The AirTAC GC600C20F2WK AirTAC F.R.L. Combination, PT3/4, 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600C20F2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator working together to remove water and particulate, hold a set downstream pressure and add oil mist to the air supply. This 600-size unit is fitted with a 3/4 in PT port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain on the filter bowl, and a square pressure gauge reading in psi. A reverse/check valve is fitted, and the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. On this 600 size, the filter bowl is aluminium alloy.
This is a genuine AirTAC part. The GC line is offered in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual draining, 40 um standard or 5 um (W) filtration, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, 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. 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: GF600-C2 filter, GR600-C2 regulator and GL600-C2 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 where the main header leaves the compressor room, the filter strips water and 5 um particles, the regulator holds a steady header pressure, and the lubricator feeds oil mist to every downstream air tool on the floor.
Mounted ahead of the valve manifold on a filling or cartoning line, the unit keeps cylinder pressure stable through shift-long cycling, drains condensate automatically, and lubricates the actuators that index, cap and seal.
Fitted at the drop to a workholding or pneumatic press station, the regulator holds the clamping force setting, the 5 um element protects precision valves from fouling, and the check valve holds the set pressure if the main supply drops.
Start with the port step: this unit is 600 size with a 3/4 in PT port, the largest in the range, so match it to line size and required flow - we can confirm the flow curve against your demand before you order. The 5 um element (code W) suits air that feeds sensitive valves, cylinders or instruments; the 40 um standard grade is fine for general shop-air protection. The differential-pressure drain bleeds the bowl automatically as pressure builds, with no daily manual draining. The fitted square gauge reads in psi; MPa and bar scales are available if you prefer. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and the check valve (K) holds downstream pressure if the supply line is vented. A mounting bracket is included.
Quick checklist
The aluminium-alloy bowls on the GC600 suit harsher environments than PC bowls. 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 GR600-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for the GC series as performance curves, not as a single rated number, so there is no one Cv or l/min figure we can quote honestly. Send us your line pressure and air demand and we will confirm the flow from the datasheet curve for this 600-size, 3/4 in unit before you order.
The GC filter takes either the standard 40 um element or the finer 5 um element, which is what the W in this model code selects. The 5 um grade is the right choice when the air feeds precision directional valves, cylinders with close tolerances, or instrumentation, where finer particulate would otherwise cause sticking and wear. For general tool-air protection, the 40 um grade does the job at lower element cost.
