The AirTAC GFR60025LJF1T 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 GFR60025LJF1T is a GFR-series filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This 600-size unit has a 1 in NPT port, the low-pressure type regulator for circuits that run below standard line pressure, a 40 um filter element, and a differential-pressure drain on the bowl. At size 600 the bowl is aluminium alloy. A square pressure gauge scaled in MPa is fitted, no mounting bracket is included, and no reverse/check valve is fitted. Max working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow for this model is published as curves rather than a single rating, so ask us to confirm the datasheet figures against 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)). |

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.

Filtering and regulating the low-pressure air supply to rinse nozzles and air knives on a bottle-washing line, with the 40 um element keeping scale and rust particles out of the nozzles and the differential-pressure drain clearing condensate as air flows.
Supplying filtered, regulated air to 1 in main-line pneumatic valves and large cylinder actuators on a water-treatment gate or damper skid, where the low-pressure type regulator suits circuits held below standard line pressure.
Holding a gentle, stable set pressure on the pneumatic tension rollers of a paper or film converting line, where the low-pressure type regulator and 1 in NPT port serve a high-flow main drop feeding the conveyor section.
Choose the size by the port and flow you need: this 600 unit is the largest in the GFR range with a 1 in NPT port, while the 200, 300 and 400 sizes step down to smaller ports. Drain options are differential-pressure (fitted here), automatic (A) or manual (M); the filter grade is 40 um standard, with 5 um (W) available where finer filtration is needed. The low-pressure type (L) regulator is the right pick for circuits running below standard line pressure. Gauge scale can be ordered in MPa, psi or bar, thread is available as PT (standard), G or NPT, and a mounting bracket can be added if required.
Because AirTAC publishes flow for this series as curves rather than a single rated figure, send us your flow and pressure requirements and we will confirm sizing from 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 number, so we do not quote a rated flow figure. Tell us your line pressure, set pressure and air demand, and we will confirm the flow from the datasheet on request.
The L selects the low-pressure type of the GFR600 regulator, intended for circuits that run below standard line pressure; the exact adjustment range for the low-pressure type is not published in the sheet we work from, so confirm your set pressure with us and we will verify it from the datasheet. This unit also uses a differential-pressure drain, which clears the bowl automatically as air flows through the unit.
