The AirTAC GFR400C15AJF1TK 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 AirTAC GFR400C15AJF1TK is a GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation in a single 400-size body with 1/2 in NPT ports. This configuration carries the standard 40 um filter element, an automatic drain that bleeds collected condensate from the polycarbonate bowl without manual attention, an embedded square pressure gauge scaled in MPa, and a reverse (check) valve. The standard regulator adjusts outlet pressure from 0.15 to 0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature range of -5 to 70 C (non-freezing). No mounting bracket is included with this code.
This is a genuine AirTAC part from the G-series air-treatment line, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT as the standard thread and G (BSPP) or NPT as order options. Drain, filter grade, gauge scale and bracket choices vary by code. Rated flow for this series is published as curves rather than a single figure, so we confirm flow and full datasheet details on request before you order.

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.

Feeding clean, regulated air to tool-clamp cylinders and pallet-changing actuators on a machining centre, with the automatic drain keeping condensate out of the bowl during long unattended shifts.
Conditioning the air feeding gripper and divertor cylinders on a carton packaging line, where the regulator holds a stable setting for consistent clamp force and the check valve guards against backflow.
Supplying filtered, regulated air to pick-and-place modules and sample-handling valves in lab automation, where the 40 um element and MPa-scaled gauge support repeatable day-to-day setup.
Choose the size and port step against the air demand of the circuit: this unit is size 400 with 1/2 in NPT ports, one step up from the 300 series, and larger sizes carry higher flow capacity - we will confirm the exact curve for your application. Drain type is a real choice on this family: automatic (as coded here) empties the bowl on its own, manual requires operator action, and the default differential-pressure drain uses the pressure drop across the element. Filter grade is 40 um standard, with 5 um available as code W where finer filtration is needed. The embedded square gauge is standard, an external round gauge is optional, and gauge scales can be ordered in MPa, psi or bar. Thread is PT as standard; G (BSPP) and NPT (as on this code) are catalogue options. Brackets are optional on GFR units, and this code specifies no bracket.
Because flow for this series 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 GFR series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the flow and full datasheet details for this unit on request before you order.
On this code the drain is automatic: condensate collected in the bowl is discharged without operator attention, which suits installations that run unattended. The manual-drain variant requires someone to open the drain by hand, and the default differential-pressure drain discharges based on the pressure drop across the element. All three are catalogue choices on the GFR family.
