The AirTAC GFR600C25MLNWTK 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 GFR600C25MLNWTK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit carries a 1 in NPT port, a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, a reverse/check valve, and the low-pressure regulator type. No gauge is fitted (code N), and the mounting bracket is included.
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, and options for drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge and scale, thread (PT standard, G and NPT to order) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Positioned ahead of the clamp valves, this unit strips water and chips-laden particulate down to 5 um and holds a reduced clamp pressure on fixtures that must not over-grip delicate workpieces. The manual drain is emptied as part of the shift-start routine, and the check valve helps hold the downstream circuit during supply dips.
On a packaging line's main 1 in air drop, this filter regulator feeds cylinders and grippers with clean, regulated air. The 5 um element protects the directional valves and gripper seals, while the low-pressure regulator type suits circuits running well below full line pressure.
Feeding blow-off nozzles and cooling jets beside an injection molding press, this unit filters the shop air to 5 um so nozzles stay clear of water and debris, and regulates it down to the gentle pressure the parts need. The manual drain is opened during scheduled maintenance checks.
Size and port set the air capacity: this unit is size 600 with a 1 in NPT port, the largest step in the range; step down to 200, 300 or 400 for smaller lines. Drain choice matters: the manual drain fitted here needs periodic emptying, while automatic and differential-pressure drains handle condensate without attention. Filter grade: 40 um is standard; the 5 um element fitted here suits finer protection. A gauge (embedded square, or external round, scaled in MPa, psi or bar) can be ordered; none is fitted on this code. Thread: PT is the standard, with G (BSPP) and NPT as order options - this unit is NPT. Flow is published as curves, not a single rating, so send us your flow and pressure conditions 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 GFR600 flow as curves against inlet pressure and pressure drop, not as a single rated figure, so we do not quote a number here. Send us your line pressure, regulated setpoint and air consumption, and we will confirm the flow and datasheet figures for this exact model on request.
Code M means the aluminium alloy bowl carries a manual drain: open it periodically to discharge collected condensate. The same size 600 unit is available with an automatic or differential-pressure drain, and with the standard 40 um element if you do not need the finer 5 um filtration fitted on this code.
