The AirTAC GFR30015ANTK AirTAC Filter Regulator NPT1/2 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 PT1/2" ports, a automatic 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.
The GFR30015ANTK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady, in a single body. This configuration is the 300 size with a 1/2 in NPT port, an automatic drain that expels collected condensate without manual attention, a 40 um filter element, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a reverse/check valve fitted. No gauge is supplied with this code, and the bowl at this size is PC (polycarbonate). Operating temperature is -5 to 70 C (non-freezing) and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with PT, G (BSPP) and NPT thread options, drain choices of differential-pressure, automatic or manual, a 5 um element option (code W), gauge and reverse-valve options, and an optional bracket (a bracket is included on this code). Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures against your application before ordering.

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.

| N | No pressure gauge (N). |
| (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.
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.

Feeding clean, regulated air to a pneumatic press or clamping fixture, where the fitted check valve helps hold the set downstream pressure if the upstream supply dips.
Point-of-use conditioning ahead of packaging machine cylinders and valves, with the automatic drain handling condensate on a line that runs unattended between shifts.
A plant air drop serving air tools and actuators, where the 40 um element catches pipe scale and rust and the 1/2 in port suits a higher continuous draw.
Work from your required flow down to the size and port: 200, 300, 400 and 600 step up in port and flow capacity, and this code is the 300 size with a 1/2 in NPT port. Choose the drain to suit access: automatic (this code) drains itself, manual suits attended installations, and differential-pressure drains on a pressure drop - note the adjustment range differs by drain type (0.15-0.9 MPa with automatic or differential drain, 0.05-0.9 MPa with manual). The 40 um element is standard here; specify 5 um (code W) when finer filtration is needed. Thread is PT as standard with G (BSPP) and NPT as order options - this code is ordered in NPT. Gauge and reverse-valve options are chosen at ordering; this code carries a check valve and no gauge. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and downstream pressure and we will confirm the datasheet figures and check that the 300 size with the 1/2 in port suits your application.
The A in the code selects an automatic drain, which expels collected condensate without manual attention - useful where the unit is mounted in an awkward or unattended spot. With an automatic drain the regulator adjusts 0.15-0.9 MPa (20-130 psi); manual-drain versions adjust 0.05-0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi).
