The AirTAC GFR600C25LC3T AirTAC Filter Regulator NPT1 Low Pressure 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 GFR600C25LC3T is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit has a 1 in NPT port and is the low-pressure type, so it suits circuits that run at reduced regulated pressure rather than full line pressure. Filtration is the standard 40 um element, water is carried off through the differential-pressure drain, and the metal bowl on this size is aluminium alloy. A round gauge scaled in bar is fitted so operators can read and set the downstream pressure, and the unit includes a mounting bracket. No reverse (check) valve is fitted.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is ordered with choices of drain type, 40 um or 5 um filtration, gauge style and scale, thread form (PT standard, G or NPT to order) and bracket. Because AirTAC publishes flow only as curves rather than a single rated figure, we confirm the datasheet and flow 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.

Installed at the point where the 1 in main air drop feeds a process line that operates below full line pressure, the filter regulator removes water and pipe scale and holds the reduced working pressure the line was set up for.
Mounted on the air preparation panel of a packaging machine, it cleans the shop air feeding cylinders and actuators and regulates it to the machine's specified supply pressure, with the bar gauge giving operators a visible setpoint.
Placed ahead of a clamping or holding fixture circuit, it filters the incoming compressed air and lets a technician dial in the clamping pressure on the fitted bar gauge, protecting the fixture from over-pressure events.
Start with the size and port: 600 is the largest GFR frame, and the 1 in NPT port here should match your air drop so the frame is not throttled by smaller pipework. Drain choice matters: differential-pressure (this unit) bleeds condensate as flow-driven pressure drop builds, while automatic and manual variants are available in the family. Filtration is 40 um standard; choose the W code for 5 um where downstream equipment needs finer protection. Gauge options are an embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit carries a round gauge in bar. Thread is PT as standard, with G (BSPP) and NPT as order options; the T in this code selects NPT. Bracket included on this unit; J codes delete it.
On sizing: AirTAC publishes flow for this family as curves, not a single rated number, and the low-pressure type's regulation range is not stated as a single published figure either. Ask us to confirm the datasheet and flow curves against your required flow and regulated pressure 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 does not publish a single rated flow figure for this unit; flow is given only as curves in the datasheet. Tell us your required flow and operating pressures and we will confirm the datasheet and flow curves for the GFR600 against your application on request.
The L in the code marks this as the low-pressure regulator variant rather than the standard type, intended for circuits regulated well below full line pressure. The exact regulation range for the low-pressure type is not published as a single figure, so we confirm it from the datasheet on request. Note also the T code: this unit is ordered with NPT threads, while PT is the standard thread and G (BSPP) is the other order option.
