The AirTAC GFR600C25LJC3T 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 GFR600C25LJC3T is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 600 unit is built around a 1 in NPT port and is the low-pressure (L) type, so it suits circuits that run below standard line pressure. Filtration is the standard 40 um element, the bowl drains by the differential-pressure method, and the bowl is aluminium alloy as used at size 600. A round pressure gauge scaled in bar is fitted; no mounting bracket and no reverse/check valve are included in this configuration. Operating temperature is -5 to 70 C (non-freezing) and maximum inlet pressure is 1.0 MPa (145 psi).
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 catalogue options include automatic or manual drains, a 5 um (W) element, embedded square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and mounting brackets. Flow is published as curves rather than a single rated figure, 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. 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.

Feeding the pneumatic cylinders and grippers on a carton-forming packaging line: the filter stage strips water and swarf carried in shop air, while the low-pressure regulator holds a steady reduced setpoint so case sealers and pushers stroke consistently.
Supplying air to clamp and hold-down cylinders on a machining fixture. The low-pressure type regulator keeps clamping force repeatable at reduced pressure, and the 40 um element protects directional valves from particulate carried in the supply.
Running air knives or blow-off nozzles above a bakery conveyor line: filtered, regulated air at a gentle low pressure clears dust and residue without disturbing product, while the differential-pressure drain handles collected condensate.
The real choices in this family are decodable from the code. Step size first: 200, 300, 400 and 600 carry increasing port sizes (1/8 in up to 1 in), so match the port to your line and let required flow - not guesswork - drive the size. Drain: differential-pressure (this unit), automatic (A) or manual (M). Filter grade: 40 um standard, 5 um with code W. Gauge: embedded square as standard, external round optional, scaled in MPa, psi or bar. Thread: PT is the catalogue standard; G (BSPP) and NPT are ordered as options - this unit is NPT. Bracket: J means none fitted. Because flow is published as curves rather than a single rated figure, send us your application and we will confirm sizing against 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 curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, setpoint and downstream demand and we will confirm the flow and full datasheet figures for this exact model on request.
L marks the low-pressure type of regulator. This unit is built for circuits that run below standard line pressure; the exact adjustment range for the low-pressure type is not published in the catalogue, so we confirm it on request. Maximum inlet pressure remains 1.0 MPa (145 psi).
