The AirTAC GFR600C25MJF3WT AirTAC Filter Regulator 1 in NPT 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 See datasheet 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 GFR600C25MJF3WT is a 600-size filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration carries a 1 in NPT port for high-flow supply lines, a 5 um filter element (code W) for finer filtration than the 40 um standard, a manual drain on the bowl for scheduled blow-down, and an embedded square gauge reading in bar so the set pressure is visible at the unit. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), no reverse/check valve is fitted, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G and NPT thread options. Drain, filter grade, gauge style and scale, bracket and reverse-valve choices let you match the unit to the installation. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application before you order.

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.

Installed at a 1 in branch off the compressor receiver in a manufacturing plant, it filters carryover water and rust from the header and lets maintenance set a stable, visible working pressure for the whole drop.
Placed ahead of a bank of directional valves and cylinders on an automated line, it cleans the supply to 5 um and holds the actuator circuit at the pressure the valve manufacturer specifies, with the bar gauge readable at the unit.
Fitted into the air circuit of presses, hoists or material-handling machinery that runs large-bore supply lines, it combines water/particulate removal and pressure setting in one body, with manual drain during scheduled maintenance rounds.
Size and port set the flow capacity: the 600 series with a 1 in port is the largest step in the GFR range, so size up from 200/300/400 when your supply line and air demand call for it - and let us confirm the fit, since flow is published as curves, not a single rating. Drain type is a real choice here: this unit is manual drain, which suits attended installations with a regular blow-down routine; automatic and differential-pressure drains are available in the family if you cannot rely on manual draining. The 5 um element (code W) is the finer option over the 40 um standard - choose it when downstream equipment is sensitive to finer particles. The square gauge is fitted and reads in bar; external round gauges and MPa or psi scales are the alternatives. Thread is NPT on this unit, with PT (standard) and G available to order, and no mounting bracket is included (bracket options exist in the family).
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 GFR600 as curves, not as a single rated number, so we do not quote a figure that is not in the datasheet. Tell us your line pressure and air demand and we will confirm the sizing against the published curves on request before you order.
This unit is ordered with a manual drain (code M): condensate collects in the aluminium alloy bowl and is released when an operator opens the drain, which suits installations with a regular maintenance routine. The GFR family also offers automatic and differential-pressure drains if unattended draining is required - note the regulator adjustment range differs by drain type: 0.05-0.9 MPa (7-130 psi) with manual drain.
