The AirTAC GC30015C2WGK AirTAC F.R.L. Combination, G1/2, 5 um 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015C2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-preparation set. This configuration is built in the 300 size with G1/2 ports, carries the W-code 5 um filter element for finer removal of water and particulate than the standard 40 um grade, and uses a differential-pressure drain on the filter bowl. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and this unit is fitted with an external round gauge reading in psi. A reverse/check valve (code K) is fitted, the mounting bracket is included, and the bowls are polycarbonate. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes covering port sizes from 1/8" to 1", with options including drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard, G and NPT to order) and reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures 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.

Feeds filtered, regulated and lubricated air to pneumatic clamps, tool-change cylinders and chip-clearing blasts on a CNC machining centre, with the 5 um element protecting fine-tolerance valves.
Supplies a workstation of impact wrenches, nutrunners and air ratchets on an automotive assembly line, keeping the regulator set point stable and delivering oil mist for tool life.
Prepares air for carton-forming and case-sealing cylinders along a packaging conveyor, where clean, dry, lubricated air keeps the sealing sequence consistent shift after shift.
Sizing a GC combination starts with the port step: the 300 size shown here carries G1/2 ports, and the GC family steps through 200, 300, 400 and 600 as port size and flow capacity rise. Match the size to the air demand of the downstream circuit, then choose the drain: differential-pressure (the default on this unit), automatic for unattended draining, or manual where an operator checks the bowl. Filter grade is 40 um standard or 5 um with the W code - this unit carries the 5 um element, the right choice where finer particulate removal matters. Gauge options are an embedded square gauge or an external round gauge, with MPa, psi or bar scales; this unit has a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as orderable options - this unit is the G-thread version. A reverse/check valve (K) holds downstream pressure if the supply drops, and the bracket is included.
One honest note before ordering: AirTAC publishes flow as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application's air demand and we will confirm the correct size and the datasheet figures 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 there is no one rated flow number we can honestly quote. Tell us the air demand of your circuit and we will confirm the sizing and the datasheet flow figures for the GC300 at G1/2 on request before you order.
The W code in GC30015C2WGK selects the optional 5 um element in place of the 40 um standard grade. The finer grade removes smaller water and particulate carryover, which suits downstream precision valves and sensitive actuators; the standard 40 um grade remains available on other GC configurations if coarser protection is all you need.
