AirTAC GFR600-25 Filter Regulator (GFR60025AC1WK)
The AirTAC AirTAC GFR600-25 Filter Regulator (GFR60025AC1WK) is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a automatic 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 (GFR60025AC1WK)
The AirTAC GFR series combines filtration and pressure regulation in one body: a drain bowl strips water and particulate from the compressed air, then an integrated regulator sets the downstream pressure. This 600-size unit carries a 1 in PT port, an automatic drain, a 5 um element for finer filtration than the standard 40 um grade, an external round gauge scaled in MPa, and the K option: a reverse (check) valve fitted in the body. No lubricator is included.
This is a genuine AirTAC part. The G-series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, G (BSPP) and NPT thread options, manual or differential-pressure drains, standard or low-pressure regulator types, and gauge choices. Maximum working pressure is 1.0 MPa (145 psi); with the automatic drain fitted, the regulator adjusts from 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing. Because rated flow is published only as curves, we confirm flow and full datasheet figures 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.

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 (GFR60025AC1WK) Is Used
Pneumatic press feed with backflow protection
Filters and regulates the 1 in air feed to a pneumatic forming press, with the fitted check valve holding the set circuit conditions when upstream supply pressure dips or the line is shut down.
Robotic weld cell clamp supply
Conditions plant air feeding weld-gun and fixture clamps in a robotic cell, delivering cleaned, regulated air at the cell boundary while the check valve guards the circuit against reverse flow.
Main distribution header regulation
Installed on a branch of a factory distribution header, it cleans the air, sets the branch pressure, and uses the automatic drain and check valve combination where the branch cannot be attended or bled back.
Is the AirTAC GFR600-25 Filter Regulator (GFR60025AC1WK) the Right Unit?
At 600 size with a 1 in PT port this is the largest frame in the G-series; drop to 400, 300 or 200 if your port and duty are smaller - we will check your demand against the published flow curves before you order. The trailing K adds a reverse (check) valve, useful where backflow must be prevented at the unit; omit K if you do not need it. The automatic drain removes condensate unattended, while manual (M) and differential-pressure (blank) drains are the other choices. The 5 um element is finer than the standard 40 um grade. Gauge scale is MPa here, with psi (2) and bar (3) versions available. Thread is PT as standard; G (BSPP) and NPT are order options, and a bracket is included (code J deletes it).
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 (GFR60025AC1WK) FAQ
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so there is no honest single number to quote. Share your application and we will confirm the flow and full datasheet figures on request before you order.
K specifies that a reverse (check) valve is fitted in the unit, preventing backflow through the filter regulator. The same unit without K is GFR60025AC1W, identical in every other respect: 1 in PT port, automatic drain, 5 um element and MPa round gauge.
