The AirTAC GFR600C20LC2 AirTAC Filter Regulator 3/4 in PT Low-Pressure 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 See datasheet 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 GFR600C20LC2 is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This 600-size unit is built with a 3/4 in PT port, the standard 40 um filter element and a differential-pressure drain, and its regulator is the low-pressure type for circuits set below the standard range. A round pressure gauge scaled in psi is fitted for a direct local readout, the aluminium alloy bowl suits the largest frame size, and a mounting bracket is included. No reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or manual drains, a 5 um element (code W), square or round gauges scaled in MPa, psi or bar, G (BSPP) or NPT threads, and a no-bracket variant. Flow is published as curves rather than a single rating, 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. 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.

Filter and regulate the air feed to spray guns and air-driven agitators in a finishing booth where coatings call for low set pressures; the 40 um element keeps water and debris away from the fluid tip.
Point-of-use conditioning at a 3/4 in machine drop on a packaging line: the bowl strips condensate and the low-pressure regulator holds a gentle, stable setting for delicate actuators and hold-downs.
Condition instrument air on a pilot-plant skid where clean, dry air and low set pressures protect sensitive pneumatic controls, with the psi gauge giving operators a direct local readout.
Size and port set the air capacity: 600 is the largest GFR size, here with a 3/4 in PT port, so step up or down through 200/300/400/600 against the air your line needs. Choose the drain: differential-pressure (this model), automatic (code A) or manual (code M). Filter grade is 40 um standard; specify W for the 5 um element where finer filtration matters. Gauges are an embedded square gauge or an optional external round gauge, scaled in MPa, psi or bar - this unit carries a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options, and code J deletes the bracket. Because flow is published as curves rather than a single rating, send us your application and we will confirm sizing before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your inlet pressure, set pressure and expected air demand and we will confirm the flow from the datasheet on request.
It marks the low-pressure regulator type, intended for settings below the standard range. The exact setting range for this low-pressure version is not published in the catalogue, so we confirm it on request. The rest of the code decodes as: 600 size, 3/4 in PT port, differential-pressure drain, 40 um element, round psi gauge, bracket included.
