The AirTAC GFR60020MJF1WTK AirTAC Filter Regulator NPT 3/4 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is built around 3/4 in NPT ports for larger supply lines, a fine 5 um filter element (code W), a manual drain for scheduled bowl emptying, an embedded square gauge scaled in MPa, and a built-in reverse (check) valve that holds downstream pressure if the upstream supply is lost. The bowl on this size is aluminium alloy, and the J code means it ships without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of 40 um standard or 5 um fine filtration, manual, automatic or differential-pressure drains, gauge and thread options, and a maximum inlet pressure of 1.0 MPa (145 psi). Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures for your application on request.

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 0.05 - 0.9 MPa (7 - 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 on the 3/4 in main drop feeding a CNC machining cell, it strips water and fine particles from the plant air and holds a steady regulated pressure to machine spindles, clamps and tool changers, with the check valve holding settings through supply dips.
Mounted at the feed to a cartoning or case-packing conveyor line, it conditions the air driving cylinders, grippers and diverters, keeping pressure stable so pick-and-place and sealing motions stay consistent through the shift.
Fitted at department-level air drops in a factory, it gives each area its own filtered, regulated supply off the main header, protecting downstream valves and actuators from scale, condensate and pressure swings in the ring main.
Start with the port and size: this unit is the 600 frame with 3/4 in NPT threads, the largest step in the GFR range, so match it against the pipe size and air demand of the line it feeds. The 5 um element (W code) suits applications needing finer particulate removal than the standard 40 um grade; if your use tolerates coarser filtration, the standard grade is the default. The manual drain means an operator opens the bowl drain during maintenance rounds - if nobody will do that reliably, consider the automatic or differential-pressure drain variants instead. The fitted square gauge reads in MPa; psi and bar scales and an external round gauge are available as options. NPT is the thread on this code; PT (standard) and G (BSPP) versions exist in the catalogue. No mounting bracket is included with the J code. Because flow is published as curves rather than one rated figure, 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and air demand and we will confirm the flow and sizing from the datasheet on request before you order.
The M code specifies a manual drain: condensate collected in the aluminium bowl is released by opening the drain during maintenance checks. With a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi). If the installation will not receive regular checks, the automatic or differential-pressure drain variants are the better choice.
