The AirTAC GFR600C25LJF1WTK AirTAC Filter Regulator NPT1 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 GFR600C25LJF1WTK is a size 600 filter regulator: water and particulate removal and downstream pressure regulation combined in one body. This configuration carries a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain that bleeds condensate automatically whenever the pressure differential across the element rises, and the low-pressure regulator type (code L). It is fitted with the embedded square gauge scaled in MPa and a reverse/check valve (code K), and it ships without a mounting bracket (code J). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The bowl on this size is aluminium alloy.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, square or external round gauges scaled in MPa, psi or bar, PT (standard), G or NPT threads, and optional brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Conditions the compressed air feeding low-pressure mould-cooling and blow-air circuits: the 5 um element strips water and fine particulate, the low-pressure type holds a low setpoint, and the differential-pressure drain keeps condensate off the mould side without operator attention.
Supplies filtered, regulated air to hold-down and reject-blower jets along a high-speed bottling conveyor; the 1 in NPT connection serves the main header, and the fitted check valve holds the circuit when upstream pressure dips.
Feeds the low-pressure pulse-jet cleaning header of a dust-collector through a 5 um element, protecting the pulse valves from water and particulate while the regulator holds the header setpoint and the differential-pressure drain bleeds condensate under continuous duty.
Start with the port and size step: the 600 frame with its 1 in connection is the largest step in the GFR range, so match it against the pipe size and the flow curve of the line it feeds rather than against a single rated number. This unit is the low-pressure type (L), which is the right choice where the regulated setpoint sits well below standard working pressure; the exact regulation range for this variant is not published, so confirm it with us against your setpoint. The 5 um (W) element suits circuits that need finer particulate control than the 40 um standard; the differential-pressure drain suits lines that run continuously, since it purges condensate without operator attention. The embedded square gauge is scaled in MPa; psi or bar scales and an external round gauge are orderable options. NPT is specified here; PT (standard) and G are the other catalogue thread options. If a bracket is needed for panel or wall mounting, order the version without the J code.
Because AirTAC publishes flow as curves, not a single rating, ask us to confirm sizing from the datasheet against your application before ordering.
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 GFR series as curves, not as a single rated figure, so we do not quote a number on the page. Send us your line pressure, setpoint and expected air demand and we will confirm the sizing from the datasheet before you order.
The L code selects the low-pressure regulator type, intended for circuits regulated well below standard working pressure. The exact regulation range for this variant is not published in the catalogue, so confirm your setpoint with us and we will verify it from the datasheet. Everything else on this unit is standard GFR600: 1 in NPT port, 5 um element, differential-pressure drain, square MPa gauge and fitted check valve.
