Airtac GFR Filter Regulator GFR300C15AJNW
The AirTAC Airtac GFR Filter Regulator GFR300C15AJNW 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 GFR300C15AJNW
The GFR300C15AJNW is an AirTAC GFR300 filter-regulator: filtration of water and particulate plus pressure regulation in a single body, with no lubrication stage. This 300-size unit takes 1/2 in PT ports (PT is the standard thread for this code), drains its polycarbonate bowl automatically and carries the finer 5 um filter element; no pressure gauge and no reverse valve are fitted in this code. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with the automatic drain, and the working temperature range is -5 to 70 C.
This is a genuine AirTAC part from a family that spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in. Options across the G series include drain type, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar, G (BSPP) or NPT threads, brackets and a reverse valve. Rated flow is published only as curves, not a single figure, so ask us to confirm sizing and we will send the datasheet 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.

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.
Size Class

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 GFR300C15AJNW Is Used
Laboratory and instrument air
Feeding lab benches, analytical instruments and small pneumatics that need cleaner, regulated air: the 5 um element trims particulate ahead of sensitive equipment.
Spray finishing supply
Conditioning air for spray guns and coating lines: the 5 um element keeps particulate out of the finish and the regulator holds a steady atomising pressure at the gun.
Pneumatic tool stations
Air prep for maintenance and assembly benches running air screwdrivers, ratchets and grinders: filtered, regulated supply with automatic condensate draining through the working day.
Is the Airtac GFR Filter Regulator GFR300C15AJNW the Right Unit?
Take 300 with 1/2 in PT ports for general mid-range duty; 400 and 600 give larger ports and more capacity, 200 suits light loads. The automatic drain here empties the bowl without attention, while manual-drain variants suit supervised posts and permit regulation down to 0.05 MPa (7 psi). The 5 um W element is the finer grade, chosen over the 40 um standard where delicate valves, tools or processes need cleaner air. No gauge is fitted, so add a square embedded or round external gauge in MPa, psi or bar if a local reading is wanted. PT is standard with G (BSPP) and NPT as order options, and a bracket can be specified. Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 GFR300C15AJNW FAQ
AirTAC does not publish a single rated-flow figure for the GFR300; performance is given as characteristic curves. Send us your operating pressure and the air demand of your equipment, and we will confirm sizing from the datasheet on request.
This code carries the 5 um W element, the finer grade suited to delicate valves, tools and finishing work; the 40 um standard element is the general-purpose choice for typical plant air. Element grade is one decode choice on GFR units, alongside drain type, gauge and thread options.
