The AirTAC GFR60025LC1WTK AirTAC Filter Regulator NPT1 Low-Pressure 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 differential-pressure 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 GFR60025LC1WTK is a filter regulator: water and particulate removal plus downstream pressure regulation in a single 600-size body with a 1 in NPT port. This configuration is the low-pressure type (code L), fitted with a 5 um filter element (code W), a differential-pressure drain, a built-in reverse/check valve (code K) and an external round pressure gauge reading in MPa (code C1). The bowl on this 600 size is aluminium alloy, and a mounting bracket is included.
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 is offered with 40 um or 5 um elements, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure 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). |
| C | Gauge shape: Round. 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 on a low-pressure compressed-air header in a plant, where filtered, regulated air at a modest setting feeds a whole section of the shop rather than a single valve.
Conditioning the air feeding pneumatic diverters, stops and gate cylinders along a packaging or bottling conveyor, with the check valve holding the downstream circuit if upstream pressure dips.
Supplying a bank of air-operated valves or diaphragm-actuated control valves that need clean, moisture-reduced air held at a low, stable setpoint.
Choose the size and port step against the air demand of the circuit: this unit is the largest GFR step, size 600 with a 1 in port, intended for high-demand mains. This code already fixes the real choices: 5 um filtration instead of the 40 um standard, a differential-pressure drain, the low-pressure regulator type, a round MPa gauge, a fitted check valve, NPT thread and an included bracket. If you need a different drain, gauge scale, thread (PT or G) or the standard regulator type, those are orderable variants in the same family.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated number, and the exact regulation range of the low-pressure type is not in the published summary. Send us your line pressure, required downstream setting and air consumption and we will confirm suitability against the datasheet before you order.
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 family as performance curves, not as a single rated figure, so we do not quote a number here. Tell us your inlet pressure, required downstream setting and air consumption, and we will confirm the flow and sizing against the datasheet on request.
Code L selects the low-pressure regulator variant of the GFR family instead of the standard type; its exact adjustment range is not in the published summary, so we confirm it on request. Code C1 adds the optional external round gauge reading in MPa (psi and bar scales are also available), alongside the 5 um element, differential-pressure drain, fitted check valve and included bracket that this code carries.
