The AirTAC GFR600C25MLJF3T AirTAC Filter Regulator NPT1 Low-Pressure 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 AirTAC GFR600 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, so one 1-inch (NPT1) unit does both jobs in the air-preparation position. This configuration is the low-pressure regulator type with a manual drain, a 40 um standard filtration element, an embedded square gauge scaled in bar, and no mounting bracket. The bowl is aluminium alloy (size 600 is the metal-bowl size), and the maximum working inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and offers manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, square or square/round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, ask us to confirm sizing and any datasheet figure against 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.

Filtered air feeds a low-pressure regulator holding a gentle clamp pressure on pneumatic clamps, with the bar-scaled square gauge giving the setter a direct local reading at the fixture.
A 1-inch main air drop to a packaging line passes through this filter regulator, stripping water and particulate and setting a low regulated supply for the machine's air circuit.
Sorting gates and diverters on a conveyor system take their air through this unit, which cleans the supply and regulates it at a low setpoint for consistent gate movement.
Step up through the G-series sizes (200, 300, 400, 600) and port codes (1/8 to 1 inch) to match the pipe bore and air demand of the line; this unit is the 600 size with 1-inch NPT ports, the largest step in the family. Choose the drain to suit attendance: manual (this unit) needs periodic bowl draining by an operator, while automatic and differential-pressure drains handle it in service. Pick 40 um for general air preparation or 5 um (code W) where finer filtration is wanted; select the gauge scale (MPa, psi or bar - this unit is bar); and order PT or G thread as an alternative to this NPT version. A mounting bracket can be added on variants that carry it - this code is the no-bracket (J) version. Flow is published as curves, not a single rating, so send us your air demand and let us confirm the correct size 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 this series as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code is a manual drain: accumulated water must be drained from the bowl by an operator at intervals. If you prefer the bowl to discharge automatically, the GFR600 is also available with an automatic (A) or differential-pressure (blank) drain - note that the regulator adjustment range differs by drain type, and for this low-pressure (L) type the exact range is not published, so confirm it with us on request.
