Airtac GFR Filter Regulator GFR300C10NWK
The AirTAC GFR Filter Regulator GFR300C10NWK 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 See datasheet 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 GFR Filter Regulator GFR300C10NWK
GFR300C10NWK is a genuine AirTAC GFR series filter regulator: filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This configuration is size 300 with PT3/8 in ports, the 5 um (W) element instead of the standard 40 um, differential-pressure drain, no gauge fitted, and the K reverse (check) valve specified. With the differential-pressure drain, the regulated outlet is adjustable over 0.15-0.9 MPa (20-130 psi).
Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C, non-freezing; the size 300 bowl is polycarbonate (PC), while 600-size bowls are aluminium alloy. The GFR family also runs in 200/400 sizes with ports from 1/8 in to 1 in, G (BSPP) or NPT threads, automatic or manual drains, gauge options and bracket choices. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures for your application 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.

|---|---|
| C1 | Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (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. |
| (blank) | Pressure gauge fitted (blank). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

- 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 GFR Filter Regulator GFR300C10NWK Is Used
CNC machining centre air supply
Filter and regulate the shop-air feed to a CNC machine's pneumatic clamps and tool-change cylinders, with the 5 um element guarding the downstream valves.
Packaging line control valve station
Point-of-use conditioning ahead of the solenoid valve manifolds on a cartoning line, with the check valve holding the branch if the main feed dips.
Spray finishing booth regulator
Filtered, regulated air to the spray guns and atomizing air lines in a paint finishing booth, set and read at the unit on the line side.
Is the Airtac GFR Filter Regulator GFR300C10NWK the Right Unit?
Decodable choices on the GFR300: step the size (200/300/400) and port (06 = 1/8 in up to 25 = 1 in) to match your piping and demand; this code sits at 300 with 3/8 in PT ports. Drain is differential-pressure here (A = automatic, M = manual - manual widens the regulation range to 0.05-0.9 MPa / 7-130 psi); the element is the finer 5 um W grade against the 40 um standard; N means no gauge; and the trailing K adds the reverse (check) valve. Bracket is included. Flow is published as curves, not one rated figure, so ask us to confirm sizing against the GFR300 datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
Airtac GFR Filter Regulator GFR300C10NWK FAQ
AirTAC publishes G-series flow as curves rather than a single rated number, so there is no one rated-flow figure to quote. Send us your supply pressure and air demand and we will read the sizing off the GFR300 datasheet and confirm it on request.
The N in GFR300C10NWK specifies that no gauge is fitted. Other GFR300 codes carry the embedded square gauge as standard, or an external round gauge with the scale of your choice: 1 = MPa, 2 = psi, 3 = bar. Order the code with the gauge position you need.
