The AirTAC GFR600C20ALJF2WT AirTAC Filter Regulator NPT3/4 5 um 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 GFR600C20ALJF2WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is built with 3/4 in NPT ports, a 5 um filter element (code W) for finer particle capture than the standard 40 um grade, and an automatic drain that bleeds collected condensate from the bowl without manual attention. The regulator is the low-pressure type and carries an embedded square gauge reading in psi. At size 600 the bowl is aluminium alloy, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of port sizes, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options, and bracket or no-bracket mounting. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures for your application on request.

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.

Feeds the clamp and fixture cylinders on a machining centre, holding the air supply clean at a set low pressure so workholding stays consistent through the shift.
Conditions air for the stop gates and diverters on a carton packaging conveyor, with the automatic drain handling condensate on a line that runs without an operator at the unit.
Prepares instrument air for a laboratory or pilot plant skid, where the 5 um element protects sensitive pneumatic controls and the low-pressure regulator suits delicate actuation.
Size and port set the mechanical envelope: this is the largest GFR size (600) with 3/4 in NPT ports, the step to take when your line plumbing is 3/4 in and your air demand sits above what smaller sizes serve - we can confirm the flow curve against your consumption before you order. Filtration is 5 um here (code W) instead of the standard 40 um; choose the finer grade when downstream valves and cylinders need cleaner air. The automatic drain suits unattended installations; manual and differential-pressure drains are the alternatives in this family. The square gauge reads psi; MPa and bar scales are available. PT is the standard thread across the series, with G and NPT as orderable options, and a mounting bracket can be added if this no-bracket unit needs one. Because published flow is a set of curves rather than one rated number, send us your application details 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 flow for the GFR series as performance curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your working pressure and air consumption and we will confirm the relevant curve and datasheet figures for this 3/4 in size-600 unit on request.
The A in the code selects the automatic drain: collected condensate is expelled from the aluminium alloy bowl on its own, which suits installations that are not checked daily; manual and differential-pressure drains are the other GFR options. The W code selects the 5 um element instead of the standard 40 um, giving finer particle removal for downstream valves and actuators.
