The AirTAC GFR30010ALF2T AirTAC Filter Regulator 3/8 in NPT 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 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 GFR30010ALF2T is an AirTAC GFR300 filter regulator: water-and-particulate filtration and pressure regulation combined in a single body, so one unit conditions the air and holds your downstream set pressure. This configuration is built on the 300 size with a 3/8 in NPT port, a 40 um standard filter element, and an automatic drain that expels collected condensate without anyone opening the bowl. The regulator is the low-pressure type, the embedded square gauge is fitted and reads in psi, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, 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); the polycarbonate bowl suits the 300 size. Flow is published as curves rather than a single rating, so ask us to confirm the figures 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.

| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic 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.

Point-of-use conditioning on a carton-sealing or wrapping line: the filter section strips water and pipe scale from the shop-air drop, the regulator holds a steady supply pressure to the cylinders, and the automatic drain keeps the bowl clear through multi-shift running.
Feeding a bench press or clamping fixture where a stable, lower set pressure protects the tooling: the low-pressure regulator type and the psi-reading square gauge make set-and-check straightforward at the cell.
Conditioning the drop ahead of air tools and actuators at an assembly bench: the 40 um element catches scale and debris, the automatic drain handles condensate on its own, and the included bracket mounts the unit to the machine frame.
Choose the size by port and flow: the 300 size with its 3/8 in NPT port sits mid-range in the GFR line-up (200/300/400/600), so step up or down if your circuit needs a different connection. Drain: this unit has an automatic drain; manual (M) and differential-pressure (blank) versions exist in the same size if that suits the installation better. The filter grade here is the standard 40 um element - specify code W for 5 um where finer particulate matters. The square gauge reads psi; MPa or bar scales and an external round gauge are options. Thread is NPT on this model; PT (the standard) and G are order options, and the bracket is included. Flow is published as curves, not a single rating - send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
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 rather than a single rated figure, so there is no one number we can honestly quote. Tell us your required flow and working pressure and we will confirm the figure from the datasheet for this exact model before you order.
The A in the code means the bowl expels collected condensate automatically, with no manual draining to remember. Manual (M) and differential-pressure (blank) drain versions are available in the same 300 size if your installation suits them better.
