The AirTAC GFR60025F1TK 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 GFR60025F1TK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 600 unit with a 1 in NPT port, 40 um standard filtration, a differential-pressure drain, and an aluminium alloy bowl (size 600 bowls are aluminium alloy). It is the standard regulator type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a fitted embedded square gauge scaled in MPa, a reverse/check valve, and a mounting bracket included.
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, and options include 5 um filtration (code W), automatic or manual drains, psi or bar gauge scales, an external round gauge, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so we 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 0.15 - 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.

Point-of-use conditioning for a CNC machining cell: clean, moisture-reduced air at a set pressure feeding tool clamps, tool changers and pneumatic actuators, with the gauge giving the operator a local pressure reading.
Conditioning the air feeding conveyor diverters, stoppers and packaging cylinders on a bottling or carton line, holding a stable regulated pressure so cylinder stroke timing stays repeatable through the shift.
A filter regulator at the drop of an automotive assembly station, protecting air tools and clamping fixtures from water and scale in the shop main while letting each station run at its own set pressure.
Start with the port and size step: the GFR600 carries a 1 in port, and larger sizes move more air - match the size to the flow your line needs rather than to the pipe alone. Choose the drain: differential-pressure (this unit, drains automatically as the pressure differential rises), automatic (A), or manual (M). Choose the filter grade: 40 um standard, or 5 um (W) where finer protection is needed. Gauge options are the embedded square gauge (this unit, MPa scale) or an external round gauge, with MPa, psi or bar scales. Thread is PT as standard; G (BSPP) and NPT (this unit) are catalogue options to order. A bracket is included; J deletes it.
Flow for this family is published as curves, not a single rated number, so we do not quote a rated flow figure. Ask us to confirm sizing against your application and the datasheet 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 rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the flow figures from the datasheet on request before you order.
This unit has the differential-pressure drain (blank code), which discharges collected condensate automatically when the pressure differential across the element rises - no operator action needed. If you prefer a set schedule, the M code gives a manual drain; the A code gives an automatic float drain. All three are catalogue options on the GFR600.
