The AirTAC GFR60025C3TK 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 PT1" 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 GFR60025C3TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 600 unit is built with a 1 in NPT port, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough. Because it is the 600 size, the bowl is aluminium alloy. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and the C3 code specifies the external round pressure gauge with a bar scale. A reverse/check valve (K) is fitted, holding downstream pressure if the upstream supply is lost.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um (W) filtration, automatic or manual drain variants, gauge and scale choices, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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.

Filtered and regulated air feeds spray booths and air-assisted applicators, where the 40 um element strips water and pipe scale and the regulator holds a steady set pressure for consistent finish work.
On a corrugated box line, this unit conditions and regulates the supply to sealing and flap-fold cylinders, with the check valve holding the downstream circuit if the upstream supply drops.
Upstream of a bank of pneumatic divert and fill valves, the unit delivers clean, regulated air at a stable set point, with the 1 in NPT port matching the main manifold feed.
Start with the port and size: this unit steps up to 1 in NPT on the 600 frame, the largest in the GFR range, so match it to the pipe diameter and air demand of the circuit. Choose the drain to suit access: this configuration uses the differential-pressure drain (default); automatic (A) or manual (M) drains can be ordered instead. Filtration is 40 um as standard, with a 5 um element available under code W where finer protection is needed. The gauge here is the external round type reading in bar; embedded square gauges and MPa, psi or bar scales are the other options. Thread is NPT on this unit; PT is the standard GFR thread and G (BSPP) is also a catalogue option. A mounting bracket is included. 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. The reflux valve permits reverse flow 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 figure, so we do not quote a number here. Tell us your line pressure, set pressure and air demand and we will confirm the flow from the datasheet and check the sizing for your application before you order.
C specifies the external round pressure gauge and 3 specifies the bar scale. The alternative is the embedded square gauge (F) with MPa, psi or bar scales, ordered by the matching scale digit in the code.
