The AirTAC GFR600C25MNWT AirTAC Filter Regulator, NPT 1 in, 5 um 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 GFR600C25MNWT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit carries 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 fitted. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). At size 600 the bowl is aluminium alloy, and the unit operates from -5 to 70 C in non-freezing conditions.
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 manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, gauge and thread options, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Clean, regulated air feeding pallet clamps, tool-change cylinders and part-ejection actuators on a machining centre, with the 5 um element protecting fine-tolerance valve spools.
Filtered and regulated air for stopper gates, pusher cylinders and diverters along a filling and bottling conveyor, with the manual drain emptied during scheduled line cleaning.
Stable regulated pressure for carton-forming and case-sealing cylinders on a packaging line, where the 1 in port serves a high-demand drop from the main air header.
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. Choose the drain to match the installation: manual drain (this unit) suits accessible, regularly serviced positions, while automatic or differential-pressure drains suit less accessible ones. Pick 5 um filtration (this unit) when downstream equipment needs finer protection than the 40 um standard element. Gauges are optional - this configuration ships without one, and a gauge can be selected on other variants. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the datasheet curve and sizing against your required flow 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 performance curves rather than a single rated figure, so we do not state a flow number. Tell us your application and required flow and we will confirm the datasheet curve and check the sizing for you before you order.
The M in the code specifies a manual drain: condensate collected in the bowl is released by hand during servicing. Choose manual where the unit is easily accessible and checked routinely; choose an automatic or differential-pressure drain variant where the installation is hard to reach or visited infrequently.
