The AirTAC GFR60025ALF1T AirTAC Filter Regulator NPT1 1 in 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 GFR60025ALF1T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 in NPT port, a 40 um standard filtration element, an automatic drain that ejects collected condensate without manual attention, and a low-pressure regulator type for circuits that run at reduced pressure. The embedded square gauge reads outlet pressure in MPa, and the aluminium alloy bowl suits this large frame size.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread choices of PT (standard), G and NPT, drain types, 40 um or 5 um filtration, gauge scale options and low-pressure variants. Flow is published as curves rather than a single rating, so we 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. 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure 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. |
| (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.

Feeds cleaned, pressure-controlled air to a packaging machine's actuated carton sealers and diverters, with automatic drain keeping condensate out of the valves during continuous shifts.
Supplies a workholding clamp circuit on a machining centre that runs at reduced pressure, letting the setter read and adjust the clamping force on the built-in square MPa gauge.
Conditions and regulates the air feeding gate cylinders and product stoppers along a bottling conveyor, with the 1 in NPT port matching the main drop leg serving the line.
Step up or down through the GFR sizes (200/300/400/600) and port codes (1/8 in to 1 in) to match the pipe size and air demand of the circuit; the 600 frame with a 1 in port is the largest step in the family. Choose the drain to suit access: automatic (this model) for unattended duty, manual for supervised points, or differential-pressure as the default. Filtration is 40 um standard; specify code W for 5 um where finer protection is needed. The square MPa gauge is fitted here; an external round gauge in MPa, psi or bar scale is optional. Thread is NPT on this unit, with PT (standard) and G available to order; a mounting bracket is included.
Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. The exact regulation range of the low-pressure type is also confirmed from the datasheet on request.
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 number, so we do not quote a figure here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The A in the code specifies an automatic drain: condensate collected in the aluminium bowl is ejected without anyone opening a valve, which suits unattended or high-duty installations. The L specifies the low-pressure regulator type, intended for circuits that run at reduced outlet pressure; its exact adjustment range is confirmed from the datasheet on request.
