The AirTAC GFR600C20ALF2K AirTAC Filter Regulator PT3/4, 3/4 in 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 GFR600C20ALF2K is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a PT3/4 (3/4 in) PT-thread port, a 40 um standard filtration element, and an automatic drain that expels collected condensate from the bowl without manual attention. It is the low-pressure regulator type, so it is intended for applications set below the standard adjustment band; the exact range for the low-pressure type is not published in the data we hold, so confirm it with us before ordering. A square pressure gauge reading in psi is fitted, a reverse (check) valve is included (code K), and the mounting bracket is supplied. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic, manual), a 5 um optional element (code W), gauge scale options, and G or NPT thread variants to order. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

On a CNC fixture line, air clamps often need to hold at a set pressure below the standard shop band. This low-pressure type filter regulator cleans the supply and lets the setter dial in the clamp pressure, with the psi gauge giving a direct reading at the machine.
Spray and coating booths run atomizing air at modest, closely held pressures. This unit filters carryover water and particles from the shop air and regulates the atomizing supply at low-pressure settings, while the automatic drain keeps condensate out of the bowl during long runs.
Conveyor diverters, pushers and gate cylinders on a packaging line need clean air at a steady, moderate pressure to stroke consistently. This 3/4 in filter regulator supplies that circuit, and the fitted check valve helps hold the circuit against backflow.
Start with the port and size: this unit steps up to PT3/4 on the size 600 body, the largest GFR frame, so match it to lines whose peak air demand sits above what 1/2 in and smaller units carry. Because flow is published as curves and not a single rating, send us your flow requirement and we will confirm the fit against the datasheet before you order. Choose the drain next: this unit has the automatic drain (code A), which suits unattended duty; manual and differential-pressure drains are available in the family if you prefer operator-controlled or pressure-differential purging. Filtration is the 40 um standard element; specify the 5 um W variant if downstream equipment needs finer particulate removal. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are order options. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and the 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 performance curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and required flow and we will confirm the sizing against the datasheet on request before you order.
The bowl collects water and dirt separated from the air. With the automatic drain, condensate is expelled from the bowl by itself as it accumulates, so no operator purging is needed. The family also offers a manual drain (code M) and a differential-pressure drain as the default, if your maintenance routine prefers those.
