The AirTAC GFR600C25MJNWT 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 GFR600C25MJNWT is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is fitted with a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain for the bowl, and no gauge. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the maximum working (inlet) pressure is 1.0 MPa (145 psi). Because it is size 600, the bowl is aluminium alloy. Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, gauge and thread options, and optional brackets. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures 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.

Installed at the wall drop feeding a manufacturing cell, the unit strips water and fine particulate from the shop-air main and holds a steady regulated pressure for the cell's valves and cylinders. The manual drain is emptied during scheduled rounds, and the 1 in NPT port suits a main header feed.
Mounted ahead of a CNC machine's pneumatic panel, it cleans the incoming compressed air and sets the pressure the machine builder specifies for clamps, tool changers and chip-blowing circuits. The 5 um element protects the machine's own valves from fine contamination.
Placed on the supply to a packaging conveyor's cylinders and air-driven sealers, it keeps water out of the actuators and holds the working pressure steady so case clamping and sealing stay repeatable through the shift. The aluminium size 600 bowl handles the higher demand at the line's inlet.
Step up or down through the GFR sizes (200, 300, 400, 600) to match the port and the flow your line needs; size 600 with a 1 in port sits at the top of the range for high-demand circuits. This unit carries the 5 um element (code W) instead of the 40 um standard, so choose it where downstream valves and instruments need finer particulate removal. The manual drain (code M) means an operator opens the drain periodically rather than relying on an automatic or differential-pressure mechanism - a good fit where bowls are checked as part of a routine. No gauge is fitted (code N); if you want to read the set pressure at the unit, order a variant with a gauge or add one downstream. Thread here is NPT (code T); PT is the catalogue standard and G (BSPP) is also an order option. No mounting bracket is included with this configuration. Flow for the GFR series is published as curves, not a single rating, so send us your flow and pressure requirements 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 series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your required flow and working pressure and we will confirm the figures from the datasheet and check the sizing for your application on request.
The M in the code is the manual drain: the aluminium bowl is emptied by opening the drain by hand, which suits installations checked on a routine, instead of the differential-pressure or automatic drain options. The N means no gauge is fitted, so the set pressure is read on a gauge elsewhere in the circuit; gauge-equipped GFR variants can be ordered if you want the reading at the unit.
