The AirTAC GFR600-25G AirTAC Filter Regulator 1 in G Thread 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 GFR600-25G is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with a 1 in G thread, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough. The aluminium alloy bowl suits the larger 600 frame, the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and the round external gauge is supplied on a psi scale. A reverse/check valve is fitted, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options include a 5 um element (code W), automatic or manual drains, different gauge scales, and PT or NPT threads in place of G. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

Clean, regulated air at each paint-line drop keeps spray guns and air-assist equipment supplied with dried air at a set working pressure, with condensate bled off by the differential-pressure drain.
A single point of filtration and regulation ahead of the palletizer's cylinder and gripper circuits holds a stable working pressure for clamp-and-place motions on a 1 in main.
Mounted on the shop-air main feeding a CNC cell, the filter regulator protects valves and actuators from water and scale while holding the set pressure the machine's air circuits were designed around.
Start with the port and frame: the 600 size with a 1 in connection sits at the top of the GFR range, so match it to the line size and required air demand of your installation. Choose the drain next - this unit uses the differential-pressure drain, while automatic (code A) and manual (code M) versions are available if your maintenance routine suits them better. The 40 um element is standard here; specify the 5 um W grade if downstream equipment needs finer filtration. The round gauge on this unit reads in psi; MPa and bar scales are also available, and an embedded square gauge is the standard alternative. Thread can be ordered as PT or NPT instead of G, and a mounting bracket can be added (this unit is supplied without one). Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before you order.
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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, working pressure and expected air demand, and we will confirm the correct size from the datasheet on request.
This unit's differential-pressure drain discharges collected condensate automatically when the pressure differential across the bowl rises, so no routine manual draining is needed. If your application calls for a positive timed blowdown or a fully manual drain, the same 600-size unit can be ordered with automatic (code A) or manual (code M) drain instead.
