AirTAC GFR600-25 Filter Regulator (GFR60025F1K)
The AirTAC AirTAC GFR600-25 Filter Regulator (GFR60025F1K) 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.

About the AirTAC GFR600-25 Filter Regulator (GFR60025F1K)
The AirTAC GFR60025F1K is a 600-size filter regulator with a reverse (check) valve fitted, so downstream pressure is held if the upstream supply is lost, on top of the unit's normal job of filtering water and particulate and regulating pressure in one body. This version has a 1 inch PT port, the standard 40 um element, a differential-pressure drain, a square gauge with an MPa scale, and a 600 aluminium alloy bowl.
This is a genuine AirTAC part. The G-series offers 200 to 600 sizes, a 5 um (W) element, manual or automatic drain options, and G(BSPP) or NPT thread variants to order alongside the PT standard. Flow is published as curves rather than a single rating, so we confirm datasheet figures for your duty 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.

Where the AirTAC GFR600-25 Filter Regulator (GFR60025F1K) Is Used
Clamp circuits that must hold position
Feeds the safety clamp cylinders on a fixture line where the fitted check valve keeps downstream pressure in place if the shop air supply dips, holding parts clamped until power is restored.
Automated assembly cell supply
Prepares air for the pick-and-place and screwdriver actuators in an automated assembly cell, filtering the main and regulating pressure for consistent cycle behaviour.
Plant main drop preparation
Conditions a high-consumption branch off a factory compressed-air ring main, giving downstream machines one point of filtration, regulation and backflow protection.
Is the AirTAC GFR600-25 Filter Regulator (GFR60025F1K) the Right Unit?
Specify the K suffix when a drop in supply pressure would let downstream air escape - for example on circuits that must hold position during a compressor outage; without the K the unit has no check function. The 600 size with 1 inch PT port serves the largest G-series drops; choose 400 or 300 for lighter lines. Keep the 40 um element for general actuator air or move to the W (5 um) version for finer filtration.
The F1 gauge is the square style with an MPa scale; round-gauge C versions and psi or bar scales are available. The differential-pressure drain self-clears under flow, with M and A drain codes for other patterns. PT is the standard thread with G and T orderable. Flow appears only as curves, not a single rated figure, so ask us to confirm sizing before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR600-25 Filter Regulator (GFR60025F1K) FAQ
AirTAC publishes flow for the GFR600 series as curves, not as a single rated figure, so we do not quote a number here. Give us your line pressure, setpoint and air demand and we will confirm the datasheet curve data on request - noting that the fitted check valve sits in the flow path.
K means a reverse (check) valve is fitted, so the unit blocks backflow and helps hold downstream pressure if the upstream supply fails. The standard GFR60025F1 without K has no check function. Everything else in the code decodes the same: 600 size, 1 inch PT port, 40 um element, differential-pressure drain and a square gauge with an MPa scale.
