The AirTAC GFR600-20G AirTAC Filter Regulator G3/4 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" 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 GFR600-20G is a size-600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in one body. This configuration has a G3/4 (BSPP) port, a 5 um filter element (code W, finer than the 40 um standard), a differential-pressure drain that bleeds condensate whenever the pressure drop across the element rises, a round external gauge reading in psi, and a standard (not low-pressure) regulator. The aluminium alloy bowl is specific to the 600 size, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of drain type, filter grade, gauge style and scale, thread form (PT standard, G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

Conditioning and pressure-setting the air feeding spray guns and booth actuators, where the 5 um element helps keep water and carryover out of the finish and the psi gauge lets the line setter dial in the gun supply pressure.
A single body filtering and regulating the supply to pneumatic stopper, pusher and clamp cylinders along a bottling or packaging conveyor, with the differential-pressure drain keeping condensate moving out of the bowl during long runs.
Point-of-use conditioning ahead of workholding clamps and tool-change actuators on a machining centre, where a stable, filtered 3/4 in supply branch feeds several clamping circuits.
Size and port step up together: 200, 300, 400 and 600 cover 1/8 to 1 inch ports, so pick the size whose flow curve covers your demand at an acceptable pressure drop - we can check the curve against your consumption. Drain choice is differential-pressure (this unit, default), automatic (code A) or manual (code M); filter grade is 40 um standard or 5 um (code W, as fitted here). Gauges are offered embedded square or external round, with MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G and NPT available to order; this unit is G-threaded. Brackets are optional (this unit ships without one, code J).
Because flow is published as curves and not a single rating, please ask us to confirm sizing against your 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 flow for the GFR series as curves, not as a single rated number, so there is no one figure we can quote. Send us your line pressure, downstream demand and allowable pressure drop and we will confirm the sizing from the datasheet curves on request before you order.
The W code in GFR600-20JC2WG selects the 5 um element, one grade finer than the 40 um standard, for applications that need cleaner air. Drainage here is differential-pressure: condensate is discharged automatically whenever the pressure drop across the element builds up, with no operator action needed. Manual (M) and automatic (A) drain versions are available in the same size.
