The AirTAC GFR600-25LJC2WK AirTAC 1 in Filter Regulator, Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR600-25LJC2WK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a 1 inch PT port, a fine 5 um filtering element (code W), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, an external round gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the supply is lost. It is the low-pressure type, intended for circuits regulated below the standard range, and is supplied without a mounting bracket. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain, filter-grade, gauge, thread and bracket options to match. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

On a carton-sealing or bag-forming line running at reduced pressure, this unit filters the shop air to 5 um and holds a steady low regulated supply to the sealing and forming cylinders, with the check valve holding the circuit if the main supply drops.
For bench test rigs and pilot plants, the 5 um element protects sensitive regulators, transducers and actuators from water and fine particles, while the low-pressure regulation and psi gauge let operators set and read a gentle, stable test pressure.
On a conveyor diverting and gating application, this filter regulator conditions the air feeding the diverters and stop gates, the differential-pressure drain keeps condensate off the valves, and the check valve prevents back-feed through the supply.
Step up through sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this unit is the top of the range at 1 inch PT. Choose the 40 um standard element for general protection or the 5 um element (as fitted here) where downstream valves and cylinders need finer air. Drain options are differential-pressure (default, as here), automatic, or manual. Gauges: an embedded square gauge is standard, with an external round gauge optional in MPa, psi or bar scales; this unit carries the round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available to order; brackets are optional (this configuration omits it) and the reverse/check valve (code K) is fitted. The low-pressure type suits circuits regulated below the standard range. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
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 this family as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, regulated setpoint and the consumption of the equipment downstream, and we will confirm the datasheet curve figures for this exact model on request.
The L code marks the low-pressure version of the GFR regulator section, intended for circuits regulated below the standard range. Its exact adjustment range is not published on the sheet we work from, so confirm your setpoint with us and we will verify suitability on request. Everything else on this unit decodes normally: 5 um element, differential-pressure drain, round psi gauge, check valve, 1 inch PT port.
