The AirTAC GFR600-25T 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 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 GFR600-25T is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single 1 in NPT body. This configuration has the standard 40 um filter element, an automatic drain that expels collected condensate without manual attention, and a round pressure gauge with an MPa scale. The size 600 aluminium alloy bowl suits larger installations, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, plus choices of drain type, 5 um or 40 um filtration, gauge style and scale, thread (PT standard, G and NPT as options) and bracket. Flow is published as curves rather than a single rating, so we confirm datasheet figures on request - just ask 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.

Dropped from a 1 in distribution main to feed a production bay, the GFR600-25T filters line-scale water and rust out of the supply and holds a steady regulated pressure to every machine on that leg, with the automatic drain keeping the aluminium bowl clear between shifts.
CNC machines and their pallet changers want clean air at a set pressure. A GFR600-25T at the cell inlet removes particulate and condensate and lets maintenance set one regulated pressure for the whole cell, with the MPa gauge giving a local reading.
Cylinder-actuated gates and diverters along a packaging conveyor share one regulated feed. A GFR600-25T on the header filters the incoming air and holds the pressure the actuators were set up for, so valve timing stays consistent down the line.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start here when the pipe run and expected air demand are at the top of the series. Match the size to required flow using the published curves - we confirm the right size against your application on request. This unit has an automatic drain, the low-maintenance choice when the bowl sits where manual draining is awkward or easily forgotten; manual and differential-pressure drains are available in the family if you prefer. The standard 40 um element suits general air preparation; specify the W variant if you need 5 um. The round MPa gauge is fitted here, with square embedded gauges and psi or bar scales also offered. PT is the standard thread; G and NPT are catalogue options to order, as specified on this NPT model. A bracket is included.
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, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air demand and we will confirm the sizing from the datasheet curves on request before you order.
The A in the code selects the automatic drain, which expels collected condensate from the bowl without anyone opening it - useful for bowls mounted high or out of easy reach. The family also offers a manual drain (code M) and a differential-pressure drain (blank) if you would rather drain on demand.
