The AirTAC GC60020MLF2GK AirTAC F.R.L. Unit G3/4 Low-Pressure 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 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC60020MLF2GK is an AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment train. This 600-size unit carries G3/4 ports with G (BSPP) thread, and its configuration is fully decoded from the code: a manual drain on the filter bowl, the standard 40 um filter element, a low-pressure regulator type, an embedded square gauge scaled in psi, a fitted reverse/check valve, and the mounting bracket included. It filters water and particulate from the compressed air, regulates downstream pressure, and adds oil mist to lubricate downstream air tools and actuators.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filter grades, standard or low-pressure regulation, gauge scales in MPa, psi or bar, and an optional reverse/check valve. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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.

|---|---|
| 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. |
| (blank) | Filtering grade 40 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.

Feeding filtered, regulated and lubricated air to a spray-booth or coating line, where water and particulate must be stripped out, pressure held steady at a low setpoint, and downstream spray guns kept oiled.
Conditioning the shop-air feed to a CNC machine or machining centre's pneumatic circuit: clean air for valves, a stable low regulated pressure for clamping, and oil mist for air cylinders and tools.
Supplying treated air to conveyor diverters, packaging machinery and actuator banks, where the check valve holds the circuit against backflow and the lubricator keeps cylinders running smoothly.
The 600 size is the largest step in the GC range, with 3/4-inch ports suited to higher-flow supply lines; step down to 400, 300 or 200 if your line is smaller. This unit is already configured with a manual drain, 40 um filter grade, low-pressure regulator, square psi gauge, check valve and bracket, so the remaining real choices are thread (PT is the standard; G and NPT are order options) and, if your application needs finer filtration, the 5 um (W) element instead of the standard 40 um. Note that the exact regulation range of the low-pressure type is not published in the material we hold, so confirm it with us if your setpoint tolerance matters. Flow 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 GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line size and demand and we will confirm the flow from the datasheet for this exact 600-size, G3/4 unit before you order.
The M in the code selects a manual drain, so condensate in the filter bowl is released by hand rather than automatically - a good fit where the unit is checked as part of a routine. F2 selects the embedded square gauge scaled in psi; MPa or bar scales and an external round gauge are available as order options.
