The AirTAC GC60020MLF2 AirTAC F.R.L. Unit, PT3/4, Square psi Gauge 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 GC60020MLF2 is an AirTAC GC600 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack. This configuration carries PT3/4 ports, a 40 um standard filter element, a manual drain on the filter bowl, and a low-pressure type regulator fitted with an embedded square gauge scaled in psi. Because this is the 600 size, the filter and lubricator bowls are aluminium alloy, suited to heavier plant-air duty. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC combination family is available in sizes 200, 300, 400 and 600, with port options from PT1/8 up to PT1, G (BSPP) and NPT threads to order, manual, automatic or differential-pressure drains, a 5 um filter element option, gauge scale choices and a reverse/check valve option. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

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 from a factory air receiver, the GC60020MLF2 filters water and particulate from the main line, holds a stable regulated pressure for downstream users, and meters oil mist into the distribution network feeding air tools and actuators across the shop floor.
Mounted on the air-preparation drop feeding a packaging or bottling line's cylinders and grippers, this three-unit set cleans the supply, keeps the regulator set point steady so pick-and-place strokes stay consistent, and lubricates the cylinders and valves on the line.
Fitted at a 3/4-inch air drop serving impact wrenches, grinders and air motors in a machine or fabrication shop, the combination removes condensate and swarf-laden particulate, regulates pressure for the tool circuit, and delivers oil mist to keep air tools running smoothly.
Step up through the GC sizes (200, 300, 400, 600) to match the port and the flow your line needs; this unit is the 600 size with PT3/4 ports. Drain type is a real choice: manual drain means an operator drains the filter bowl on a schedule, while automatic and differential-pressure drains discharge condensate without intervention. The 40 um element is the standard grade; specify the W code for the 5 um option where finer particulate capture matters. Gauge scale is selectable (MPa, psi or bar) - this unit carries the square gauge in psi. Thread is PT as standard, with G (BSPP) and NPT available as order options. Note that the regulator in this unit is the low-pressure type, so confirm the exact adjustment range against your set pressure before ordering. Flow is published as curves, not a single rating, so ask us to confirm sizing against the application 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 curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and line pressure and we will confirm the flow and sizing from the datasheet on request before you order.
The M in GC60020MLF2 specifies a manual drain on the filter bowl: an operator opens the drain to discharge collected condensate on a schedule. If you prefer unattended condensate removal, the GC600 is also available with an automatic drain (code A) or a differential-pressure drain (blank code) - ask us to quote the variant you need.
