The AirTAC GC600-20G AirTAC F.R.L. Unit, G3/4, 5 um, Manual Drain 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 PT3/4" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC600-20G is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, so compressed air is cleaned of water and particulate, held at a set working pressure, and carries a fine oil mist to downstream equipment. This size-600 configuration is built around a G3/4 (3/4 inch) G-thread port, uses the fine 5 um filter element (code W), and has a manual drain on the bowl, so an operator opens the drain valve to release collected condensate. The regulator is the low-pressure type, and the set carries the embedded square gauge scaled in psi, plus a reverse/check valve. The size-600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 inch up to 1 inch, with choices of drain type, filter grade (40 um standard, 5 um optional), gauge scale, thread form (PT standard; G and NPT as order options) and reverse/check valve. Flow is published in the catalogue as curves rather than a single rated figure, so ask us and we will confirm the flow and datasheet 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. 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.
| GC600 | G-series F.R.L. combination, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GF600-20 filter, GR600-20 regulator and GL600-20 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 at the take-off point of a plant air ring main, the set cleans, regulates and lubricates the supply feeding impact wrenches, nut runners and pneumatic clamps along the assembly line.
Mounted ahead of the actuated valves and cylinders on a bottling or cartoning conveyor, it conditions the air so packaging machinery receives clean, regulated, lubricated supply through a 3/4 inch line.
Placed upstream of large pneumatic valve actuators on a process skid, it removes water and fine particulate, holds the actuator supply pressure steady and keeps the actuator internals lubricated.
Size 600 with a G3/4 port sits at the top of the GC range, so step up or down (200/300/400/600) according to the pipe size and air demand of the line; the larger the size, the larger the port and the greater the flow capacity. This unit already carries the 5 um fine element (code W) instead of the 40 um standard, a manual drain instead of the differential-pressure default, and a square gauge scaled in psi; an external round gauge and MPa or bar scales are alternatives. The regulator here is the low-pressure type, so confirm the working-pressure band you need before ordering. Thread is G as coded; PT is the standard and NPT is also available to order. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
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 GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can state. Send us your line pressure and air demand and we will confirm the flow figures from the datasheet on request.
The M in the code GC60020MLF2WGK specifies a manual drain, so condensate is released by opening the drain valve rather than automatically; the W specifies the 5 um fine filter element instead of the 40 um standard. Both are catalogue options, and the differential-pressure drain and 40 um element are available on other GC600 variants if your application prefers them.
