The AirTAC GFR600-25T AirTAC Filter Regulator 1 in NPT, Low-Pressure 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 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 GFR600-25T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is tapped 1 in NPT, carries a manual drain on the aluminium alloy bowl, uses the standard 40 um filter element, and is a low-pressure regulator fitted with an embedded square gauge scaled in bar. No mounting bracket is included and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G (BSPP) or NPT to order, with manual, automatic or differential-pressure drains, 40 um or 5 um (W) elements, gauge or no-gauge variants, and standard or low-pressure regulation. Flow is published as curves rather than a single rating, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure 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. |
| 3 | Gauge scale: bar. 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. |
| (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.

Point-of-use filtration and pressure regulation ahead of spray guns and air lines in a paint booth, where water and dirt must be stripped from the shop air and the supply held at a lower regulated setting.
Feeding clean, regulated air to the cylinders and grippers of a carton erector-sealer, with the manual drain emptied during scheduled changeovers and the square bar gauge giving operators a visible line-pressure check.
Mounted at the air inlet of a skid-built control panel, conditioning and regulating the supply to pilot valves and small actuators, with the 1 in NPT connection matching the skid's main air header.
Size 600 with a 1 in NPT port is the largest step in the GFR range; step down to 200/300/400 if your line needs less flow - we can check the published flow curves against your demand before you order. The drain here is manual, so an operator drains the bowl; automatic (A) or the default differential-pressure drain are available if you prefer unattended drainage. The 40 um element is standard; specify W for the 5 um grade. The embedded square gauge is scaled in bar; an external round gauge with MPa, psi or bar scale is optional, as is a no-gauge version (N). Thread is NPT on this unit; PT is the standard and G (BSPP) is an order option. A mounting bracket can be added (the J code omits it). This is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us if your set pressure is critical.
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.
Flow for the GFR600 is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow data against your required flow before you order.
This unit carries code M, a manual drain: open the drain at the bottom of the aluminium alloy bowl to discharge collected water as part of your routine checks. If you want unattended drainage, the same model is available with an automatic drain (A) or the default differential-pressure drain - tell us and we will quote the variant.
