AirTAC GFR600-20 Filter Regulator (GFR60020C1WK)
The AirTAC AirTAC GFR600-20 Filter Regulator (GFR60020C1WK) 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 PT3/4" 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 GFR600-20 Filter Regulator (GFR60020C1WK)
The AirTAC GFR60020C1WK is a G-series filter regulator with the K option: a reverse (check) valve is fitted, so air will not back-flow through the unit when upstream pressure falls. Like every GFR, it filters and regulates in one body with no lubricator. This 600-size unit has a 3/4in PT port, a 5 um filter element, a differential-pressure drain and the external round pressure gauge with MPa scale. Maximum working pressure is 1.0 MPa (145 psi); with the differential-pressure drain the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part. G-series filter regulators run from 200 through 600 sizes, with automatic or manual drain variants, a 40 um standard element as an alternative to the 5 um grade here, other gauge and thread options (PT standard; G and NPT orderable), and the K check-valve option shown on this code. The 600-size bowl is aluminium alloy and temperature range is -5 to 70 C (non-freezing). Flow is published as curves, so we confirm the datasheet and sizing 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 GFR600-20 Filter Regulator (GFR60020C1WK) Is Used
Pneumatic press hold-down circuit
Filtering and regulating supply air to a pneumatic press, with the fitted check valve holding set pressure downstream if the shop main is shut off or loses pressure mid-cycle.
Automotive assembly drop line
Conditioning the air drop feeding torque tools and clamps at an assembly station, with the check valve preventing back-flow through the unit when neighbouring stations vent the header.
Palletiser gripper supply
Supplying filtered, regulated air to gripper and pusher cylinders on a palletising cell, where the check valve keeps the circuit from depressurising through the unit during upstream maintenance.
Is the AirTAC GFR600-20 Filter Regulator (GFR60020C1WK) the Right Unit?
Specify the K suffix when your circuit needs the built-in check valve - for example to hold downstream pressure if the supply line is vented or dropped. This code combines it with the 600 size, 3/4in PT port, 5 um element, differential-pressure drain and MPa round gauge; the same size is available without the check valve, with a 40 um element, with automatic or manual drain, and with other gauge scales. If you need NPT or G threads, order the T or G thread variants. Bracketless (J) versions exist too. Because flow for this series is published as curves rather than one rated figure, send us your flow and pressure conditions and we will confirm the datasheet match before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/4" 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 GFR600-20 Filter Regulator (GFR60020C1WK) FAQ
No - AirTAC publishes flow for this series as curves, not a single rating, so we do not state one. Share your working pressure and flow demand and we will confirm the sizing from the datasheet on request before you order.
The K suffix adds a reverse (check) valve to the filter regulator, so air cannot back-flow through it when upstream pressure drops. Everything else in the code is standard for this family: 600 size, 3/4in PT port, 5 um filter element, differential-pressure drain and an MPa round gauge - all available in other combinations from the catalogue.
