The AirTAC GFR600C25F3TK 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 GFR600C25F3TK is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This 600-size unit is threaded 1 in NPT, carries a 40 um filter element, drains condensate by differential pressure, and includes the embedded square gauge scaled in bar. The K in the code adds a reverse (check) valve, and the standard regulator covers a 0.15-0.9 MPa (20-130 psi) setting range at up to 1.0 MPa (145 psi) inlet. Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of 40 um or 5 um (W) filtration, differential-pressure, automatic or manual drains, gauge scale and thread options, and bracket or no-bracket builds. At size 600 the bowl is aluminium alloy. Flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet 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 a 1 in plant air ring downstream of the receiver, this filter regulator cleans the header supply and holds a stable setpoint for the whole shop floor.
Supplying filtered, regulated air to the cylinder banks on a carton-forming and sealing conveyor, with the check valve helping hold the circuit if upstream pressure dips.
Providing clean, regulated instrument air to positioners and pilot valves on a process skid, with the bar-scaled square gauge giving a local setpoint readout.
Choose the size by port and flow demand: this 600 unit steps up to a 1 in NPT connection for high-consumption lines, while 200-400 units cover smaller ports. The decodable choices on this code are fixed: 40 um filtration (5 um is the W option), differential-pressure drain (automatic A or manual M are the alternatives), square gauge scaled in bar (MPa or psi scales are the alternatives), NPT thread (PT is the standard, G/BSPP is an order option), and the fitted reverse/check valve. A mounting bracket is included.
Because flow for this series is published as curves rather than a single rated figure, send us your working pressure and air demand 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote one number here. Tell us your working pressure and air demand and we will confirm the datasheet curve figures for this 600-size unit on request before you order.
K marks a reverse (check) valve fitted in the unit, which keeps the downstream circuit from back-feeding if upstream pressure is lost. If you do not want it, order the same 600-size filter regulator without the K suffix.
