The AirTAC GFR60025AJF2TK AirTAC Filter Regulator 1 in NPT is a genuine G-series filter regulator: water separation, 40 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 GFR60025AJF2TK 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 a 1 in NPT ported unit with an automatic drain that discharges collected condensate without manual attention, a 40 um standard filtration element, a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost, and an embedded square gauge reading in psi. The pressure setting is adjusted across 0.15-0.9 MPa (20-130 psi), and the maximum working (inlet) pressure is 1.0 MPa (145 psi). 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 family is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of PT (standard), G or NPT thread, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) element, square or external round gauges with MPa, psi or bar scales, and optional brackets. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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 0.15 - 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.

|---|---|
| 25 | Port size PT1". 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)). |

| J | Supplied without bracket. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Feeds a spray-booth air drop where water and pipe scale must be stripped from the supply and the atomizing pressure held steady at the gun station, with the automatic drain clearing condensate between shifts without an operator visit.
Conditions and regulates the air feeding carton-forming and case-sealing cylinders on a packaging conveyor, keeping set pressure stable through the shift while the check valve holds the circuit if the main supply is interrupted.
Installed at the 1 in main air inlet of a machining cell to filter plant air before it splits to spindle purge, tool-change and clamping circuits, with the psi gauge giving operators a local pressure reference at the machine.
Step up or down through the 200/300/400/600 size ladder to match the port and the flow your line needs; this unit is the 600 size with a 1 in NPT port, the largest step in the family. Choose the drain to suit access: automatic (this unit, code A) for unattended condensate discharge, manual where you want positive control, or the differential-pressure default. The 40 um element on this unit suits general plant air; specify the W code for the 5 um element where finer filtration is wanted. The square gauge here reads in psi; MPa and bar scales are also available, and an external round gauge is an option. Thread is NPT on this unit; PT is the catalogue standard and G is also orderable. Note the J code means no mounting bracket is supplied - order one separately if you bracket-mount. 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 on the page. Tell us your application and we will confirm the datasheet flow figures for this 600-size, 1 in NPT unit on request before you order.
The A code means the drain bowl discharges collected condensate automatically, so no manual draining is needed where access is difficult. The K code means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply drops. Both are factory-fitted in this configuration.
