The AirTAC GFR600C25MLJC3WTK AirTAC Filter Regulator NPT1 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 GFR600C25MLJC3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1 in NPT port for high-flow lines, a fine 5 um filter element (code W), a manual drain on the bowl, the low-pressure regulator type, a fitted round gauge scaled in bar, and an integrated reverse/check valve. The bowl on size-600 units is aluminium alloy, and this unit is ordered 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 to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure for your application before ordering.

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.

On a weaving or finishing line supplied from a 1 in plant-air header, this unit filters the supply to 5 um and holds a reduced, stable pressure for clamping and hold-down actuators, with the check valve holding the downstream circuit if upstream pressure dips.
Big diaphragm and piston-actuated process valves need a clean, steady, lowered supply pressure. Fed through the 1 in NPT port, this unit conditions the air to 5 um and regulates it to the actuator's working band, with the bar gauge giving the operator a direct local reading.
At a bottling or packaging conveyor where gate and diverter cylinders run on a large-bore air supply, this filter regulator removes water and fine dirt from the header air and drops the pressure to what the gating circuit needs, with manual draining done during scheduled checks.
Size 600 with a 1 in port is the largest step in the GFR range; step down to 300 or 400 if your line flow is modest, since port size should follow the air demand of the circuit. The 5 um element (code W) suits downstream equipment sensitive to fine particles; the 40 um standard element is the usual choice for general plant air. The manual drain means an operator opens the bowl drain periodically, which suits attended installations; automatic or differential-pressure drains are available on other variants where the unit is hard to reach. The low-pressure regulator type is selected where the working band sits below the standard range - the exact adjustment range for this type is not published in our sheet, so confirm it with us. The round bar gauge is fitted as coded; square or external round gauges with MPa, psi or bar scales are the other options. NPT is the thread on this unit, with PT and G available to order, and the J code means no mounting bracket is supplied.
Because flow for this family is published as curves and not as a single rated figure, we cannot quote a number here - 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 flow for the GFR family as curves, not as a single rated figure, so we do not quote a number here. Send us your line size, upstream pressure and required downstream flow, and we will confirm the sizing against the datasheet before you order.
The M code in the model means the bowl drain is opened by hand, so condensate is removed during routine checks - automatic and differential-pressure drains are the alternatives on other GFR variants. The L code marks the low-pressure regulator type, intended for working bands below the standard range; its exact adjustment range is not published in our sheet, so confirm it with us for your setpoint.
