The AirTAC GFR400C15ANT AirTAC Filter Regulator 1/2 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 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 GFR400C15ANT 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 1/2 in NPT, carries the 40 um standard filter element, and drains its bowl automatically, so accumulated condensate is expelled without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi); no gauge is fitted (code N), and a mounting bracket is included.
It is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, manual or automatic drain choices, an optional 5 um element (code W), gauge options and G (BSPP) or NPT threads as catalogue alternatives to the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet 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. 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.

Filtered, regulated air feeding gripper and valve manifolds on assembly robots. The 1/2 in NPT port suits a main drop line serving several actuators, and the automatic drain keeps condensate out of the circuit without operator rounds.
A set-pressure supply to spray stations and air tools where moisture and pipe scale would spoil finish quality. The 40 um element catches particulate while the auto-drain bowl handles water at each drop.
Stable regulated pressure for the pneumatic cylinders that push, clamp and divert packs along conveyor lines. The combined filter-regulator body saves panel and drop-line space compared with separate filter and regulator units.
Step through the real choices before ordering. Size and port set the capacity: this 400-size unit takes a 1/2 in NPT connection; smaller or larger sizes step down or up from 1/8 to 1 in. Drain type matters in duty terms: this model drains automatically (code A), while manual (M) and differential-pressure (blank) are the other catalogue choices. Filter grade is 40 um as fitted here, with 5 um (code W) available when finer protection is needed. No gauge is fitted on this version; gauge-equipped units offer an embedded square gauge or an external round gauge with MPa, psi or bar scales. Thread is NPT on this model; PT is the AirTAC standard and G (BSPP) is also a catalogue option. A bracket is included (code J deletes it).
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a flow number. Send us your line pressure and downstream demand and we will confirm the 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your inlet pressure and the downstream demand, and we will confirm the sizing from the datasheet on request.
The N code means no gauge is fitted on this unit. GFR regulators in the series are available with an embedded square gauge or an external round gauge, with MPa, psi or bar scales, so ask for a gauge version if you need a visible setpoint. This unit also drains its bowl automatically, so no manual draining routine is required.
