The AirTAC GFR60025MLF2T 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 PT1" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025MLF2T is a size-600 GFR filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built around a 1 in NPT port, the largest port in the G-series range, for high-flow supply lines. It carries the standard 40 um filter element, a manual drain on the bowl, and the low-pressure regulator type, so it suits circuits that must be held at reduced pressure rather than near line pressure. The embedded square gauge reads in psi, and the bowl on this size 600 unit is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of thread (PT standard, G and NPT as options), drain type (manual, automatic or differential-pressure), filter grade (40 um standard, 5 um optional), gauge scale and low-pressure type. Flow is published as curves rather than a single rating, so we confirm flow and datasheet 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. 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 at the take-off of a 1 in compressed-air main feeding a production hall, it removes water and pipe scale from the standard 40 um element and holds the downstream header at a reduced, low-pressure setting read on the psi gauge.
On a process skid where big pneumatic actuators and pilot solenoid valves need steady reduced pressure, the low-pressure regulator holds the pilot line stable while the filter keeps rust and moisture out of the valve seats.
Mounted ahead of the cylinder bank and air motors that drive a bottling-line conveyor, it filters the shop air and regulates it to the pressure the drive was set up for, with the manual drain emptied during scheduled line cleaning.
Start with the port step: this unit is the size-600 frame with a 1 in NPT port, the top of the G-series range, so match it to the branch diameter and the air demand of the circuit; if the line is smaller, a 400 or 300 frame with a smaller port may be the better fit. Choose the drain: this code has a manual drain (M), which means someone drains the bowl on a routine; automatic or differential-pressure drains are available on other codes if the unit is hard to reach. The filter grade here is the standard 40 um element; specify the W code for the 5 um grade if downstream valves or instruments need finer filtration. The low-pressure type (L) regulator is intended for circuits held well below normal line pressure; the exact adjustment range for this type is not published in the standard table, so ask us to confirm it against your setpoint. The gauge on this code is the embedded square type reading in psi (scale 2); MPa and bar scales and an external round gauge are alternatives. Thread is NPT on this code; PT is the standard and G is also available to order. A mounting bracket is included.
Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your application 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 publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Send us your line size and air demand and we will confirm the flow from the datasheet on request before you order.
The M in GFR60025MLF2T is the manual-drain code: collected water is released by operating the drain by hand on a routine that suits your duty. If the unit is mounted where routine access is difficult, choose a code with A (automatic drain) or no drain letter (differential-pressure drain) instead; the drain choice also affects the regulator adjustment range, so confirm the range for your drain type with us.
