The AirTAC GFR40015JC1TK 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 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 GFR40015JC1TK is an AirTAC GFR400 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is built around a 1/2 in NPT port on the size 400 body, with the standard 40 um filter element and a differential-pressure drain that bleeds collected condensate automatically as flow passes through. The set downstream pressure is read on the fitted round MPa gauge, and the built-in reverse/check valve holds the setting if upstream supply is interrupted. It is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, a choice of drain type, a 5 um element option, gauge scale choices and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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.

At a 1/2 in NPT take-off on the main header, this unit cleans water and particulate from the plant supply and holds a steady set pressure to the assembly cell's air tools and cylinders, with the MPa gauge giving the operator a clear setting reference.
Carton sealers and wrapping lines need clean, stable air for their clamp and fold cylinders. Mounted at the machine inlet, this filter regulator conditions the supply and the check valve keeps the setting through brief supply dips.
On a test bench or laboratory air line, the 40 um element strips water and pipe scale before instruments, while the regulator gives a repeatable set pressure for each test run, read directly off the fitted round gauge.
Start with the port and size step: this unit is size 400 with a 1/2 in NPT port, one step above the 300 series, so step up if your line runs larger ports or higher demand, or step down for compact circuits. The 40 um element suits general plant air; specify the W code if you need 5 um for finer downstream equipment. Drain choice matters: the differential-pressure drain here is maintenance-light, while automatic and manual drains are available in the family. Gauge scale (MPa, psi or bar), thread family (PT standard, G and NPT to order) and bracket inclusion are all decodable options.
Because flow is published as curves rather than a single rated figure, send us your application details 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. The reflux valve permits reverse flow 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 application and we will confirm the datasheet flow curve and sizing for this unit on request.
This unit's differential-pressure drain vents collected condensate automatically whenever air flows through the unit, with no operator action. If you prefer a float-type automatic drain or a simple manual drain, those are available as coded options in the GFR family.
