The AirTAC GFR60025LJC2G AirTAC Filter Regulator G1 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 GFR60025LJC2G is a size 600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1 (1 inch) G-thread port, a 40 um standard filter element, a differential-pressure drain that bleeds condensate automatically as flow passes through, and a low-pressure regulator type for circuits that run below standard line pressures. The aluminium alloy bowl suits the larger 600 size, a round external gauge scaled in psi is fitted, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 inch to 1 inch, and options include manual or automatic drains, a 5 um (W) element, square or round gauges scaled in MPa, psi or bar, and PT, G or NPT threads. Flow for this unit is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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.

Installed at the 1 inch main drop feeding a carton-forming and wrapping line, it strips water and pipe scale from the shop-air supply and holds a steady low regulated pressure to the film-tension and sealing cylinders.
Mounted ahead of a valve manifold on a workholding fixture, it delivers filtered air to the clamps while the low-pressure regulator type keeps actuation pressure in the band the fixture designer specified.
Fitted at the point of use on a bottling conveyor, it conditions air for the gate and pusher cylinders, with the differential-pressure drain clearing condensate that collects during continuous shift running.
Start with the port step: this unit is the size 600, 1 inch G-thread version, the largest in the GFR range - step down to 300/400 sizes for smaller lines, but match the port to the main air drop rather than oversizing the body. Drain choice matters: this unit uses the differential-pressure drain (the default); automatic (A) and manual (M) versions exist if you want continuous bleed-free operation or periodic manual dumping. The 40 um element is standard here; specify the W code if your valves need the 5 um grade. The fitted gauge is the external round type scaled in psi; square embedded gauges and MPa or bar scales are the alternatives. Thread is G (BSPP) on this code - PT is the catalogue standard and NPT is orderable. Brackets are optional; this J-coded unit ships without one.
One honest note on sizing: AirTAC publishes flow for the GFR series as curves, not a single rated number, so send us your required flow and line pressure and we will confirm the correct size 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 figure, so there is no one number we can honestly quote. Send us your required flow and operating pressure and we will confirm the sizing from the datasheet on request before you order.
The L marks the low-pressure regulator type, intended for circuits that run below standard line pressures; its exact adjustment range is not published in the summary data, so we confirm it on request. Drainage is the differential-pressure type (the default), which bleeds the aluminium bowl automatically as air flows through - automatic (A) and manual (M) drain versions are available under other codes.
