The AirTAC GFR600C20LC1TK AirTAC Filter Regulator NPT3/4 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 GFR600C20LC1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This size 600 unit has 3/4 in NPT ports, a 40 um filter element, a differential-pressure drain and an aluminium alloy bowl. It is the low-pressure (L) type, fitted with an external round gauge reading in MPa and a reverse (check) valve, and a mounting bracket is included.
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 (W) element, square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

Placed ahead of the clamping cylinders on a furniture press, it strips water and particulate from shop air and gives the operator a local, gauge-visible pressure setting point for the low-pressure clamp circuit.
Mounted at the 3/4 in drop feeding a valve island on a cartoning line, it cleans the supply and provides one filtered, regulated take-off point for the machine's low-pressure actuator group.
On a textile finishing line, the unit conditions the air feeding guide and tensioning cylinders, with the fitted check valve closing the line against backflow when the upstream supply dips.
Size and port set the flow path: the 600 body with 3/4 in NPT ports is the largest step in the GFR range (sizes 200-600, ports 1/8 to 1 in), so match the step to the air demand of the circuit. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The drain on this unit is differential-pressure, with automatic (A) and manual (M) available; the element is 40 um standard with a 5 um (W) option. Gauges come as the embedded square type or an external round gauge in MPa, psi or bar scales - this unit carries the round MPa gauge. Threads can be ordered in PT (standard), G (BSPP) or NPT. The L in the code marks the low-pressure regulator variant; its adjustment range is confirmed on request. A bracket is included.
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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and the full datasheet figures for this exact model on request.
The L in the code marks the low-pressure regulator variant; its exact adjustment range is not published in our transcribed material, so we confirm it on request. Everything else decodes normally: 3/4 in NPT ports, 40 um element, differential-pressure drain, round MPa gauge, check valve, bracket included, max inlet 1.0 MPa (145 psi) and -5 to 70 C operation.
