The AirTAC AirTAC GFR600C25ALF2W Filter Regulator 1in PT 5um 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 GFR600C25ALF2W is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 600 unit with a PT1 (1 in) PT-threaded port, an automatic drain that discharges collected condensate without manual attention, a 5 um filter element (the finer of the two published grades), the low-pressure regulator type, and a factory-fitted embedded square gauge reading in psi. A mounting bracket is included, and the bowl on this size is aluminium alloy.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, standard or low-pressure regulation, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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 conditioning ahead of air tools and pneumatic clamps on an assembly line, where the low-pressure regulator type holds a modest working pressure and the 5 um element protects tools from water and fine dirt.
Conditioning the supply to cylinders and grippers on packaging and palletising conveyors: the 1 in PT port suits a main drop, the automatic drain keeps condensate off the actuators, and the psi gauge gives operators a local setpoint reading.
Supplying instrument air to pilot-scale process skids and test rigs that run below standard regulator settings, where the low-pressure type, aluminium alloy bowl and square psi gauge support controlled, monitored low-pressure operation.
Start from the port and size: this unit is the largest GFR size, 600, with a 1 in PT port, so match it to the line size and the flow your circuit needs. Choose the drain to suit access: automatic (as here) suits units mounted where manual draining is impractical, manual suits attended installations, and the differential-pressure default drains on a pressure drop. Filtration is 5 um here; the standard grade is 40 um if the downstream equipment tolerates coarser air. The regulator is the low-pressure type - its adjustment range is not published as a single figure, so confirm it against your set pressure before ordering. The gauge reads psi; MPa and bar scales are the other catalogue options. PT is the standard thread; G (BSPP) and NPT are order options. Flow is published as curves, not a single rating - send us your flow and pressure requirements 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 GFR flow as performance curves, not 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 the GFR600 at 1 in PT meets them before you order.
The L code is the catalogue variant of the GFR regulator intended for lower set pressures than the standard type; the exact adjustment range for this variant is not published as a single figure, so confirm your setpoint with us before ordering. The automatic drain is separate: it ejects collected condensate on its own, with no manual draining required.
