The AirTAC GFR600C20JF3WTK 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 GFR600C20JF3WTK is an AirTAC GFR filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure steady. This 600-size unit is threaded NPT3/4 (3/4 in), carries a 5 um filter element (the W grade, against the 40 um standard), drains condensate by differential pressure, and shows the set pressure on an embedded square gauge scaled in bar. A reverse/check valve is fitted and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the 600-size 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 to 1 in, and the catalogue options include 40 um or 5 um filtration, differential-pressure, automatic or manual drains, an embedded square gauge (external round gauge optional) with MPa, psi or bar scales, PT, G or NPT threads, a bracket or no bracket, and a reverse/check valve. Flow is published as curves rather than a single rated 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.

Feeding spray guns and air-driven agitators on a paint line: the 5 um element takes water and fine dirt out of the supply before the regulator holds a steady, gauge-monitored pressure to the booth.
Conditioning the air to the tool-clamp and chip-clearing circuits of a CNC machining centre, with the fitted check valve holding the downstream side if the main supply dips.
Point-of-use conditioning for analyser cabinets and pneumatic lab benches, where the 5 um grade and a stable, bar-gauge set pressure protect sensitive actuators and valves.
The real, decodable choices on this family: step the size (200/300/400/600) and port (1/8 to 1 in) against the air demand of your line; pick the drain - differential-pressure as fitted here, automatic, or manual (drain type also sets the regulation range: this differential-pressure unit regulates 0.15-0.9 MPa / 20-130 psi, while manual-drain units regulate 0.05-0.9 MPa / 7-130 psi); choose the filter grade, 40 um standard or 5 um (W) as on this unit; set the gauge scale to MPa, psi or bar; select the thread - PT is the standard, with G and NPT as catalogue options such as the NPT fitting on this model; decide bracket or no bracket; and add the reverse/check valve if the circuit needs it. Flow is published as curves, not a single rating, so send us your working pressure and 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 GFR600 as curves rather than a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
The differential-pressure drain is the default drain on the GFR family; automatic (code A) and manual (code M) drains are catalogue options on the same series. The drain type also sets the regulation range: differential-pressure and automatic units regulate 0.15-0.9 MPa (20-130 psi), while manual-drain units regulate 0.05-0.9 MPa (7-130 psi).
