The AirTAC GFR60025LJC1T AirTAC Filter Regulator NPT1 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 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 GFR60025LJC1T is a 600-size filter regulator: it removes water and particulate from compressed air and sets a stable downstream pressure in one body. This configuration is built for 1 in NPT ports, carries the standard 40 um filtration grade, and uses a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. Because it is the low-pressure (L) type, it is intended for circuits where the working pressure is set well below standard plant levels. The bowl on this size is aluminium alloy, and the unit is fitted with an external round pressure gauge reading in MPa; no mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um (W) element option, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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.

| (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. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. 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. |

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.

Mounted at the air inlet of a cartoning or wrapping line, this unit filters water and scale out of the plant supply and holds a reduced, steady pressure to the machine's cylinders and directional valves, protecting the sequence from supply fluctuation.
Installed at the point of use on a factory ring main, it conditions the air feeding hand tools, clamps and workholding fixtures in an assembly cell, with the MPa round gauge giving the operator a direct reading of the set working pressure.
Fitted ahead of the air cylinders that raise stops, divert product and tension belts on a conveyor system, it keeps moisture and particulate out of the actuators while holding the low set pressure those stations are designed around.
Start with the port step: this model is the 600 size with a 1 in NPT thread, the largest port in the family, so match it to your main air drop rather than a branch line. Choose the drain to suit access: differential-pressure (this unit) needs no attention at normal duty, automatic drains continuously, and manual suits supervised installations. If finer filtration is needed, the 5 um (W) element is the alternative to the 40 um standard fitted here. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are decodable options, and the J in this code means you should plan your own bracket or panel fixing. The L code marks this as the low-pressure type, so specify it only where your setpoint sits below standard regulator range. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 performance curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your line pressure, set pressure and required air consumption, and we will confirm the correct size against the datasheet curves on request before you order.
The L code marks this as the low-pressure type of the GFR filter regulator, intended for circuits where the downstream pressure is set well below the standard type's range; the exact low-pressure regulation range is not published in the catalogue, so confirm it with us for your setpoint. Everything else decodes as standard: 600 size, 1 in NPT port, 40 um element, differential-pressure drain, aluminium bowl, round MPa gauge, no bracket and no reverse valve.
