The AirTAC GFR600C20ALF2WT AirTAC Filter Regulator NPT3/4, 5 um 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 AirTAC GFR600C20ALF2WT is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure. This size 600 unit carries a 3/4 in NPT port, a 5 um filter element (code W), an automatic drain that ejects collected condensate without manual attention, and the low-pressure regulator type for circuits that sit below the standard range. The embedded square gauge reading in psi is fitted, the metal bowl is aluminium alloy at this size, a mounting bracket is included, and the maximum inlet pressure is 1.0 MPa (145 psi) with a working temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices of differential-pressure, automatic or manual, 40 um standard or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application - we will send the datasheet 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.

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 supply air to the cylinder circuit of a small pneumatic stamping press, with the 5 um element keeping particulate away from valve seats and seals.
Holding a gentle setpoint on a low-pressure air circuit, such as a clamping or web-tension line, where the low-pressure regulator type is the right match for the job.
Supplying clean, regulated air to the cylinders and grippers on a carton-forming conveyor, with the automatic drain clearing condensate through long production runs.
Step through the GFR sizes (200 / 300 / 400 / 600) to match the port and flow your line needs; this unit is the 600 frame with a 3/4 in NPT thread (PT is the standard thread, G and NPT are catalogue options to order). Choose the drain: differential-pressure as the default, automatic (as fitted here) for unattended condensate removal, or manual where you want positive control. Pick 40 um standard or 5 um (W) filtration, and the gauge scale - this one reads psi on the embedded square gauge, with an external round gauge optional. A bracket is included unless the J (no bracket) variant is ordered. Flow is published as curves, not a single rating, so let us confirm sizing against your application 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and required flow and we will confirm sizing from the datasheet on request.
L marks the low-pressure regulator type. The exact regulation range for this variant is not published in the standard tables, so ask us to confirm it against your setpoint before ordering. The rest of the code decodes as: size 600, 3/4 in NPT port, automatic drain, 5 um element, and a square gauge reading in psi.
