The AirTAC GFR60025LJF2K AirTAC Filter Regulator 1 in PT, 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 GFR60025LJF2K is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the low-pressure type, built for lines that run below standard working pressure, with a 1 in PT (BSPT-profile) port for high-flow mains. It carries the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, and a reverse/check valve fitted so downstream pressure is held if the supply side drops. Because this is size 600, the bowl is aluminium alloy rather than polycarbonate, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, standard or low-pressure regulation, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet and sizing for your application.

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.

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.

On a food or consumer-goods packaging line running intentionally below standard pressure, this low-pressure GFR filters water and scale out of the 1 in main and holds the header at the setpoint the machines were tuned for, with the psi gauge giving operators a visible line reference.
A big clamping or forming press draws heavily on the shop-air ring main; this size-600 unit cleans the supply at the machine inlet and regulates it to the press circuit, while the reverse/check valve keeps the press from losing position if upstream pressure dips mid-cycle.
Pneumatic diverters, gate actuators and hold-downs along a bottling or parcel conveyor share one supply leg; this filter regulator removes condensate and particulate at the head of the leg, sets the pressure the actuators were sized for, and its differential-pressure drain clears accumulated water as air flows past.
Start with the port step: this unit is size 600 with a 1 in PT port, the largest in the GFR range, so match it to a main line that genuinely needs that bore - stepping up to 1 in on a small line adds cost without benefit. The low-pressure (L) type is the decodable choice for circuits that run below standard regulator settings; its exact adjustment range is not published in our sheet, so confirm it against your working pressure before ordering. Drain is differential-pressure as standard here, with automatic (A) and manual (M) available; filtration is 40 um standard, with 5 um (W) if downstream equipment needs finer air. Gauge is the embedded square type reading psi, with an external round gauge and MPa or bar scales as options, and a reverse/check valve (K) is fitted. Thread is PT as standard; G and NPT are order options. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm sizing from the datasheet before you commit.
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 GFR600 as performance curves rather than a single rated figure, so there is no one number we can honestly quote. Send us your line pressure, downstream setpoint and expected air demand, and we will confirm the sizing from the datasheet on request before you order.
L marks the low-pressure type of regulator: this unit is built for circuits that run below standard working pressure. Its exact adjustment range is not published in our sheet, so treat the working pressure you need as the deciding question and ask us to confirm the range from the datasheet. Everything else in the code decodes normally: 600 size, 1 in PT port, 40 um filter, differential-pressure drain, square psi gauge, reverse/check valve fitted, no bracket.
