The AirTAC AirTAC GC600C20AF2WK F.R.L. Combination 3/4 in PT 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 AirTAC GC600C20AF2WK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This size 600 unit is ported PT3/4 and carries the 5 um filter element (code W) with an automatic drain, so condensate is expelled from the filter bowl without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the fitted square gauge reads in psi. A reverse/check valve (code K) is fitted downstream of the regulator, holding downstream pressure if the supply line is depressurised. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 600 the filter and lubricator bowls are aluminium alloy.
This is a genuine AirTAC part. The GC range is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of drain type, filter grade, gauge style and scale, thread form and reverse valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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: 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.

Feeding a spray-booth manifold where operators need one point that removes water and particles at 5 um, holds a stable set pressure for the guns, and delivers a fine oil mist to keep air tools and atomising equipment running through the shift.
Supplying the cylinders and air-actuated clamps on a high-cycle packaging line, where the automatic drain clears condensate without stoppages and the check valve holds the downstream circuit if the plant air is shut off mid-run.
Conditioning the shop-air feed to a machining cell so spindle-tool changers, pneumatic clamps and coolant-spray actuators each receive filtered, regulated and lubricated air from a single 3/4 inch drop.
Start with the port step: this unit is size 600 with a PT3/4 connection, the largest step in the GC range, so match it to the supply line and the total air demand of the machines it feeds; smaller sizes 200-400 cover 1/8 to 1/2 inch ports. Choose the drain type for the filter bowl: automatic (as fitted here) suits unattended installations, while manual and differential-pressure drains are the other catalogue options. The filter grade is 5 um with this W code; 40 um is the standard element if finer filtration is not required. The square gauge here reads in psi; MPa and bar scales and an external round gauge are the alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options. Flow for this series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 curves rather than a single rated figure, so there is no one rated-flow number we can quote. Tell us your inlet pressure, set pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet curves on request before you order.
The W in the code selects the 5 um filter element instead of the standard 40 um element, so finer water and particulate removal is built in. The A code selects the automatic drain, which expels collected condensate from the filter bowl on its own - useful where the unit is mounted in a position that is awkward to reach for manual draining.
