The AirTAC GFR600C25MLJC2WTK 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 GFR600C25MLJC2WTK is an AirTAC GFR filter regulator: a 5 um filter element and a pressure regulator combined in one body, sized 600 with a 1 in NPT port. The W code selects the finer 5 um element instead of the 40 um standard, and the M code gives a manual drain, so the bowl is emptied by hand rather than automatically. This is the L low-pressure type, intended for duty at reduced downstream pressures; the exact setting range for the low-pressure type is not published, so confirm it against your setpoint before ordering. The C2 code adds an external round gauge reading in psi, the K code fits a reverse (check) valve, and the J code means the unit is supplied without a mounting bracket. At size 600 the bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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, in PT (standard), G (BSPP) or NPT thread, with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and bracket or no bracket. Rated flow for this series is published as curves rather than a single figure, so send us your flow requirement and we will confirm sizing from the datasheet 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.

On a CNC fixture circuit, this unit filters the shop air to 5 um and holds a low, stable clamp pressure so workholding stays consistent through the cycle. The manual drain suits a fixture cabinet that an operator passes each shift.
Quarter-turn air actuators on a water-treatment or chemical dosing skid need clean air at a reduced pressure. This filter regulator conditions the supply at the skid edge, and the round psi gauge gives technicians a readable setpoint.
Filling, capping and carton-sealing stations on a packaging line often run at reduced pressure. Feeding those stations through this 1 in filter regulator keeps the air dry and filtered while the low-pressure type matches the reduced setpoint.
Choose the size by port and flow: sizes 200 through 600 step up in both port diameter (here 1 in NPT) and flow capacity, so match the size to the largest flow your line needs at working pressure. Decide the drain: manual (this unit) suits installations someone can reach for routine draining, while automatic or differential-pressure drains suit inaccessible or unattended points. Pick the element grade: 40 um standard for general protection, or 5 um (W, this unit) where downstream valves and instruments need cleaner air. Select the gauge scale - MPa, psi or bar - and the thread: PT is the standard, with G (BSPP) and NPT as order options. Bracket or no bracket is also a code choice. Flow for this series is published as curves, not a single rating, so 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 we do not quote a number here. Send us your port size, working pressure and required flow, and we will confirm sizing from the datasheet on request.
The M code in this model specifies a manual drain: the aluminium alloy bowl is emptied by hand, which suits attended installations. The same size is also available with an automatic or differential-pressure drain - just order the corresponding code. For this low-pressure type the exact regulator setting range is not published, so confirm your setpoint with us before ordering.
