The AirTAC GFR60025LJC3T 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 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 GFR60025LJC3T is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 40 um element, then regulates downstream pressure, and it is built as the low-pressure type for circuits that run at reduced working pressure. This configuration has 1 in NPT ports, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an external round gauge reading in bar.
This is a genuine AirTAC part from the GFR600 size range, the largest of the G-series sizes (200, 300, 400, 600), with the 600-size bowl in aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Low-pressure regulation ranges and flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet for your operating point 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. |
| (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 a production hall's low-pressure air distribution from a main compressor line, filtering water and particulate out of the supply while holding the circuit at the reduced working pressure the header is designed for.
Sits at the drop feeding pneumatic cylinders and air tools in an assembly cell, cleaning the shop air and letting the cell set its own regulated pressure independently of the main header.
Conditions and regulates compressed air at a heavy-vehicle service bay or fleet maintenance line, where the 1 in NPT ports handle the bay's high-volume supply and the drain keeps condensate out of downstream test equipment.
Size 600 with 1 in NPT ports is the right step when your line's flow demand sits at the top of the G-series range; step down to 300 or 400 if your curve shows the smaller ports are sufficient. The 40 um element is the standard grade for general plant air - choose the W-coded 5 um element only where downstream equipment needs finer filtration. The differential-pressure drain suits lines with steady flow; for intermittent or low-flow duty consider the automatic-drain variant, and for a simple manual check the M-coded version. This unit carries the external round gauge with a bar scale (MPa and psi scales are order options), and NPT is the thread here - G (BSPP) and PT are the other catalogue options. No mounting bracket is included with this code (J = no bracket).
Flow for this family is published as curves, not a single rated figure, 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.
We do not quote a single rated flow figure because AirTAC publishes G-series flow as curves, not as one rated number. Tell us your flow demand and working pressures and we will confirm against the datasheet whether this 1 in NPT, size-600 unit suits your application before you order.
The L in the code marks this as the low-pressure regulator type, intended for circuits that operate at reduced working pressure; the exact regulation range for the low-pressure type is not published in our sheet, so ask us to confirm it for your setpoint. Drainage is differential-pressure: condensate collected in the aluminium bowl is bled off automatically as air flows through, with no manual draining needed.
