Airtac GFR Filter Regulator GFR300C15F1WK
The AirTAC Airtac GFR Filter Regulator GFR300C15F1WK 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 GFR300C15F1WK
The GFR300C15F1WK is an AirTAC G-series filter regulator: filtration and pressure regulation combined in one body, with no lubricator. This configuration is a size 300 unit with PT-threaded 1/2 in ports (PT is the standard thread; G and NPT are catalogue options), a fine 5 um (W) filter element, the standard differential-pressure drain, an embedded square pressure gauge reading in MPa, a reverse/check valve fitted, and a mounting bracket included. The polycarbonate bowl collects water and particulate ahead of the regulated outlet.
This is a genuine AirTAC part. G-series filter regulators are offered in sizes 200, 300, 400 and 600 with a choice of ports, drains, 40 um or 5 um elements, gauge styles and scales, and check valves. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details 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 0.15 - 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)). |

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 GFR Filter Regulator GFR300C15F1WK Is Used
CNC machining center air supply
Feeds tool-changer clamps and pallet-restraint actuators with water- and particle-stripped air held at a fixed pressure, while the check valve helps hold the downstream circuit if supply dips.
Packaging line carton-sealer circuit
Conditions the 1/2 in branch feeding sealing jaws and vacuum generators on a cartoning line, keeping flapper and jaw cylinders working at a stable set pressure.
Spray finishing air drops
Supplies a paint line's gun manifold with finely filtered, regulated air, protecting atomizing equipment from condensate and 5 um-scale contamination.
Is the Airtac GFR Filter Regulator GFR300C15F1WK the Right Unit?
Size 300 with 1/2 in PT ports suits lines that need more flow than 1/4 in or 3/8 in units deliver; step up to 400/600 or down to 200/300 to match demand. Element choice is 40 um standard or 5 um (W) for finer protection of valves and actuators - this unit carries the 5 um grade. The regulator adjusts 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain fitted here; manual-drain variants adjust 0.05-0.9 MPa (7-130 psi). Check valves (K), bracket options, square or round gauges with MPa/psi/bar scales, and G or NPT threads are all selectable. Because flow is published as curves, not a single rating, send us your flow and pressure requirements and we will confirm the right size 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 GFR300C15F1WK FAQ
AirTAC publishes flow for G-series filter regulators as characteristic curves, not a single rated number, so no one figure is quoted here. Share your working pressure and required flow and we will confirm the correct size against the datasheet curves on request.
The W suffix on this unit specifies the 5 um element for finer protection downstream; the blank-element version filters to 40 um and suits general plant air. The drain here is the standard differential-pressure type, and automatic (A) or manual (M) drains are available on the same size as ordering variants.
