The AirTAC GFR600-25JF1T 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 PT1" 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 GFR600-25JF1T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This size 600 unit is threaded 1 in NPT, carries a 40 um filter element, and drains condensate by differential pressure - the bowl bleeds as air flows across the element. The standard regulator covers a 0.15-0.9 MPa (20-130 psi) setting range, an embedded square gauge reading in MPa is fitted, and no reverse/check valve is included. The aluminium alloy bowl suits this 600 frame, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in. Options include a 5 um element (code W), automatic or manual drains, psi or bar gauge scales, an external round gauge, G (BSPP) or NPT threads, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

Filter and regulate the 1 in branch feeding clamps, fixtures and tool-change cylinders in a machining cell; the 40 um element keeps pipe scale and condensate out of directional valves.
Supply filtered, regulated air to grippers, stopper cylinders and diverters on a bottling line; the differential-pressure drain bleeds accumulated water from the aluminium alloy bowl during production.
Regulate shop air at 1 in drops serving pneumatic impact wrenches and nutrunners on a truck assembly line, holding a steady setpoint between 20 and 130 psi as bays start and stop.
Choose the size by port and required flow: this 600 frame takes a 1 in NPT connection for the largest branch lines, while smaller frames (200/300/400) step down through 1/8 to 3/4 in. Drain choice matters: the default differential-pressure drain suits steady flow, the automatic (A) drain suits intermittent flow, and the manual (M) drain gives operator control. The standard 40 um element protects most actuators and valves; specify the 5 um W grade where finer filtration is needed. Gauge scale can be MPa (as fitted here), psi or bar, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. This configuration has no bracket and no reverse/check valve. Because flow is published as curves rather than a single rating, 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. 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 curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow and full datasheet figures for this 1 in NPT filter regulator on request.
This unit uses the differential-pressure drain: as air flows through the 40 um element, the pressure drop bleeds condensate from the aluminium alloy bowl. Automatic (code A) and manual (code M) drain versions are available to order for intermittent-flow or operator-controlled duty.
