The AirTAC GFR600C25ALJF2TK AirTAC Filter Regulator NPT 1 in 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 See datasheet 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 GFR600C25ALJF2TK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit carries a 1 in NPT port, an automatic drain that ejects collected condensate without anyone opening the bowl, a 40 um standard filter element, an embedded square gauge reading in psi, a fitted reverse/check valve and the low-pressure regulator type. Because it is size 600, the bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating 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 ports from 1/8 in to 1 in, drain choices of differential-pressure (default), automatic or manual, 40 um standard or 5 um (W) filtration, embedded square gauges with MPa, psi or bar scales plus an optional external round gauge, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure for your application before you order.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

Feeding clean, regulated low-pressure air to a bank of pneumatic clamps and grippers on a car trim assembly line. The automatic drain keeps condensate out of the valves through humid summer shifts, and the check valve holds the downstream setting if the main supply dips.
Conditioning the air feed to a shot-blast or vibratory-finishing cabinet, where moisture in the media line ruins the blast pattern. The 1 in port suits a dedicated cabinet take-off, and the psi gauge lets an operator set and verify blasting pressure at the cabinet.
Serving as the conditioning and pressure-setting point on a bottling hall take-off that feeds conveyor stop-and-gate cylinders. The automatic drain protects the actuators between maintenance rounds, and the low-pressure regulator type matches the modest setting these drives run at.
The real choices on this family are all decodable from the code. Size steps 200/300/400/600 set the port and flow path - this unit is the top of the range at 1 in NPT, so step down a size if your line runs smaller ports. Drain type: differential-pressure is the default, automatic (this unit, code A) suits bowls mounted out of easy reach, and manual (M) is available. Filter grade: 40 um standard element, or 5 um with the W code where finer particulate protection matters. Gauge: the embedded square gauge is standard and this one reads psi; an external round gauge is optional with MPa, psi or bar scales. Regulator type: standard or low-pressure (L) - this unit is the low-pressure type, and its exact range is not published, so confirm it with us. Thread: PT is the standard; G and NPT are order options, and this unit is NPT. A J code deletes the mounting bracket, as on this unit.
Flow for this family is published as curves, not a single rated figure, so send us your application details 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.
AirTAC publishes GFR flow as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details - port size, line pressure and the equipment you are feeding - and we will confirm the flow and sizing against the datasheet before you order.
The A in the code fits an automatic drain, which ejects collected condensate on its own - useful where the unit is mounted out of easy reach. Differential-pressure drain is the catalogue default and a manual drain (code M) is also available. Tell us which drain your installation needs and we will confirm the corresponding configuration details.
