The AirTAC GFR30015LF2T AirTAC Filter Regulator NPT1/2 Low-Pressure 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 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.
The AirTAC GFR30015LF2T is a GFR300 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built on the size-300 frame with NPT1/2 ports, a differential-pressure drain on the polycarbonate bowl, standard 40 um filtration, low-pressure regulation, and an embedded square gauge reading in psi. A mounting bracket is included.
It is a genuine AirTAC part, one configuration within the GFR range that spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch and PT, G or NPT threads. 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 the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Supply filtered, regulated air to pneumatic clamps on a machining fixture, holding the set pressure steady through the cutting cycle.
Feed diverters, stoppers and small actuators on a packaging conveyor with clean air at a stable low set pressure.
Provide filtered pilot air to positioners and pilot-operated process valves on a bottling or filling line.
Choose the size by port and flow: this unit is size 300 with NPT1/2 ports; the smaller or larger frames (200/400/600) step the port and flow capacity down or up. Drain options are differential-pressure (this unit), automatic (code A) or manual (code M). Filtration is 40 um standard; specify W for 5 um where finer filtration is needed. The embedded square gauge reads psi here; MPa or bar scales and an external round gauge are alternatives. The thread on this model is NPT; PT (the standard) and G are order options. Because rated flow is published as curves rather than a single number, 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR300 as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet figures and check the sizing before you order.
The L in the code marks the low-pressure regulator variant, intended for applications that need lower set pressures than the standard type. The exact adjustment range for this variant is not published in the material we hold, so please ask us to confirm it against your set pressure before ordering.
