The AirTAC GC30010LF2WK AirTAC F.R.L. Combination, PT3/8 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 PT3/8" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30010LF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package for compressed air. This configuration is the 300 size with a PT3/8 (3/8 in) port, fitted with a 5 um filter element (the finer of the two published grades), a differential-pressure drain on the filter bowl, a low-pressure regulator type, an embedded square gauge reading in psi, a reverse/check valve, and a mounting bracket included. The three functions work in sequence: water and particulate are removed first, downstream pressure is set and held, and a fine oil mist is added for air-fed tools and cylinders.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, and choices of drain type, filter grade, gauge scale and thread form (PT standard, with G and NPT as order options). Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure 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: GF300-10 filter, GR300-10 regulator and GL300-10 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.

A filtered, regulated and lubricated air drop feeding machining-centre tool changers and clamping cylinders, with the 5 um element protecting fine-valve pilot circuits on the shop floor.
A conditioning station ahead of the pneumatic cylinders and grippers on a carton-forming and sealing conveyor, where the check valve holds the set circuit if upstream supply drops.
A wall-mounted F.R.L. feeding air impact drivers, nutrunners and air motors at an assembly bench, with the lubricator carrying oil mist to keep the tools running.
Start with the port step: the 300 size here carries a 3/8 in PT port, and larger sizes carry larger ports and more flow, so match the size to the air demand of the circuit rather than only to the existing pipe. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Next, choose the drain: this unit uses the differential-pressure drain (the default), with automatic and manual drains available in the family. The filter grade is 5 um here (code W); the standard grade is 40 um if finer filtration is not required. The regulator on this unit is the low-pressure type; its exact adjustment range is not published, so confirm it with us if your set point matters. The gauge is the embedded square type reading in psi, with MPa or bar scales and an external round gauge available as options. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included, and the reverse/check valve is fitted on this code.
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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated number, so we do not quote one figure. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The W in the code selects the finer 5 um element instead of the standard 40 um grade, which suits circuits with sensitive pilot valves. The L selects the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us if your set point is critical.
