The AirTAC GFR60025LJC3TK 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 GFR60025LJC3TK is an AirTAC GFR600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has 1 in NPT ports, the low-pressure regulator type, standard 40 um filtration and a differential-pressure drain that bleeds condensate automatically as the pressure differential across the element builds. The aluminium alloy bowl suits this largest frame, a round external gauge reading in bar is fitted, and a reverse (check) valve is included so downstream pressure is held if the supply drops. No mounting bracket is supplied with this configuration.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as standard and G or NPT threads to order, plus drain, filter-grade, gauge and reverse-valve choices. 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.

|---|---|
| 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| 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.

Feeding a light-clamping or forming press that works at reduced set pressure, where the low-pressure regulator type and 1 in ports keep the circuit supplied and the check valve holds the setting if the supply dips.
Conditioning the air feeding conveyor actuators and gripper cylinders on a bottling line, with 40 um filtration protecting valves and the differential-pressure drain clearing condensate without daily manual attention.
Mounted at the machine inlet of weaving or spinning equipment to filter and regulate the plant air supply, with the bar-scaled round gauge giving operators a clear local pressure reading.
Size 600 with 1 in NPT ports is the largest step in the GFR line, chosen when the required air delivery points to the top of the range; step down to 200/300/400 with smaller ports if your flow demand is lower. Drain options are differential-pressure (this unit, automatic in operation), fully automatic, or manual; the low-pressure regulator type in this code is for circuits set below the standard range - ask us to confirm the exact adjustment window. Filtration is 40 um standard here, with 5 um (code W) available where finer protection is needed. The fitted round gauge reads in bar; square embedded gauges and MPa/psi scales are alternatives. Thread is NPT on this unit (PT is the catalogue standard, G and NPT are order options), and the J code means no bracket is supplied.
Because GFR flow data is published as curves rather than one rated number, we cannot quote a single flow figure for this model. Send us your application details 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves, not as a single rated figure, so we do not quote one number here. Tell us your application and required delivery and we will confirm the flow data from the datasheet on request before you order.
C means a round external gauge is fitted and 3 sets its scale to bar; the standard alternative is the embedded square gauge with MPa, psi or bar scales. K means a reverse (check) valve is included, which holds downstream pressure if the upstream supply is interrupted.
