The AirTAC GC60020MLF2K AirTAC F.R.L. Unit 3/4 in PT, 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 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC60020MLF2K is a three-piece AirTAC F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one GC600 unit. This configuration is built around a 3/4 in PT port and carries the full function set - water and particulate filtration at the standard 40 um grade, pressure regulation in the low-pressure type, and oil-mist lubrication for downstream air tools and cylinders. The filter bowl is drained manually, the regulator is fitted with an embedded square gauge scaled in psi, and a reverse/check valve (code K) is fitted. At size 600 the filter bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi), with an operating temperature range of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC combination family spans sizes 200, 300, 400 and 600, with a choice of port sizes, PT / G / NPT threads, manual, automatic or differential-pressure drains, a 40 um standard or 5 um (W) filter grade, square or round gauges in MPa, psi or bar scales, and a reverse/check valve option. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

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.

A three-unit F.R.L. at the plant-air drop feeding a stamping press: filtered, regulated low-pressure air and oil mist to the press clutch, counterbalance and control circuits, with the check valve holding the set circuit against backflow.
Mounted at the header serving a bottling-line conveyor, this combination conditions the air that drives stopper gates, pushers and lift cylinders - 40 um filtration, low-pressure regulation and lubrication in one 3/4 in assembly.
Installed on the air-preparation panel of a weaving or spinning machine, the GC60020MLF2K delivers cleaned, pressure-controlled and lubricated air to the machine's jetting and actuation circuits from a 3/4 in PT supply.
Start with size and port: the 600 size with its 3/4 in PT port is the largest step in the GC range, so match it against the air demand of the machine or line it will feed - and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The regulator in this unit is the low-pressure type; its exact adjustment range is not published in our data, so confirm it with us if your set pressure is critical. Other decodable choices: manual drain (as here) versus automatic or differential-pressure drain; 40 um standard filtration versus the 5 um (W) option; square versus round gauge with MPa, psi or bar scales (this unit is psi); PT as the standard thread with G and NPT as order options; and the reverse/check valve, which is fitted on this code. A mounting bracket is included.
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 rated flow, Cv or SCFM number. Tell us your application and operating pressure and we will confirm the datasheet and flow figures for this exact unit on request before you order.
The M in the code specifies a manual drain on the filter bowl, so condensate is released by hand rather than automatically - choose the automatic (A) or differential-pressure option if the unit is hard to reach. F2 specifies the embedded square gauge scaled in psi; MPa and bar scales and an external round gauge are available as options. The K in the code means a reverse/check valve is fitted.
