The AirTAC GFR60020JF2WTK AirTAC Filter Regulator NPT3/4 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 GFR60020JF2WTK is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, an embedded square pressure gauge reading in psi, and a reverse/check valve that holds downstream pressure if the upstream supply is lost. Ports are 3/4 in NPT thread, and the maximum working (inlet) pressure is 1.0 MPa (145 psi). The standard regulator adjustment range for this drain type is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the drain bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, PT, G or NPT thread, and gauge or no-gauge variants. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

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.

Installed where the 3/4 in main drops air to a packaging machine's valve island: the 5 um element protects directional valves from water and fine debris, the regulator sets a stable working pressure, and the check valve holds the circuit if the main supply dips.
Feeding clamps and a pneumatic press cell, where the regulator sets the clamping pressure from the psi gauge and the 5 um grade keeps moisture and particles out of the clamp cylinders' seals over long production runs.
Mounted at the drop feeding conveyor diverters and cleaning-blow nozzles: the filter stage strips condensate before it reaches the diverters, the regulator tunes blow-off pressure to the job, and the differential-pressure drain copes with continuous line duty.
Size 600 with 3/4 in NPT ports is the largest step in the GFR range, so start there when the line's required flow is high; step down to 300 or 400 if the curve for your flow shows a smaller body is adequate. This unit carries the 5 um (W) element - choose it when downstream valves, cylinders or instruments need finer filtration than the 40 um standard; the drain here is differential-pressure, which suits a steady-duty line, while automatic or manual drain variants exist for intermittent or attended duty. The square gauge is fitted and reads in psi (MPa and bar scales are also available), and the K code means a reverse/check valve is fitted to hold downstream pressure. Thread is NPT here; PT is the catalogue standard and G is also orderable. No mounting bracket is included with the J code. Because flow is published as curves rather than a single rating, 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. The reflux valve permits reverse flow 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. Tell us your inlet pressure, set pressure and required flow, and we will confirm the correct size from the datasheet curves on request before you order.
The W in the code selects the 5 um filter grade instead of the 40 um standard, giving finer protection for downstream valves and cylinders. The K in the code means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is interrupted. Both are catalogue options you can order with or without on other GFR600 units.
