The AirTAC GFR60020AF1WTK 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 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 GFR60020AF1WTK is a filter regulator: in one body it removes water and particulate from compressed air and holds downstream pressure steady. This is the largest GFR frame (size 600) with a 3/4 in NPT port, an automatic drain that purges collected condensate without manual attention, a 5 um filter element for finer filtration than the 40 um standard, an embedded square gauge scaled in MPa, and a reverse (check) valve fitted. The bowl on this size is aluminium alloy, a mounting bracket is included, maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 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 line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, plus a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge or no-gauge variants. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and full datasheet details 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.

| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| 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. |

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-assisted applicators on a paint line, where the 5 um element and steady regulated pressure help keep finish quality consistent and the automatic drain handles condensate without a technician visiting each station.
Supplying cylinders and vacuum generators on a carton-forming and case-sealing conveyor, where the 3/4 in NPT port serves a main drop and the check valve helps hold the circuit if upstream supply dips.
Regulating air to workholding clamps and tool-change actuators on a machining centre, where the square MPa gauge gives the operator a direct read of clamp pressure and the automatic drain keeps moisture out of the valve stack.
Size and port set the capacity: this unit is the 600 frame with a 3/4 in NPT port, the largest step in the range - step down through 200/300/400 (ports 1/8 to 1/2 in) if your flow demand is smaller. Drain type is a real choice: this code carries the automatic drain, which suits unattended installations; manual and differential-pressure drains are the alternatives. Filter grade: the W code selects the 5 um element; the 40 um standard element is the option where finer filtration is not required. The embedded square gauge on this unit is scaled in MPa, with psi or bar scales and an external round gauge available as options. Thread: NPT as coded here; PT is the catalogue standard and G (BSPP) can be ordered. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as performance curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and the flow your equipment needs, and we will confirm sizing against the datasheet curves before you order.
The W code selects the 5 um element, one step finer than the 40 um standard, which suits downstream valves, cylinders and instruments that tolerate less particulate. The A code adds the automatic drain, which purges collected condensate on its own instead of relying on scheduled manual draining - useful on runs that operate unattended.
