AirTAC GFR300-08 Filter Regulator (GFR30008MF1)
The AirTAC AirTAC GFR300-08 Filter Regulator (GFR30008MF1) 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 PT1/4" 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 (GFR30008MF1)
The AirTAC GFR30008MF1 is a G-series filter regulator: it strips water and particulate from compressed air and regulates downstream pressure in one unit. This configuration is the 300 size with a PT1/4 (Rc 1/4) port, the standard 40 um filter element, a manual drain bowl, and an embedded square gauge with an MPa scale. The polycarbonate bowl is standard on the 300 frame and a mounting bracket is included.
This is a genuine AirTAC part. The G-series covers sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and options for drain type, element grade, gauge and thread, so one family can serve the whole plant. Flow appears in the catalogue as curves rather than one rated figure - ask us and we will confirm 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 0.05 - 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.
Model Code: AirTAC GFR300-08 Filter Regulator (GFR30008MF1)
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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 GFR300-08 Filter Regulator (GFR30008MF1) Is Used
Plant air drop stations
The standard conditioning point at machine drops on a factory floor: knock out water and 40 um-plus dirt, hold a fixed secondary pressure, and let the embedded MPa gauge show line status without opening a panel.
Conveyor air-knife and jet circuits
Supplies steady regulated air to jet nozzles and air-knife strips that clear product or debris on conveyor lines, with manual bowl draining tied into routine line cleaning.
Pneumatic fixture clamping benches
Conditions and regulates air on weld and assembly fixture benches where clamps, swing cylinders and sensors run off a 1/4 inch circuit and the setter checks pressure on the square gauge.
Is the AirTAC GFR300-08 Filter Regulator (GFR30008MF1) the Right Unit?
Use the 300 size / 1/4 inch PT port where you need more headroom than the 200 frame without stepping up to 1/2 inch. The manual drain (M) is the right choice when the unit sits where an operator can bleed it on a routine walk; pick automatic or differential-pressure drains for hard-to-reach spots. The standard 40 um element suits general plant air; specify W for 5 um where fine protection is needed.
The square gauge here reads in MPa; round gauges and psi/bar scales are available elsewhere in the range. Thread is PT (Rc) as standard, with G (BSPP) and NPT as orderable options. Because flow is published as curves and not a single rating, ask us to confirm the curve against your flow demand 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC GFR300-08 Filter Regulator (GFR30008MF1) FAQ
AirTAC publishes this series' flow as curves, not a single rated figure, so we do not quote one number. Send us your inlet pressure and target flow and we will confirm the datasheet curve data for this 300 size before you order.
Reading the suffix: M is the manual drain (you empty the bowl by hand, and the regulator range is 0.05-0.9 MPa / 7-130 psi on this version), F is the embedded square gauge, and 1 is the MPa scale. If you prefer psi or bar, or a round external gauge, other suffixes in the same series cover those choices.
