The AirTAC GFR30010LF1T AirTAC Filter Regulator NPT3/8 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 PT3/8" 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 GFR30010LF1T is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This size 300 unit is built with 3/8 in NPT ports, the standard 40 um filter element, a differential-pressure drain, the low-pressure regulator type, and a square pressure gauge with MPa scale fitted. The polycarbonate bowl lets you see collected condensate at a glance, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and G or NPT thread options alongside the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the sizing figures from the datasheet 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.
| GFR300 | G-series filter regulator, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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)). |
| 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. |
| 1 | Gauge scale: MPa. 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. |
| (blank) | No reverse-flow valve (the default). |
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 filtered, regulated air to grippers and clamp cylinders on a bottling line, with the bowl catching compressor moisture before it reaches the valves.
Supplying pressure-controlled air to diverter and stopper gates on a conveyor system, where the low-pressure regulator type suits gentle actuation circuits.
Providing clean, regulated air to small pneumatic actuators on a laboratory or pilot-plant skid, with the MPa gauge giving a local setpoint readout.
Within GFR you step by size and port - 200, 300, 400 or 600 with ports from 1/8 to 1 in - matched to the air demand of your circuit; we can check the published flow curves against your requirement before you order. This code is the low-pressure regulator type; its exact adjustment range is not published, so confirm it with us against your setpoint. Drain here is differential-pressure, with automatic and manual as the other catalogue choices. Filtration is the standard 40 um element (5 um with code W), and the square gauge reads in MPa with psi and bar scales available. Thread is NPT on this unit; PT is the standard and G is also offered. A reverse/check valve can be added as code K.
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 GFR flow as curves, not a single rated figure, so we do not quote a number here. Send us your required flow and line pressure and we will confirm from the datasheet whether this 3/8 in size suits your application before you order.
The L marks the low-pressure regulator variant rather than the standard type. Its adjustment range is not published in the catalogue, so confirm the range with us against your setpoint. Maximum inlet pressure remains 1.0 MPa (145 psi), and the other decoded features - NPT3/8 ports, 40 um element, differential-pressure drain and square MPa gauge - are unchanged.
