AirTAC GFR300-08 Filter Regulator (GFR30008MC1WK)
The AirTAC AirTAC GFR300-08 Filter Regulator (GFR30008MC1WK) 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 GFR300-08 Filter Regulator (GFR30008MC1WK)
GFR300-08MC1WK is a genuine AirTAC G-series filter regulator: filtration and pressure regulation combined in one body with a drain bowl, and no lubricator. This configuration is the 300 size with 1/4 in PT ports, a manual drain, the finer 5 um (W) filter element, an external round gauge scaled in MPa, and a reverse (check) valve fitted. It combines the cleaner-air grade with backflow protection on the same 1/4 in footprint. Regulator adjustment on this manual-drain version is 0.05-0.9 MPa (7-130 psi); maximum working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, G (BSPP) and NPT thread options, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) elements, gauge choices and an optional reverse valve. Flow is published as curves rather than a single rating, so ask us and we will confirm figures from the datasheet for your application.

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 0.05 - 0.9 MPa (7 - 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.

| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

- GFR400PT3/8" - PT1/2"
- GFR600PT3/4" - PT1"
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 GFR300-08 Filter Regulator (GFR30008MC1WK) Is Used
Robotic pick-and-place air prep
A robot cell's gripper and vacuum-generator feed needs clean, regulated air in a compact envelope. The 5 um element protects the gripper valves, and the fitted reverse valve guards the regulator on this 1/4 in branch.
Test bench instrument supply
On a pneumatic test bench, repeatability depends on a steady, clean supply to the reference instruments. This unit filters to 5 um and holds the setpoint on the bench's 1/4 in feed, with the MPa-scaled round gauge for setting.
Special machine building
Machine builders specifying one clean, regulated drop per station can standardize on this unit: 1/4 in ports, fine filtration, MPa gauge and a reverse valve in a single body simplifies the pneumatic BOM across builds.
Is the AirTAC GFR300-08 Filter Regulator (GFR30008MC1WK) the Right Unit?
This 300-size unit carries 1/4 in PT ports; choose 200, 400 or 600 if your branch uses a different port, and match the size to the flow the circuit needs. Drain is manual - automatic suits unattended lines, and the differential-pressure default suits those who want draining tied to pressure drop. The W suffix selects the 5 um element instead of the 40 um standard for finer filtration, and the K suffix adds a reverse (check) valve. The gauge is an external round type scaled in MPa; embedded square gauges and psi or bar scales are catalogue alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included. Because flow is published as curves and 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 0.05 - 0.9 MPa (7 - 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 GFR300-08 Filter Regulator (GFR30008MC1WK) FAQ
There is no single rated flow figure to quote: AirTAC publishes G-series flow as curves. Share your supply pressure, set pressure and air consumption, and we will confirm the sizing from the datasheet on request.
Manual drain means the bowl is emptied by hand, which fits lines shut down regularly for maintenance; choose the automatic drain option instead for unattended running. The K suffix adds a reverse (check) valve, so this configuration pairs the 5 um element with backflow protection in one 1/4 in unit.
