The AirTAC GFR600C25ALJF2T 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 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 AirTAC GFR600C25ALJF2T is a filter regulator: water and particulate removal plus pressure regulation in a single body. This size 600 unit carries a 1 inch NPT port, a 40 um filter element, and an automatic drain that expels collected condensate from the aluminium alloy bowl without manual intervention. The regulator is the low-pressure type, and an embedded square gauge scaled in psi is fitted so the downstream setting can be read directly at the unit. No mounting bracket is included in this configuration.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options, drain types (differential-pressure, automatic or manual), a 5 um element option (code W), gauge scale choices and G/NPT thread variants across the range. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. 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 directional valves and clamping cylinders on an assembly press, where clean, moisture-drained air at a stable low set pressure protects the clamping sequence from drift.
A filtered and regulated air point for the diverters, pushers and gate cylinders on a carton packaging line, with the automatic drain keeping the large bowl clear during multi-shift running.
Conditioning the shop-air feed to an R&D or QC test rig, where the psi-scaled gauge lets technicians set and verify the low regulated pressure the rig requires.
Step up through sizes 200, 300, 400 and 600 against the flow your line needs - the 600 size with its 1 inch port sits at the top of the range for higher-demand circuits. Choose the drain to match maintenance reality: automatic (this unit) empties the bowl on its own, manual needs an operator, and the differential-pressure default opens only when the element loads up. The standard element is 40 um; specify code W for 5 um where finer filtration matters. Gauge scale is selectable (MPa, psi or bar) and this unit ships with the embedded square gauge in psi. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. A bracket can be added where panel or wall fixing is needed.
One honest note before you order: flow 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 commit.
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 curves, not as a single rated figure, so there is no one number we can honestly quote. Tell us your line conditions and required flow, and we will confirm the sizing against the datasheet on request before you order.
The automatic drain expels collected condensate from the bowl on its own, so the unit suits installations that are not checked daily. The alternatives are a manual drain, which an operator opens periodically, and the differential-pressure drain (the catalogue default), which opens only once the element loads up. This unit is supplied with the automatic drain.
