The AirTAC GFR600C25AJNWTK 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 GFR600C25AJNWTK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built with a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that sheds collected condensate without manual attention, and an aluminium alloy bowl - the material used across the 600 size. No pressure gauge is fitted on this variant, and a reverse/check valve is included to hold downstream pressure if the upstream supply drops. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.15-0.9 MPa (20-130 psi) of adjustment, and the operating temperature range is -5 to 70 C (non-freezing). Mounting bracket is not included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge and thread options (PT is the standard; G and NPT are order options), and bracket or no-bracket variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 ahead of a CNC machining centre's solenoid valves and pneumatic clamps, this filter regulator removes water and fine particulate with the 5 um element and holds a set supply pressure, while the automatic drain clears condensate between shifts without operator attention.
Feeding the cylinders and vacuum ejectors on a packaging conveyor line, the unit keeps actuator pressure steady at the setpoint and the reverse/check valve holds the downstream circuit if the plant air dips, protecting an in-cycle pick-and-place sequence.
At a high-demand assembly station running impact wrenches and air clamps off a 1 in trunk line, the size 600 body with its aluminium alloy bowl and automatic drain conditions the shop air and regulates it to the pressure the tools were set up for.
Step up through the GFR sizes (200, 300, 400, 600) as your port and air demand grow; this unit sits at the top of the range with a 1 in NPT port, so match it to lines running large-bore supply. Choose the drain to suit access: automatic (this unit) for unattended duty, manual where you want controlled blowdown, or the differential-pressure default. Choose 40 um for general protection or 5 um (this unit) where finer filtration matters downstream. Gauges are an ordering choice - embedded square or external round, with MPa, psi or bar scales - and this variant ships without one. Thread is PT as standard; G (BSPP) and NPT (this unit) are specified at order, and the bracket is optional. Because flow is published as curves and not a single rating, 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 GFR600 flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of the equipment downstream, and we will confirm the sizing against the datasheet on request before you order.
Correct: the N in the code means no gauge is supplied with this unit. AirTAC GFR regulators can be ordered with an embedded square gauge or an external round gauge, and the gauge scale is selectable (1 = MPa, 2 = psi, 3 = bar). Specify the gauge option when ordering if you want a fitted pressure indication.
