The AirTAC GFR40015JC2TK AirTAC Filter Regulator NPT1/2 with Gauge 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 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 GFR40015JC2TK is an AirTAC GFR400 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This 1/2 in NPT configuration uses the 40 um standard filter element with a differential-pressure drain that bleeds collected condensate whenever the pressure drop across the element rises, an external round gauge reading in psi, and a built-in reverse/check valve that holds the downstream setting when upstream supply is lost. Supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR400 series, one of four sizes (200/300/400/600) with port options from 1/8 in to 1 in and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so we confirm datasheet 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. 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.

Filtering and regulating the 1/2 in branch line that feeds air tools and clamping fixtures along an assembly hall, with the psi gauge giving operators a local setpoint readout.
Conditioning the air feeding cylinders and diverters on a packaging conveyor, where the check valve holds the regulated pressure if the main supply dips during a shift.
Supplying clean, regulated air to pneumatic actuators on laboratory automation equipment, with the 40 um element catching pipeline scale and the differential-pressure drain keeping moisture off the instruments.
Size 400 with a 1/2 in NPT port suits lines with higher air demand; step down to 200/300 or up to 600 if your flow requirement or existing pipe size differs. The 40 um element is the standard choice for general plant air; specify the W option (5 um) only where finer filtration is needed. Drain is differential-pressure here - choose automatic (code A) for unattended drains or manual (code M) where you want controlled purging. The round gauge reads psi; square embedded gauges and MPa or bar scales are available. Thread is NPT; PT and G (BSPP) versions can be ordered, and a J-code bracketless build like this one omits the mounting bracket.
Because AirTAC publishes flow as curves rather than a single rated figure, 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. The reflux valve permits reverse flow 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 number, so there is no one figure we can honestly quote. Tell us your application and required flow and we will confirm the sizing from the datasheet curves on request before you order.
A blank drain code means the differential-pressure drain: condensate is expelled automatically when the pressure drop across the 40 um element rises, with no operator action. If you prefer a fully automatic drain or a manual drain, the A and M variants of the same GFR400-15 unit can be ordered instead.
