The AirTAC GFR60025MF3WTK AirTAC Filter Regulator 1 in NPT, 5 um 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 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 GFR60025MF3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is built around a 1 in NPT1 port for high-flow main lines, a manual drain bowl in aluminium alloy (the 600 size uses an aluminium alloy bowl), a fine 5 um filter element, a standard regulator covering 0.05-0.9 MPa (7-130 psi), an embedded square gauge scaled in bar, and a built-in reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Mounting bracket included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, plus options you can order: PT (standard), G or NPT thread; differential-pressure, automatic or manual drain; 40 um standard or 5 um filtration; gauge scale in MPa, psi or bar; and a low-pressure regulator type. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.

Dropping off a 1 in shop-air header to feed a packaging hall: the GFR600 filters bulk water and scale out of the main supply, regulates the header pressure the lines run at, and the check valve holds the downstream circuit if the main is shut off.
Feeding a CNC machining cell where tool changers, clamps and air blasts need clean, steady air: the 5 um element protects directional valves and cylinders from particulate, while the regulator keeps clamp force consistent between cycles.
Supplying the valve manifold on an automated palletising line: the filter-regulator conditions the air before the FRL-fed control valves, the bar-scaled gauge gives operators a set point to check at a glance, and the manual drain suits a scheduled maintenance round.
Size and port are the first decision: the 600 frame with its 1 in NPT1 port suits plant air headers and high-consumption lines, while smaller GFR sizes cover lighter duties - match the size step to the flow your line actually needs. This unit carries a manual drain, so plan a walk-round drain routine; choose automatic drain if the bowl is hard to reach. The 5 um element here is the finer option versus the 40 um standard - keep 5 um where downstream valves and instruments are sensitive, 40 um for general protection. The square gauge is scaled in bar; MPa or psi scales can be ordered instead. Thread is NPT here; PT is the catalogue standard and G is also available. A bracket is included for panel or wall fixing.
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a rated flow figure. Send us your application and we will confirm the sizing against the datasheet curves on request.
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, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure, downstream demand and port size, and we will confirm the sizing against the datasheet curves on request before you order.
This configuration is coded M for a manual drain: the bowl is drained by hand, which suits installations covered by a regular maintenance round. If the bowl sits where nobody walks, order the automatic-drain (A) version instead; the differential-pressure drain is the catalogue default. Note the manual-drain inlet range differs from the other drain types, so confirm the detail with us for your pressure conditions.
