The AirTAC AirTAC GFR60020AF1WT 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 automatic 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 GFR60020AF1WT is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This size-600 unit is supplied with a 3/4 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 5 um filter element for finer filtration than the standard 40 um grade, an embedded square gauge scaled in MPa, and an aluminium alloy bowl. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and it operates from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G or NPT as order options, a choice of automatic, manual or differential-pressure drains, and 40 um or 5 um elements. Flow is published as curves rather than a single rated figure, so ask us to 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic 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. |
| (blank) | Mounting bracket included. |
| (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. |
| (blank) | No reverse-flow valve (the default). |
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.

Mounted on a 3/4 in main drop, it dries and filters shop air and holds a steady regulated supply to pneumatic impact wrenches and clamping fixtures along the cell.
Placed ahead of a pneumatic valve actuator on a plant skid, it strips water and fine particles from the supply line and keeps the actuator's set pressure stable through the shift.
Feeding the cylinders and grippers of a carton-sealing conveyor, it removes condensate carried in from the compressor room and holds the working pressure the machine was set up for.
The real choices in this range are decodable from the code. Step through sizes 200 / 300 / 400 / 600 to match the port and the flow your line needs - this unit is the 600 size with a 3/4 in NPT port. Choose the drain: automatic (fitted here) for unattended condensate removal, manual where you prefer a scheduled blow-down, or differential-pressure. Choose the element: 40 um standard or 5 um (code W) for finer protection - this unit carries the 5 um grade. Gauges are embedded square with MPa, psi or bar scales, and an external round gauge is optional; thread is PT standard with G and NPT as order options; a mounting bracket is included. Flow is published as curves, not a single rating, so 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. 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 one number here. Tell us your application and required flow, and we will confirm the datasheet figures for this 3/4 in, size-600 unit before you order.
This configuration carries code A, the automatic drain, which ejects collected condensate from the aluminium alloy bowl without anyone opening it - useful for unattended installations. The same GFR600 size is also available with a manual drain for scheduled blow-down, or with the differential-pressure drain as the default; the drain choice is part of the model code.
