The AirTAC GC600C20LF2K AirTAC F.R.L. Unit 3/4" PT 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600C20LF2K is a genuine AirTAC three-unit F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate down to 40 um, a low-pressure regulator holds your set pressure, and a lubricator feeds an oil mist downstream. This 600-size unit is built with a 3/4 in PT port, a differential-pressure drain on the filter bowl, an embedded square gauge reading in psi, and a reverse/check valve fitted to hold downstream pressure. The aluminium alloy bowls on the 600 size suit demanding installations.
This is a genuine AirTAC part in the largest of the four G-series sizes (200/300/400/600), which also come in smaller ports, PC or aluminium bowls, manual or automatic drains, a 5 um filter grade (code W), and G or NPT thread options. Rated inlet pressure is 1.0 MPa (145 psi) with a working temperature of -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet before you order.

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.

Conditioning the plant air feeding a stamping or forming press cell: the filter strips water and 40 um-plus particulate from the header supply, the low-pressure regulator holds the circuit setpoint, and the lubricator mists oil to the press cylinders.
Supplying treated air to a packaging or bottling line's conveyor actuators and clamp cylinders, where the check valve holds downstream pressure during supply dips and the psi gauge lets technicians verify setpoint at a glance.
Mounted at the garage-air drop of a truck or bus maintenance bay, the 3/4 in F.R.L. feeds impact wrenches and lift controls with filtered, regulated, lubricated air while the differential-pressure drain keeps the metal bowl clear of condensate.
Size 600 with a 3/4 in PT port is the top step of the G-series ladder - choose it when your line's flow demand sits above what a 400-size unit serves, and step down to 200/300/400 if your port and flow are smaller. This configuration is the low-pressure type (code L), so confirm the operating band suits your circuit; the exact regulation range for this variant is not published and we will confirm it on request. The drain is differential-pressure (the default), which bleeds the bowl automatically as pressure drops - pick automatic (A) or manual (M) variants if your maintenance routine prefers them. The 40 um standard filter grade is right for general plant air; choose the 5 um W-grade variant where downstream valves and cylinders need finer protection. The square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and the mounting bracket is included.
Because flow is published as curves rather than a single rated figure, 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-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so we do not quote a figure here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks the low-pressure regulator variant, suited to circuits that run below standard plant pressure; its exact regulation range is not published, and we will confirm it on request. The K code means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply fails. This unit also carries a square gauge reading in psi, a differential-pressure drain, and a 40 um filter element as standard.
