The AirTAC GFR600C20ALC2 AirTAC Filter Regulator PT3/4 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 GFR600C20ALC2 is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit is a 3/4 in PT-threaded low-pressure type with an automatic drain, a 40 um filter element, an aluminium alloy bowl, a round psi gauge fitted, and the mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, plus options for manual or differential-pressure drains, a 5 um element, G or NPT threads, alternative gauge scales, and a reverse/check valve. Flow and other datasheet figures are published as curves; we confirm them 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. 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.

| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |

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.

Filtered, regulated air at low pressure for clamp and hold-down cylinders on carton and shrink-wrap lines.
Drops water and 40 um particulate from the shop air feeding paint guns and air-assisted applicators on a finishing line.
Conditions and regulates the 3/4 in air main serving loom jets and pneumatic thread handlers in a weaving shed.
Size 600 with a 3/4 in port suits installations plumbed at 3/4 in; step down to 200, 300 or 400 for smaller ports. The automatic drain ejects collected condensate without daily manual attention; manual and differential-pressure drains are the alternatives in the range. The 40 um element is the standard grade - specify the W option for 5 um where finer filtration is needed. This unit is the low-pressure (L) regulator type; its exact set range is not published, so confirm it against your application with us. The fitted round gauge reads in psi; square gauges and MPa or bar scales are available. PT thread is standard and G or NPT are order options, and the mounting bracket is included. Flow is published as curves rather than a single rating, so ask us to confirm sizing against the application before ordering.
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 filter-regulator flow as curves rather than a single rated figure, so we do not quote a number. Send us your flow and pressure requirements and we will confirm the sizing from the datasheet on request.
GFR is the filter-regulator family, 600 is the size, 20 is the 3/4 in port, A is the automatic drain, L is the low-pressure regulator type, and C2 is the round gauge with psi scale. The thread is PT as standard; G and NPT are order options.
