The AirTAC GFR600C20JC3WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20JC3WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This configuration is a 3/4 in NPT-threaded unit with the finer 5 um filter element, a differential-pressure drain on the aluminium alloy bowl, a round pressure gauge reading in bar, and a built-in reverse/check valve that holds downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, in PT (standard), G (BSPP) and NPT threads, with 40 um or 5 um filtration, a choice of differential-pressure, automatic or manual drains, and embedded square or external round gauges in MPa, psi or bar scales. Flow for this size is published as curves rather than a single rated figure - ask us and we will confirm the datasheet figures 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 an automotive stamping line, this 3/4 in filter regulator conditions the air feeding pneumatic clamping fixtures: it strips water and swarf from the supply and holds the clamp pressure steady at the setpoint, with the check valve keeping clamps held if the main supply dips.
In a CNC machining cell, the unit sits ahead of the tool-changer and spindle air-purge circuit, giving the actuators clean, regulated air at a fixed pressure so tool swaps and purges stay consistent through the shift.
On a carton-forming and sealing line, this filter regulator supplies the sealing and pusher cylinders with air free of water and fine particles, protecting the valve seals while keeping cylinder pressure where the machine was set.
Size 600 with a 3/4 in port sits at the top of the GFR range; step between sizes 200/300/400/600 (ports 1/8 to 1 in) according to the air demand of your line, and we can check the published flow curves against your requirement before you order. The choices decoded into this code are: the 5 um element instead of the 40 um standard, the differential-pressure drain (automatic and manual are options), a round gauge with bar scale, the NPT thread (PT is the standard; G and NPT are order options), a reverse/check valve fitted, and no mounting bracket. Flow is published as curves, not a single rating, so please confirm sizing with us 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 rather than a single rated figure, so we do not quote a number on the page. Send us your operating pressure and air demand and we will confirm the datasheet flow curves for this exact model before you order.
The GFR series takes a 40 um element as standard and a 5 um element as the W option. The W in this code means it is fitted with the 5 um grade, the choice when downstream valves, cylinders or instruments are sensitive to finer particles. If your application only needs coarser protection, the 40 um standard element is available in the same size.
