The AirTAC GFR60025LC2T 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 GFR60025LC2T is a size-600 filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This configuration is built around a 1 in NPT port for high-flow main air lines, a 40 um standard filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and the low-pressure regulator type for applications set well below standard line pressure. A round pressure gauge scaled in psi is fitted so the setpoint can be read directly, and the size-600 bowl is aluminium alloy. 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 from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, gauge and scale choices, and an optional reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and full datasheet details 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.

Installed on a 1 in distribution header feeding a production hall, it filters line-scale water and rust particles and holds a stable low-pressure supply to the downstream drops.
Mounted ahead of a conveyor section's cylinder bank, it removes condensate and particulate from the shop air and regulates it to the lower pressure the actuators and tubing are rated for.
Fitted at the air inlet of a CNC or press cell's clamping circuit, it cleans the incoming supply and lets the setter dial in and read a fixed low clamping pressure on the psi gauge.
Start with the port step: this unit is the size-600 frame with a 1 in NPT connection, the largest in the GFR range, so match it to your main line size and required flow. The drain here is differential-pressure, which suits lines with steady flow; choose automatic (code A) for intermittent-flow lines where condensate must still be expelled, or manual (code M) where an operator drains on schedule. Filtration is the 40 um standard element; specify 5 um (code W) if downstream valves or instruments need finer air. The round gauge on this unit reads in psi; square embedded gauges and MPa or bar scales are alternatives. Thread is NPT on this code, with PT standard and G available to order. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your application details 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 number, so there is no one flow figure we can quote for this unit. Send us your line size, pressure and expected air demand and we will confirm the sizing against the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, intended for applications set well below standard line pressure. The exact adjustment span for this variant is not published in the material we hold, so confirm your setpoint with us and we will verify suitability against the datasheet.
