The AirTAC GFR600C25MLJF3WTK AirTAC Filter Regulator NPT1 (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 AirTAC GFR600C25MLJF3WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 1 in NPT1 port, so it sits naturally on a 1 in main air line. The 5 um filter element (code W) gives finer filtration than the standard 40 um grade, and the manual drain lets an operator bleed collected condensate from the bowl on a chosen schedule. The regulator is the low-pressure type, and the embedded square gauge is fitted with a bar scale. A reverse/check valve is fitted, and this unit comes without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and is offered with a choice of drain type, filter grade, gauge style and scale, thread form (PT standard, with G and NPT as order options) and bracket. At size 600 the bowl is aluminium alloy. Flow is published as curves rather than a single rated figure, so 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.

Installed on a 1 in drop feeding a pneumatic press cell, it cleans the supply with the 5 um element and holds the reduced pressure the press valves were set up for, with the bar-scale gauge giving the operator a direct reading at the frame.
On a weaving shed's low-pressure loom supply, the filter stage strips water and lint carried in the shop air while the low-pressure regulator holds the gentler setting jet nozzles and fabric-handling cylinders need; the manual drain is bled at shift change.
Feeding the grip-and-place cylinders on a bottling line's case-packing manifold, it delivers filtered, regulated air to the valve stack, and the fitted reverse/check valve holds the downstream setting if upstream supply dips.
Start with the port step: this unit is the size 600 frame with a 1 in NPT1 port, the largest in the GFR range - step down to 300/400 sizes for smaller lines, but match the frame to the flow your line carries. Choose the drain to suit access: manual (as here) suits attended installations where an operator drains the bowl, while automatic or differential-pressure drains suit unattended duty. Choose the 5 um element (code W) where downstream equipment needs finer filtration than the 40 um standard. The square gauge is fitted here with a bar scale; MPa and psi scales and an external round gauge are alternatives. Thread is NPT on this unit - PT is the standard form, with G and NPT as order options - and the J code means no bracket is included. The low-pressure type (code L) is selected where the working pressure sits below the standard regulator's range; the exact adjustment range for this variant is not published, so confirm it with us. Because flow is published as curves rather than 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. 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 characteristic curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of the equipment downstream, and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code selects a manual drain: condensate collected in the aluminium alloy bowl is released by hand rather than automatically, which suits attended installations on a maintenance round. The L code makes this a low-pressure regulator variant, intended for reduced pressures below the standard type's range; the exact adjustment range for this variant is not published, so confirm it with us. The unit also carries the 5 um (W) filter element, a square gauge with a bar scale, and a reverse/check valve.
