Airtac GFR Filter Regulator GFR300C15AJN
The AirTAC GFR Filter Regulator GFR300C15AJN 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 GFR300C15AJN
The GFR300C15AJN is an AirTAC GFR300 filter-regulator: filtration of water and particulate together with pressure regulation in one 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 standard 40 um filter element; no pressure gauge is 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. The G series covers sizes 200 through 600 with ports from 1/8 to 1 in, and options include drain type, 5 um elements, embedded square or external round gauges in MPa, psi or bar, G (BSPP) or NPT threads, brackets and a reverse valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing and we will supply 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.

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 GFR300C15AJN Is Used
Assembly-cell air drops
Point-of-use conditioning on a drop feeding assembly benches and air tools: filtered, regulated air at a set pressure, with the automatic drain handling condensate through the shift.
Blow-off and air-knife stations
Supplying nozzles and air knives that clear chips or dry parts on a production line: the 40 um element stops pipe scale and rust reaching the nozzles while the regulator sets the blowing pressure.
Conveyor diverters and stops
Running pneumatic diverters, stops and pushers on conveyor lines: stable regulated pressure gives consistent cylinder action, and the auto drain suits continuous operation.
Is the Airtac GFR Filter Regulator GFR300C15AJN the Right Unit?
Match the 300 size and its 1/2 in PT ports to the consumption of the machines downstream; smaller 200 units suit light circuits and 400 or 600 serve higher demand. The automatic drain keeps condensate off the bowl without operator rounds, while manual-drain variants suit attended posts and allow regulation down to 0.05 MPa (7 psi). The standard 40 um element here is the general-purpose grade; specify the 5 um W option where finer protection matters. No gauge is fitted, so add the embedded square gauge or an external round gauge in MPa, psi or bar if a local reading is needed. PT is standard, G (BSPP) and NPT are order options, and a bracket can be added. Since AirTAC publishes flow as curves, not 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 GFR300C15AJN FAQ
There is no single rated-flow figure for this unit: AirTAC publishes GFR300 performance as characteristic curves. Send us your line pressure and the air demand of the equipment involved, and we will confirm sizing from the datasheet on request.
Yes. The gauge is a decode choice on GFR units: N leaves the regulator without a gauge, while embedded square gauges and external round gauges in MPa, psi or bar scales are order options. Drain type, element grade (40 or 5 um), thread and bracket are specified the same way.
