AirTAC GFR200-08 Filter Regulator (GFR20008C1WGK)
The AirTAC AirTAC GFR200-08 Filter Regulator (GFR20008C1WGK) 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 PT1/4" 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 GFR200-08 Filter Regulator (GFR20008C1WGK)
The AirTAC GFR series combines water/particulate filtration and pressure regulation in one body. This GFR20008C1WGK is the 200 size with a G (BSPP) 1/4 inch port, a 5 um filter element (W code), the standard differential-pressure bowl drain, an external round pressure gauge on the MPa scale, and a reverse (check) valve fitted. It cleans compressed air and holds a set downstream pressure with an adjustment range of 0.15-0.9 MPa (20-130 psi); maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The G series runs from size 200 to 600 with ports from 1/8 to 1 inch; this 200 body has a PC (polycarbonate) bowl, operates from -5 to 70 C non-freezing, and comes with a mounting bracket included as standard. Flow is published as curves rather than a single rating, so we confirm datasheet and sizing 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.
Model Code: AirTAC GFR200-08 Filter Regulator (GFR20008C1WGK)
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 GFR200-08 Filter Regulator (GFR20008C1WGK) Is Used
Modular fixture control panel
Feeds a fixture clamping panel where the check valve keeps downstream settings from being disturbed by backflow, with filtered and regulated air at a 1/4 inch G port.
Bottling line actuator supply
Conditions the air feeding valve actuators on a small bottling line, removing compressor water and holding a stable setting for repeatable valve stroke timing.
Lab automation air prep
Provides clean, regulated air to benchtop laboratory automation using fine pneumatic components, protected by the 5 um element.
Is the AirTAC GFR200-08 Filter Regulator (GFR20008C1WGK) the Right Unit?
Sizing starts at the port: the 200 size steps up from the 1/8 inch 06 port to this 1/4 inch 08 port, while larger 300/400/600 bodies carry bigger ports and more flow - match the step to your demand. The K code adds a reverse/check valve, useful where backflow through the unit must be prevented. If condensate load is light, the differential-pressure drain (standard here) works set-and-forget; choose the M manual or A automatic drain code where service access or unattended draining matters. The 5 um element (W) suits finer instrument circuits; the standard element is 40 um.
This version carries an external round gauge on the MPa scale and G (BSPP) thread; NPT is available as a catalogue option and PT is the series standard. A J-code variant omits the bracket. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC GFR200-08 Filter Regulator (GFR20008C1WGK) FAQ
AirTAC publishes G-series flow as pressure-drop curves rather than a single rated figure, so we do not quote a number here. Tell us your demand and line pressure and we will confirm the flow and sizing from the datasheet on request.
The G makes the 1/4 inch port G (BSPP) parallel thread instead of the PT standard, so it mates with BSPP fittings without extra conversion. The K fits a reverse/check valve in the unit, so air cannot flow backwards through it - order the code without K if backflow is not a concern.
