The AirTAC GFR600C25ALJC2WT 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 GFR600C25ALJC2WT is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body, sized for a 1 in NPT port at the large 600 frame. This configuration carries the 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade, an automatic drain that ejects collected condensate without manual attention, and the low-pressure regulator type with a round gauge reading in psi. The bowl on this 600-size unit is aluminium alloy, and no mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and is offered with a choice of drain type, filter grade, gauge style and scale, thread form (PT standard, with G and NPT as order options), bracket and check-valve variants. Maximum working (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 rated figure, so ask us to confirm the datasheet and sizing 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. 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.

Installed at the air drop feeding a CNC machining cell, this unit filters water and swarf-carrying particulate down to 5 um and holds a steady low-pressure supply to the machine's directional valves and clamps, with the automatic drain keeping condensate off the shop floor.
Mounted ahead of the cylinder bank on a bottling-line conveyor section, it cleans the shop air to 5 um and regulates it to the pressure the stopper and pusher cylinders were designed for, while the round psi gauge lets a technician verify setting at a glance.
Used on a laboratory pneumatic test rig that needs a gentle, stable supply rather than full line pressure, the low-pressure regulator type trims the feed to the sensitive range the rig requires and the 5 um element protects meters and fittings from water and fine dirt.
Step through the real, decodable choices before ordering. Size and port: 200/300/400/600 with ports from 1/8 in to 1 in - match the frame to the pipe and the air demand of the circuit. Drain type: differential-pressure (default), automatic (this unit) or manual. Filter grade: 40 um standard or 5 um with the W code (this unit). Gauge: embedded square gauge standard or external round gauge, with MPa, psi or bar scales - this code carries a round psi gauge. Thread: PT is the standard, with G (BSPP) and NPT as catalogue options to order. Bracket: included by default, omitted with the J code (this unit).
One honest routing note: AirTAC publishes flow for this family as curves, not as a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm sizing against the datasheet curves 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 we do not quote a rated flow, Cv or SCFM number. Send us your application - line pressure, downstream demand and acceptable pressure drop - and we will confirm the sizing from the datasheet curves on request before you order.
The trailing W in the code selects the optional 5 um filter element in place of the 40 um standard grade. The finer element removes smaller water droplets and particulate, which suits paint and instrumentation work and protects sensitive valves; the standard 40 um grade remains available on other GFR codes if coarser general-purpose filtration is sufficient.
