The AirTAC AirTAC GFR60020JC2GK Filter Regulator G3/4, psi gauge is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20G is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This unit is built on the 600 size with a G3/4 port, a 40 um filter element, and a differential-pressure drain that discharges collected condensate automatically when the pressure drop across the element is sufficient. The 600 size uses an aluminium alloy bowl, and the fitted round gauge reads downstream pressure in psi. A reverse/check valve is fitted and the unit is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the standard regulator adjusts outlet pressure from 0.15 to 0.9 MPa (20 to 130 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of 40 um or 5 um (W) filtration, manual, automatic or differential-pressure drains, square or round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application before ordering.

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). Air must not freeze in the unit. 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, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Mounted on the 3/4 inch main feeding a machining cell, it filters water and chips-carried condensate out of the supply and holds a fixed set pressure to spindle clamps and pallet-locking cylinders.
Installed ahead of a bottling conveyor section, it conditions the air and regulates pressure to stopper cylinders, pusher diverters and gate actuators so they cycle at a consistent setting.
Used as a point-of-use filter regulator on 3/4 inch drop legs in an assembly plant, it delivers clean, pressure-set air to impact wrenches, air clamps and fixture-actuation circuits at each workstation.
Choose the size by port and flow demand: this 600 unit carries a G3/4 port, the largest step in the range, for lines that have outgrown 1/2 inch and below. The 40 um element is the standard grade; specify code W for 5 um where finer protection matters. Drain options are differential-pressure (this unit, no operator attention in normal service), automatic (A), or manual (M). The fitted round gauge reads in psi; the embedded square gauge and MPa or bar scales are catalogue options. Thread here is G (BSPP); PT is the AirTAC standard and NPT can be ordered as a specification choice. No mounting bracket is included with this code (J).
Flow for the GFR series is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm the correct size against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request.
This code has no drain letter, so it carries the differential-pressure drain, which discharges condensate automatically when the pressure drop across the element is sufficient. Catalogue alternatives are the automatic drain (code A) and the manual drain (code M), which you drain by hand.
