The AirTAC GFR600C25ALJNWT 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 AirTAC GFR600C25ALJNWT is a filter regulator: filtration and pressure regulation combined in one body, so a single 1 in NPT connection delivers cleaned, regulated air. This size-600 unit is built with a 5 um filter element (the finer of the two grades offered), an automatic drain that removes collected condensate without daily manual attention, and a low-pressure (L) regulator type. It is supplied without a pressure gauge and without a mounting bracket, and the aluminium alloy bowl suits the larger 600 frame.
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, and choices of drain type, 40 um or 5 um filtration, thread (PT standard; G and NPT to order), gauge and bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the 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 any datasheet figure against 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.

On a bottling line, this unit cleans and regulates the low-pressure air feeding air knives that strip rinse water from bottles ahead of filling and labelling. The 5 um element helps keep the knife slots clear, and the automatic drain copes with condensate without an operator visiting the frame each shift.
In a plastics plant, regulated low-pressure air conveys resin pellets from silo to hopper along transfer piping. This filter regulator holds the conveying pressure steady at the line inlet, filters the supply to 5 um, and its aluminium bowl and automatic drain suit a humid compressor room.
Pneumatic actuators on duct dampers and diverter gates need a steady, clean air supply. This unit filters the plant air to 5 um to help protect actuator seals and regulates it to the low pressure the actuators require, with the automatic drain keeping condensate out of the supply.
Start from the port and size: this is the 600 frame with a 1 in NPT thread, the largest step in the GFR range, so match it to the pipe diameter and the air demand of the line - if your duty sits between sizes, ask us to check the curves. Choose the drain to suit access: automatic (fitted here) suits unattended or enclosed installations, while manual and differential-pressure drains are available in the family. Filtration is 5 um on this unit (W code); 40 um is the standard grade if finer filtration is not required. The L code makes this the low-pressure regulator type - confirm the adjustment range against your set-point with us. No gauge is fitted (N code); gauge options can be confirmed on request. Thread is NPT here; PT is the standard and G (BSPP) is also an order option. No mounting bracket is included. Because flow is published as curves rather than a single rating, send us your application details and we will confirm sizing 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set-point and air demand and we will confirm the flow from the datasheet for this exact 1 in NPT, 5 um, low-pressure configuration before you order.
The L code identifies the low-pressure regulator variant of the GFR family. The exact adjustment range for this variant is not published in our data sheet extract, so we confirm it against your required set-point on request. Maximum working (inlet) pressure remains 1.0 MPa (145 psi), and the unit operates from -5 to 70 C, non-freezing.
