The AirTAC GFR40015ALC2T 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 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 GFR40015ALC2T is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the 400 size with a 1/2 in NPT port, an automatic drain that expels collected condensate from the PC bowl without manual attention, a 40 um standard filter element, the low-pressure regulator type, and a round pressure gauge reading in psi. A mounting bracket is included, and the unit carries no reverse/check valve.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, and square or round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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. 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.

|---|---|
| 15 | Port size PT1/2". This body offers 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). |
| C | Gauge shape: Round. 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.

Installed ahead of a directional-valve manifold on an assembly line, it strips condensate and debris from the 1/2 in supply and holds a steady low regulated pressure to the valves.
Mounted at the air inlet of a cartoning or wrapping machine, it conditions the factory air supply and lets the set-up technician read line pressure directly on the round psi gauge.
Feeding instrumentation or actuator circuits that run at reduced pressure, the low-pressure regulator type and automatic drain keep the panel supplied with clean, settled air.
Step up through the GFR sizes (200/300/400/600) as your port and flow demand grows; the 400 size with a 1/2 in NPT port suits lines running larger-bore supply. Choose the drain to match access: automatic (this model) for unattended condensate removal, manual for periodic attention, differential-pressure as the default. Filtration is 40 um standard; specify W for the 5 um element where downstream equipment needs finer protection. This unit carries the low-pressure regulator type and a round psi gauge; square embedded gauges and MPa or bar scales are alternatives. PT is the standard thread, with G and NPT as order options, and a bracket is included.
Because flow is published as curves rather than a single rating, 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 GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Ask us and we will confirm the datasheet flow curve and help you size the unit against your application before you order.
The A in the code selects the automatic drain, which expels collected condensate from the PC bowl without manual attention, and C2 selects the optional external round gauge with a psi scale. Alternatives in the family are manual or differential-pressure drains and an embedded square gauge with MPa, psi or bar scales.
