The AirTAC GFR60025LC2WT AirTAC Filter Regulator NPT1 Low Pressure 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 GFR60025LC2WT is a size 600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is built for a 1 in NPT port, carries the 5 um filter element (code W, tighter than the 40 um standard), drains condensate automatically by differential pressure, and is the low-pressure regulator type. It comes with a round pressure gauge reading in psi, an aluminium alloy bowl (standard at size 600), and a mounting bracket included.
This is a genuine AirTAC part in the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge style and scale options, and PT, G or NPT threads. Flow figures for this unit are 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. 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.

Clamping fixtures on a press line need clean, moisture-picked air held at a steady low setting so workpieces are gripped consistently. This unit filters the supply to 5 um and regulates it in one body at the 1 in main feed into the clamp manifold.
Spray and coating stations are sensitive to both water carryover and pressure drift. Mounted at the drop to the booth, this filter regulator removes particulate and condensate at 5 um and holds the low supply pressure the applicators are set up for, with the psi gauge giving operators a local reading.
Pusher and stopper cylinders along a bottling conveyor run continuously and need stable, filtered air to avoid erratic positioning. This unit conditions the branch feed to the actuator bank, its differential-pressure drain shedding condensate as the line runs.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start by matching the port and body size to the air demand of the circuit; if your flow requirement is near the top of a smaller size, step up rather than run a unit at its limit. This unit already carries the 5 um element (code W); if your application tolerates coarser 40 um filtration, the standard grade is the lower-restriction choice. Drain is differential-pressure here, which bleeds condensate as the inlet-to-outlet pressure difference builds - choose automatic drain if the unit sits where nobody checks it, or manual drain for supervised stations.
The round gauge fitted to this code reads in psi; an embedded square gauge is the standard alternative, with MPa or bar scales available. Thread is NPT on this code, ordered as an option against the PT standard, and G (BSPP) is also available. A mounting bracket is included. Flow is published as curves, not a single rated figure, so send us your flow and pressure conditions 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 figure we can quote honestly. Send us your required flow and working pressure and we will confirm the sizing against the datasheet curves before you order.
The code letters set both: C on this model orders the optional external round gauge with a psi scale instead of the standard embedded square gauge, and W orders the 5 um filter element instead of the 40 um standard. The L in the code also marks it as the low-pressure regulator type. If you want the standard square gauge, 40 um grade or standard regulator type, the same size is available under a different code.
