The AirTAC GFR600C25MLF1TK AirTAC Filter Regulator NPT 1 in 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 GFR600C25MLF1TK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit carries a 1 in NPT port, a manual drain on the metal bowl, the standard 40 um filter element, a low-pressure regulator fitted with an embedded square MPa gauge, a reverse (check) valve, and a mounting bracket. The aluminium alloy bowl suits this largest frame in the range.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, and options that include automatic, manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, G or NPT threads in place of the PT standard, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm the 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. 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.

Feeding filtered, pressure-controlled air to spray guns and air-driven agitators on an industrial paint line, where the low-pressure regulator holds a gentle downstream setting and the manual drain lets operators bleed off collected water at the start of each shift.
Conditioning the 1 in main feeding cylinders and grippers on a carton-forming packaging line, with the 40 um element stopping pipe scale from reaching the directional valves and the built-in check valve holding the downstream circuit if the supply dips.
Supplying clean, regulated air to large pneumatically actuated ball and butterfly valves on a process skid, where the embedded square MPa gauge gives operators a local setpoint readout right at the panel and the metal bowl stands up to the plant environment.
Choose the size by the port and flow step: 200, 300, 400 and 600 map to ports from 1/8 in up to 1 in, and larger frames carry more flow - we confirm exact figures from the datasheet curves on request. Drain types are differential-pressure (the default), automatic (code A) and manual (code M), which this unit carries. Filter grade is 40 um standard or 5 um with code W. Gauges: the embedded square gauge is standard with MPa, psi or bar scales, and an external round gauge is optional. Threads: PT is the standard; G (BSPP) and NPT are ordered as code suffixes, as on this unit. Brackets are included unless the J (no bracket) code is specified. Because flow is published as curves, not a single rating, send us your flow and pressure requirements 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 GFR flow as curves rather than a single rated figure, so we do not quote one number here. Send us your inlet pressure, set pressure and required flow, and we will confirm the sizing against the datasheet curves on request.
The M in the code selects a manual drain: an operator opens the drain to expel collected water, instead of relying on the automatic (A) or differential-pressure (blank) drain options. The L selects the low-pressure regulator type; the exact adjustment range for this type is not published in the data we hold, so we confirm it on request. The F1 code adds the embedded square gauge with an MPa scale, and the K adds the reverse (check) valve.
