The AirTAC GFR600C25LC3TK 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 AirTAC GFR600C25LC3TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built with a 1 in NPT port, the 40 um standard filter element and a differential-pressure drain, and it is the low-pressure version of the GFR range. The aluminium alloy bowl suits this large frame, and the unit arrives with a round gauge scaled in bar, a reverse (check) valve and a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, 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 that drive filler and capper motions on a bottling line: water and particles are stripped from the shop air while the low-pressure regulator holds a steady supply pressure to the actuators.
Supplying a clamping fixture on a machining cell, where the reverse (check) valve is fitted in line and the regulator keeps clamp pressure steady from the plant air header; the 1 in NPT port suits a high-demand drop.
Filtering and regulating the air feeding flap-folders and case sealers on a packaging conveyor, with the differential-pressure drain bleeding accumulated condensate while the line runs.
Size and port are the first choice: the 600 frame with a 1 in NPT port is the largest step in the GFR range, so match it against the air demand of your circuit - we can confirm flow from the datasheet curves before you order. Drain type is decodable: this unit uses the differential-pressure drain (the family default), while automatic (A) and manual (M) versions exist. The 40 um element is standard here; specify code W for 5 um filtration. Gauge choices are the embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit carries a round gauge in bar. Thread: PT is the AirTAC standard and G (BSPP) or NPT are order options; this unit is ordered with NPT. A mounting bracket is included and the reverse (check) valve is fitted.
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 GFR flow as performance curves, not a single rated figure, so we do not quote a number. Tell us your application and we will confirm the datasheet flow figures for this size 600, 1 in NPT unit on request.
It is the thread code: this unit is supplied with a 1 in NPT port. PT is the AirTAC standard thread and G (BSPP) is also available as an order option. The rest of the code shows the low-pressure type (L), a round gauge scaled in bar (C3) and a fitted reverse valve (K).
