The AirTAC GFR600C25MJNWTK AirTAC Filter Regulator NPT1 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 GFR600C25MJNWTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 1 in NPT port, a 5 um filter element (finer than the 40 um standard), a manual drain and an aluminium alloy bowl. No gauge is fitted and no mounting bracket is included; a reverse (check) valve is fitted.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, plus drain, filter-grade, gauge, thread (PT, G, NPT) and bracket options. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) on this manual-drain version, and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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. 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.

Filtering and regulating the compressed air feeding paint spray booths, where 5 um filtration and a stable set pressure protect the finishing process from water and debris.
Supplying filtered, regulated air to clamping fixtures on a machining centre, with the fitted check valve helping hold the downstream circuit if supply pressure drops.
Regulating air to the cylinders and grippers on a packaging conveyor, with the 1 in NPT port suiting a main air drop feeding multiple actuators along the line.
Every choice in this family is decodable from the code. Step through sizes 200/300/400/600 and ports 1/8 to 1 in to match the flow your line needs - the larger the size, the larger the port and flow capacity. Choose the drain: manual (this unit), automatic, or differential-pressure (the default). Choose the filter grade: 40 um standard or 5 um with code W (this unit is 5 um). Decide on a gauge - none is fitted here; the options are an embedded square gauge or an external round gauge with MPa, psi or bar scales - and the thread: PT is the standard, with G (BSPP) and NPT as order options. Brackets are optional. Flow is published as curves, not a single rating, so 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 this series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow figures from the datasheet on request.
This unit is coded M for a manual drain: the bowl is drained by hand on a routine basis. The family also offers automatic and differential-pressure (default) drains. Note the regulation range differs: 0.05-0.9 MPa (7-130 psi) with a manual drain versus 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains.
