The AirTAC GFR600-20C2WT AirTAC Filter Regulator NPT3/4 5um 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 GFR600-20C2WT is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 600-size unit is fitted with 3/4 in NPT ports, 5 um filtration (the finer W grade, versus the standard 40 um element), a differential-pressure drain that bleeds condensate automatically as flow passes through, a round external gauge reading in psi, and a mounting bracket. The aluminium alloy bowl on this size suits duty where a polycarbonate bowl is not preferred. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part, sold by a distributor for the US market. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT to order), and bracket. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application before you order.

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. |

| 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. |
| T | NPT 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.

Drops in on a 3/4 in branch off the plant air ring main, cleaning the supply and holding a steady regulated pressure to a production cell's distribution manifold.
Feeds filtered, regulated air to the tool-change and clamping circuits of a machining centre, where the 5 um element helps protect sensitive pneumatic valves from particulate carryover.
Conditions the air feeding conveyor stopper and gating cylinders on a packaging line, with the regulator keeping actuator speed consistent as upstream pressure drifts.
Size and port set the capacity: 600 is the largest GFR size, with 3/4 in NPT ports here, so step up or down (200/300/400/600) to match the air demand of the line. Filtration grade is a real choice: 40 um is the standard element, while this unit carries the 5 um W grade for finer protection of downstream tools and components. Drain type matters: differential-pressure (fitted here) drains with flow, automatic drains on a timer-free basis, and manual requires an operator. Gauge style and scale are selectable - embedded square or external round, in MPa, psi or bar (this unit: round, psi). Thread is PT as standard with G and NPT as order options; a bracket is included unless the J code is specified. Flow is published as curves, not a single rating, so send us your air demand and we will confirm sizing against the datasheet 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, not as a single rated figure, so we do not quote a number here. Send us your application's air demand and working pressure and we will confirm the datasheet flow curve and correct sizing for you before you order.
The W code in the model means the finer 5 um filtration grade instead of the standard 40 um element, useful when downstream valves and instruments need cleaner air. The blank drain position means the differential-pressure drain: condensate is expelled automatically as air flows through, with no manual draining routine. Manual (M) and automatic (A) drains are available as alternative order codes.
