The AirTAC GFR60025LC3TK AirTAC Filter Regulator 1 in NPT 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 PT1" 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 GFR60025LC3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the 1 in NPT port version in the low-pressure type, fitted with a round external gauge scaled in bar, a built-in reverse/check valve, and a mounting bracket. The 40 um standard filter element handles general-purpose air preparation, and the differential-pressure drain bleeds collected condensate automatically as the pressure differential across the bowl rises - no daily manual draining on lightly loaded lines. Because this is the 600 size, the bowl is aluminium alloy rather than polycarbonate. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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, PT as the standard thread and G or NPT as order options, plus a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, embedded square or external round gauges with MPa, psi or bar scales, and a low-pressure (L) type. 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 a 1 in air drop that supplies the manifold controlling fill, capping and reject valves, with the check valve holding downstream pressure if the main supply dips and the bar gauge giving operators a direct line-pressure readout.
Sits at the head of the frame's air supply where the process runs at reduced pressure, filtering line water and particulate before the machine's pneumatic thread-tension and doffing circuits.
Conditions and regulates the air feeding clamp cylinders that press cartons against the belt, with the differential-pressure drain keeping condensate out of the clamp circuit on a long production shift.
Start with the port step: this unit is the 1 in NPT version of the size-600 body, the largest in the GFR range - move down to 300/400 sizes with 3/8 to 1/2 in ports when your line does not need the 1 in connection. Choose the drain to match maintenance reality: differential-pressure (this unit) drains on its own as condensate builds, automatic (A) dumps the bowl on a cycle, and manual (M) needs someone to open it. Filtration is 40 um standard here; specify the W code for 5 um if downstream valves or cylinders need finer protection. The round gauge on this configuration reads in bar; square embedded gauges and MPa or psi scales are available. PT is the standard thread, with G and NPT as catalogue options - order the suffix you need. A bracket is included; J codes omit it. This is the low-pressure (L) type, so confirm its regulation range against your set pressure before ordering - and since flow is published as curves, not a single rating, ask us to check the curve against your required flow.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves, not as a single rated number, so we do not quote a rated flow figure. Tell us your working flow and set pressure and we will confirm the datasheet curve for this 1 in size-600 unit before you order.
L marks the low-pressure type of regulator, intended for applications that run at reduced set pressures - confirm the exact range with us for your setpoint. This unit also has a differential-pressure drain (no drain letter in the code): condensate collected in the aluminium bowl is expelled automatically as the differential across the bowl rises, with no manual draining needed.
