The AirTAC GFR60025LJC2TK 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 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 GFR60025LJC2TK is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the low-pressure type, fitted with an external round gauge scaled in psi, a reverse/check valve to hold the set pressure against backflow, and a differential-pressure drain that bleeds condensate from the aluminium alloy bowl as flow passes through. The 1 in NPT port suits a main air line serving several downstream devices.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with a choice of thread (PT standard, G or NPT to order), drain type, 40 um or 5 um filtration, gauge style and scale, and bracket options. Flow is published as curves rather than a single rating, so ask us to confirm the 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.

On a packaging line, blow-off air knives and cooling jets run at low setpoints. This low-pressure GFR unit filters the supply and holds a gentle, stable regulated pressure, while the check valve keeps the setting if the main supply dips between machine cycles.
A conveyor system with pneumatic diverters, stoppers and lifters draws air from a 1 in header. This filter regulator cleans the header supply, regulates it for the whole actuator bank, and the psi gauge lets maintenance read the line setting at a glance.
Process and laboratory skids with air-operated valves and sample-handling cylinders need clean air at a low, steady pressure. This unit provides 40 um filtration and low-pressure regulation at the skid inlet, with the check valve preventing backflow into the supply header.
Size 600 with a 1 in port sits at the top of the GFR range, so start there when the line feeds multiple actuators or high-demand equipment and verify the flow curve against your consumption before ordering. This unit is the low-pressure type (code L): choose it when the working setpoint sits at the low end of the scale, and ask us to confirm the exact adjustment range from the datasheet, since it is not published as a single figure. The differential-pressure drain is the default and suits steady-flow lines; if the line stops often, ask about automatic or manual drain variants. Filtration is the standard 40 um element, fine enough for general actuator and valve supply - specify 5 um (code W) only where finer protection is required. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives. Thread is NPT on this unit (PT is the AirTAC standard, G is also orderable), and code J means no mounting bracket is included - add one if the unit will not be line-supported. The fitted check valve (code K) holds downstream pressure if the upstream supply drops.
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 flow for the GFR series as performance curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air consumption, and we will confirm the sizing from the datasheet curves before you order.
Code L in the model marks the low-pressure regulator type, intended for applications where the working setpoint sits at the low end of the scale; its exact adjustment range is not published as a single figure, so we confirm it from the datasheet on request. Code K means a reverse/check valve is fitted, which holds the downstream pressure if the upstream supply is interrupted.
