AirTAC GFR600-25 Filter Regulator (GFR60025AC1K)
The AirTAC AirTAC GFR600-25 Filter Regulator (GFR60025AC1K) 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 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 (GFR60025AC1K)
The GFR60025AC1K is an AirTAC GFR600 filter regulator in the 600 size with 1 in G (BSPP) ports. A selects the automatic drain, which expels condensate when the air stops flowing; the element is the standard 40 um grade; C1 specifies an external round gauge on an MPa scale; and K adds a built-in reverse (check) valve that holds downstream pressure if the upstream supply drops. With automatic drainage the regulator adjusts 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), the 600-size bowl is aluminium alloy, and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in. Across the series you can order PT or NPT threads, differential-pressure or manual drains, a 5 um element, alternative gauge scales, and the unit with or without the check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and send the datasheet before you order.

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.
Model Code: AirTAC GFR600-25 Filter Regulator (GFR60025AC1K)
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

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 (GFR60025AC1K) Is Used
Power press holding circuit
Keeps regulated air on a mechanical power press counterbalance or clutch circuit; the built-in check valve holds the set pressure if the upstream supply is interrupted.
Gripper circuits that must hold
Supplies a robot gripper or clamp circuit where the part must stay gripped through a supply dip; the K check valve blocks backflow toward the regulator.
Paint line atomizing air
Conditions atomizing air ahead of spray stations on a coating line; filtration with no lubrication keeps oil out of the finish, and the check valve prevents back-surge at shutdown.
Is the AirTAC GFR600-25 Filter Regulator (GFR60025AC1K) the Right Unit?
Size steps 200, 300, 400, 600 with ports from 1/8 to 1 in; this is the 600 size at 1 in G (BSPP), and we will confirm the step against the published flow curves on request. Drain types: automatic (this unit), differential-pressure (default) and manual (opened by hand; the only drain type with the 0.05-0.9 MPa set range). Element: 40 um standard, or 5 um (W) for finer protection. Gauge: C1 is the external round gauge on an MPa scale; psi and bar scales are catalogue options. The K code fits the check valve - order the code without K where you do not need downstream pressure holding. Thread: G (BSPP) on this code; PT (standard) and NPT (T) are catalogued alternatives. Flow is published as curves, not a single rating - tell us your application and we will confirm sizing from the datasheet 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 (GFR60025AC1K) FAQ
No. AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and demand and we will confirm sizing from the datasheet on request before you order.
K fits a reverse (check) valve in the unit: air flows normally in the working direction, but downstream pressure is held if the upstream supply falls. Order the same code without the K where that holding function is not needed. The rest of the decode is unchanged: 600 size, 1 in G (BSPP) ports, automatic drain, 40 um element and round MPa gauge.
