The AirTAC GFR40010ALC2T AirTAC Filter Regulator NPT3/8 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 AirTAC GFR40010ALC2T is a GFR400-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration is the size 400 unit with a 3/8 in NPT thread, an automatic drain that expels collected condensate without manual attention, the standard 40 um filter element, the low-pressure regulator type, a round pressure gauge reading in psi, and the mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, standard or low-pressure regulation, gauge scale options and bracket variants. Full datasheet and flow figures are confirmed 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.

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 at the drop to a cartoning or wrapping line, this unit cleans condensed, particle-laden shop air and holds a steady reduced pressure to the machine's pneumatic cylinders, with the automatic drain handling condensate between shifts.
Mounted on the air-preparation panel feeding torque tools and clamps at an assembly bench, the 3/8 in NPT connection matches the main header while the psi gauge gives operators a clear local setpoint reading.
Used ahead of actuators and air bearings on laboratory automation or test rigs, where the 40 um element protects sensitive components and the low-pressure regulator type suits circuits that operate at reduced supply pressures.
Size 400 with a 3/8 in port sits in the middle of the GFR range; step up to 600 or down to 300/200 depending on the pipe size and flow your line carries. The automatic drain on this unit suits installations that are not checked daily; choose manual or differential-pressure drain variants if you prefer controlled or demand-based purging. The 40 um element is the standard grade; specify the W suffix for 5 um when finer particle capture is needed. The round gauge on this code reads in psi; MPa and bar scales are also available. PT is the standard thread, with G and NPT as order options - this code carries NPT. A bracket is included. The low-pressure regulator type is intended for circuits that run at reduced setpoints; the exact regulation range for this variant is not published in our sheet, so ask us to confirm it against your setpoint before ordering. Flow for this series is published as curves rather than a single rated figure, so send us your application details and we will confirm sizing 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 GFR series as characteristic curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, setpoint and downstream demand and we will confirm the flow and full datasheet figures for this exact model on request.
The A in the code GFR40010ALC2T means the bowl drains collected condensate automatically, which suits installations that are not attended daily. The same GFR400 body is also available with a manual drain or the default differential-pressure drain - just ask for the matching code.
