against your requirement on request.
The A in GC30015AF2K selects the automatic drain on the filter bowl, so condensate is expelled without manual attention; manual and differential-pressure drains are available on other codes. The trailing K means a reverse/check valve is fitted, holding downstream pressure if the supply drops.
