The AirTAC GFR600C25ALJF2WT AirTAC Filter Regulator 1 in NPT 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 GFR600C25ALJF2WT is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. This size 600 unit is fitted with a 1 in NPT port, a 5 um filter element (code W) for finer particulate removal than the standard 40 um grade, and an automatic drain that expels collected condensate without manual attention. It is the low-pressure regulator type, carries an embedded square gauge scaled in psi, has no reverse/check valve, and is supplied without a mounting bracket. 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 port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, gauge scale options, G/NPT thread variants and optional brackets. Because flow is published as curves rather than a single rating, we confirm the datasheet and flow 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. 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.

Low-pressure circuits on glass container forming machines often run at modest set pressures where a standard regulator range is wasted. This low-pressure type filter regulator cleans the supply of water and fine particles and holds the reduced pressure for the forming station, with the automatic drain handling condensate between shifts.
Packaging and case-erector lines use air cylinders and actuators that need clean, dry, regulated air at moderate pressures. The 5 um element protects valve spools and cylinder seals from fine particulate, and the 1 in NPT port matches the main drop feeding the conveyor section.
Test benches and laboratory rigs frequently need stable, reduced pressure well below standard line settings. This unit filters the incoming plant air to 5 um, regulates it in the low-pressure band, and lets the operator read the setpoint directly on the psi-scaled square gauge.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start here when the line demand points to a 1 in connection; step down to 300/400 sizes where the port allows. The 5 um element (W) suits lines that need finer particle control than the standard 40 um grade. The automatic drain suits unattended or hard-to-reach installations; choose manual or differential-pressure drains where you prefer controlled or demand-based purging. The low-pressure regulator type is intended for lower set pressures - ask us to confirm the adjustment range against your setpoint. Gauge scale here is psi; MPa and bar scales are available. NPT thread is an order option alongside the PT standard and G (BSPP). A bracket can be added if this unit ships without one.
Flow for this family is published as curves, not a single rated figure, so please 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. 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 rather than a single rated figure, so no single flow number can be quoted for this unit. Send us your line demand and application details and we will confirm the flow figures from the datasheet before you order.
In the code GFR600C25ALJF2WT, the A position selects the automatic drain, which expels collected condensate on its own instead of waiting for a manual purge, and the W position selects the 5 um filter element instead of the 40 um standard grade. Both are order choices: manual or differential-pressure drains and the 40 um grade are available if your installation prefers them.
