The AirTAC GFR600C25LF1T 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 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 GFR600C25LF1T is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single body. This configuration is the size 600 frame with a 1 in NPT port, the 40 um standard filtration element, and the differential-pressure drain that is the default for this family. Regulation is the low-pressure type (code L), and a square pressure gauge reading in MPa is fitted so the setpoint is visible at the unit. The 600-size bowl is aluminium alloy, a mounting bracket is included, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT (standard), G and NPT threads, with differential-pressure, automatic or manual drains, a 5 um element option (code W), embedded square or external round gauges in MPa, psi or bar scales, and an optional reverse/check valve. Flow for this size is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Filtered, regulated air to powder spray guns and fluidizing hoppers on a coating line, where the low-pressure regulator type suits guns and hoppers run at reduced settings and the 1 in port ties into a main drop.
Pressure-controlled air to air knives and blow-off nozzles above a bottling conveyor, with the differential-pressure drain handling condensate that carries over from the plant ring main.
Clean, regulated purge air for laboratory glassware dryers and environmental chambers that operate below normal plant pressure, with the 40 um element protecting the chamber pipework and nozzles.
Choose the size and port against the duty your line needs: 600 is the largest GFR frame, and this unit carries a 1 in NPT connection (PT is the catalogue standard thread; G and NPT are order options). The L in the code selects the low-pressure regulator type for circuits run at reduced pressure; the exact adjustment range for that type is not published in the material we hold, so confirm it with us if your setpoint is critical. The drain here is the differential-pressure default, with automatic (A) and manual (M) available to order. Filtration is the 40 um standard element, with 5 um as code W. The fitted square gauge reads in MPa; psi and bar scales and an external round gauge are alternatives. Because flow is published as curves and not a single rating, send us your application conditions and we will confirm sizing from the datasheet 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 GFR600 as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure, downstream pressure setting and the equipment you are feeding, and we will confirm the flow from the datasheet for this exact configuration before you order.
It selects the low-pressure regulator type, intended for circuits that run at reduced pressure rather than the standard adjustment range. The exact adjustment range for the low-pressure type is not published in the material we hold, so confirm it with us if your setpoint is critical. Everything else in the code decodes normally: 1 in NPT port, 40 um element, differential-pressure drain, square MPa gauge and included bracket.
