The AirTAC GFR60025LJF2GK AirTAC Filter Regulator G1 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 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 GFR60025LJF2GK is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1 (1 in) BSPP port, a 40 um standard filter element, a differential-pressure drain, and the low-pressure regulator type for applications that operate at reduced set pressures. A reverse/check valve is fitted, the embedded square gauge reads in psi, and the size-600 bowl is aluminium alloy. No mounting bracket is included with this version.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um element option (code W), gauge scale choices, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeds filtered, regulated air at a reduced set pressure to clamping cylinders on a CNC fixture, with the 40 um element keeping pipe scale and condensed water out of the clamp circuit and the check valve holding the circuit if upstream supply dips.
Sits at the drop point where the 1 in main feeds a packaging line's diverters, sealers and pushers, cleaning the shop air and holding a stable reduced pressure so cylinders stroke consistently through the shift.
Installed at the take-off from a factory compressed-air ring main to supply a process header that runs below standard line pressure, combining water and particulate removal with low-pressure regulation in one body at the 1 in connection.
Start with the port step: this unit is the size-600 frame with a G1 (1 in) connection, the largest in the GFR range - step down to GFR200/300/400 if your line runs smaller ports and lower air demand. The low-pressure type (code L) is the regulator choice where the process works at reduced set pressures; the exact regulation range for the low-pressure GFR is not published in the catalogue, so confirm it with us against your setpoint. The 40 um element is the standard grade - specify the W suffix if your application needs the 5 um option. The differential-pressure drain bleeds accumulated water automatically as flow passes the unit; automatic (A) and manual (M) drains are the alternatives. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are available. Thread options are PT (standard), G and NPT, and a mounting bracket can be ordered if you need panel fixing. Because flow is published as curves rather than a single rated figure, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR performance as flow curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and the air demand of the equipment downstream, and we will confirm the sizing from the datasheet curves on request before you order.
The L marks the low-pressure regulator type, intended for applications operating at reduced set pressures; the exact regulation range for the low-pressure GFR is not published in the catalogue, so confirm it with us against your setpoint. This unit also has the differential-pressure drain (blank position in the code), which bleeds collected condensate automatically as air flows through the bowl - the alternatives are the automatic drain (A) and the manual drain (M).
