The AirTAC GFR60025LC1WT AirTAC Filter Regulator 1in NPT 5um is a genuine G-series filter regulator: water separation, 5 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 GFR600 combines water and particulate filtration with pressure regulation in a single body, so one component cleans the air and sets the working pressure downstream. This configuration is the size 600 unit with a 1 in NPT port, built as the low-pressure type for circuits that run below standard regulator settings. It carries the 5 um filter element (code W) for finer protection of downstream valves and cylinders, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an aluminium alloy bowl, which is the bowl material used at size 600. A round external gauge on the MPa scale is fitted, the mounting bracket is included, and no reverse/check valve is fitted. 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 filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is available with manual or automatic drains, the standard 40 um or fine 5 um element, square or round gauges on MPa, psi or bar scales, G, NPT or PT threads, and bracket options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the flow and datasheet figures for your application before ordering.

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.

On a palletizer or stretch-wrapping line running at reduced circuit pressure, this 1 in filter regulator cleans the shop air to 5 um and holds a stable low setpoint for the grippers and wrapper actuators, with the differential-pressure drain handling condensate on continuously flowing lines.
As the main air-preparation point feeding pushers, diverters and stop gates along a packaging conveyor, the GFR600 removes water and fine particles that would score valve spools, while the low-pressure type regulation suits conveyor actuator circuits that run below standard plant pressure.
On a test rig or pilot line where components are cycled at controlled sub-standard pressures, the low-pressure regulator type gives the fine setting the bench needs, the 5 um element protects the instrumented cylinders, and the round MPa gauge gives a clear direct pressure readout.
Start with the port step: this unit is size 600 with a 1 in NPT port, the largest in the GFR range, so match it to the line size and the flow your circuit needs - we can confirm the published flow curves against your demand before you order. The drain here is differential-pressure, the default, which purges condensate in response to flow; if your compressor runs intermittently or the unit sits upstream of a closed valve, ask about the automatic (A) or manual (M) drain variants instead. The 5 um element (W) is the finer choice for sensitive valves and actuators; the standard element is 40 um. The gauge fitted is the external round type on the MPa scale, with psi or bar scales and the embedded square gauge available as alternatives. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also an order option. The mounting bracket is included in this configuration.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, and the exact regulation range of the low-pressure (L) type is not stated in the material we hold. Tell us your line pressure and flow demand and we will confirm the figures from the datasheet before you commit.
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 rather than a single rated figure, so we do not quote one number for this unit. Tell us your line pressure and the air demand of your circuit and we will confirm the flow figures from the datasheet for this exact 1 in NPT, low-pressure configuration before you order.
The L in the code marks this as the low-pressure type of the GFR regulator, intended for circuits that run below the settings of the standard version. The exact adjustment range of the low-pressure type is not published in the material we hold, so ask us to confirm it from the datasheet; the standard GFR range and the maximum inlet pressure of 1.0 MPa (145 psi) still apply to the body.
