The AirTAC GFR600-25 AirTAC Filter Regulator NPT 1 in 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 PT1" ports, a automatic 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 GFR600-25 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This 600-size unit has a 1 in NPT port, an automatic drain, a 40 um filter element and an aluminium alloy bowl. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), a round gauge scaled in MPa is fitted, and a reverse/check valve is built in. Mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 in, and options include manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G or NPT threads and low-pressure types. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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.

Point-of-use air preparation for a stamping and assembly cell: the 1 in NPT connection sits on the main drop, the 40 um element strips water and swarf from the plant supply, and the regulator holds a steady downstream pressure to the cell's actuators. The automatic drain handles condensate on a line that runs unattended.
Clean, regulated air for pneumatic clamps, tool-changer cylinders and chip-clearing jets on a machining centre. The filter stage protects the valves and cylinders from particulate and moisture, the check valve holds the set pressure if the supply dips, and the MPa gauge gives the operator a clear setpoint readout.
Supply branch for pneumatically actuated butterfly and diaphragm valves on a filling or bottling line. The regulator keeps actuator pressure consistent for repeatable valve stroking, the automatic drain protects the line during washdown-heavy shifts, and the aluminium bowl suits the larger 600-size flow path.
Size the unit by the port step: 600 is the largest G-series size, with a 1 in port for the highest flows in the family. Choose the drain to match the installation - automatic (this model, code A) empties the bowl without attention, manual needs a periodic push, and the default differential-pressure drain bleeds whenever the pressure drop across the element rises. Filter grade is 40 um standard; order code W for 5 um when finer filtration matters. Gauges come embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit carries the round MPa gauge. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. A bracket is included. Flow 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
Flow for the GFR600 is published as curves in the AirTAC datasheet, not as a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm from the datasheet whether this 1 in unit is correctly sized for your application.
This unit carries code A, an automatic drain that expels collected condensate without operator action - useful on unmanned or hard-to-reach installations. The alternatives in the GFR range are a manual drain (code M), which empties only when pressed, and the default differential-pressure drain, which bleeds automatically as the pressure drop across the element rises. Choose based on how often the bowl can be serviced.
