The AirTAC GC30015LC2K AirTAC F.R.L. Combination, PT1/2, 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30015LC2K is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter to remove water and particulate, a regulator to set working pressure, and a lubricator to feed oil mist downstream. This 300-size unit is threaded PT1/2 (1/2 in, PT standard). The filter element is the standard 40 um grade with a differential-pressure drain, the regulator is the low-pressure type for circuits that run at reduced set pressures, and a round gauge on a psi scale is fitted so operators can read the set pressure directly. A reverse/check valve is fitted to hold downstream pressure, and the mounting bracket is included.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include 5 um filtration (code W), automatic or manual drains, G or NPT threads, and alternate gauge scales. Flow is published as curves rather than a single rated figure, 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.

Feeds filtered, regulated and lubricated air to the gripper and clamp cylinders on a robotic handling cell, with the psi gauge letting operators verify the set pressure at the cell.
Conditions the air supply for the stopper, pusher and gating cylinders along a bottling or canning conveyor, where the check valve helps hold downstream pressure if the supply dips.
Supplies clean, pressure-controlled, lubricated air to the tape-head and flap-fold cylinders on a carton-sealing packaging machine running at reduced set pressures.
Start with the port step: the 300 size carries PT1/2, so match it to your main air line and the flow your circuit needs - larger sizes (400, 600) move more air at the same pressure. Choose the drain to suit access: this unit uses the differential-pressure drain (default); automatic (A) or manual (M) drains are available if the installation calls for them. The 40 um element is the standard grade; specify W for 5 um where finer particulate removal matters. The fitted round gauge reads in psi; square gauges and MPa or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included.
Because this is the low-pressure (L) regulator type, confirm its adjustment range suits your set pressure - the exact range for this variant is not published, so ask us to confirm it from the datasheet. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing 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 flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air your equipment consumes, and we will confirm the correct size from the datasheet curves on request before you order.
C2 means a round external gauge is fitted with a psi scale (MPa and bar scales are alternatives), and K means a reverse/check valve is fitted to help hold downstream pressure. The unit also carries the standard 40 um filter element, a differential-pressure drain, the low-pressure regulator type, and an included mounting bracket.
