The AirTAC GFR60025ANWTK AirTAC Filter Regulator NPT1 5 um Auto Drain 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 PT1" 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 GFR60025ANWTK is a 600-size filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded NPT1 (1 in), carries a 5 um filter element (code W), and drains condensate automatically, so the bowl empties itself during operation without manual attention. The standard regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi), and a reverse (check) valve is fitted. No gauge is supplied with this code. At size 600 the bowl is aluminium alloy, and the unit works in a -5 to 70 C (non-freezing) environment.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with manual or differential-pressure draining, a 40 um standard element instead of 5 um, an embedded square gauge or external round gauge, and G (BSPP), NPT or PT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

| 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. |

| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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. |

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.

Point-of-use conditioning ahead of spray guns and air-assisted applicators, where the 5 um element and steady regulated pressure support consistent finish work on the line.
Filtered, regulated supply to pneumatic clamps and tool-change actuators on a machining centre, with the check valve helping hold the downstream circuit's set pressure.
Conditioning the 1 in main feeding diverters, pushers and stopper cylinders on a bottling or carton-packing conveyor, with automatic draining suiting multi-shift running.
Size and port are the first choice: 600 is the largest GFR frame, here with a 1 in NPT port, and the frame should be stepped up or down against the flow your line actually needs. Drain type is a real decision: automatic draining (this code) suits unattended duty, while manual and differential-pressure draining are the other catalogue options. Filter grade is 5 um on this unit; the standard grade is 40 um if finer filtration is not required. A gauge is not fitted on this code, but embedded square or external round gauges with MPa, psi or bar scales can be ordered. Threads come as PT (standard), G (BSPP) or NPT, and 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 flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the relevant flow and datasheet figures on request before you order.
The A code means condensate is discharged from the bowl automatically during operation, so the unit does not depend on someone opening a manual drain. Manual and differential-pressure draining remain available as catalogue options if you prefer a different arrangement.
