The AirTAC GFR400C15ALC2T AirTAC Filter Regulator NPT1/2 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 See datasheet 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 GFR400C15ALC2T is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 400 unit is threaded NPT1/2 and carries the automatic drain, so collected condensate is expelled without manual attention. The standard 40 um filter element is fitted, the regulator is the low-pressure type, and an external round gauge scaled in psi is included; a mounting bracket comes with the unit and no reverse/check valve is fitted. 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 offered in sizes 200, 300, 400 and 600 with ports from 1/8" up to 1", a choice of differential-pressure, automatic or manual drain, a 5 um element option (code W), embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application from the datasheet.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

Placed ahead of clamping cylinders on a fixture panel, this unit strips condensate and chips-laden moisture from the shop air and holds the reduced, low-pressure setting the clamps are set up for, with the psi gauge giving the operator a direct reading at the station.
On a carton-forming or film-sealing packaging line, this filter regulator cleans the compressed air feeding seal cylinders and diverting actuators and keeps their supply pressure steady through the shift, while the automatic drain clears accumulated water without operator rounds.
Feeding the gripper and rotary actuators of a robotic assembly cell, this unit removes water and particulate from the drop before it reaches sensitive components and regulates the supply to the pressure the cell was commissioned at, with the included bracket simplifying panel mounting.
Size 400 with a 1/2 in port sits toward the higher-flow end of the GFR range; step between sizes 200, 300, 400 and 600 to match the port and flow your line needs. Drain is automatic on this unit; the differential-pressure default and a manual drain are also available in the family. The 40 um element is standard - specify code W if the application needs the 5 um grade. This unit carries an external round gauge scaled in psi; the embedded square gauge and MPa or bar scales are the other options. Threads come as PT (the standard), G or NPT - this unit is NPT. Flow is published as curves, not a single rating, so 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 GFR series as curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure, downstream demand and port size, and we will confirm the flow figures for this exact unit from the datasheet on request before you order.
The A in the code GFR400C15ALC2T selects the automatic drain, which expels collected condensate from the bowl without manual attention - useful on lines that run unattended. The family also offers the differential-pressure drain (the default when no drain letter appears) and a manual drain; choose the type that matches how the machine is operated.
