The AirTAC GFR30015JC1TK 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 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 AirTAC GFR30015JC1TK is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 1/2 in NPT port, the standard 40 um filter element, a differential-pressure drain, a round pressure gauge reading in MPa, and a built-in reverse (check) valve that holds the downstream setting when upstream pressure is lost. The polycarbonate bowl lets you see accumulated condensate at a glance, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT as order options), drain types, 40 um or 5 um filtration, gauge styles and scales. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeds clean, pressure-controlled air to carton-sealing and wrap stations on a packaging line, with the check valve holding the setting through upstream pressure dips.
Conditions the air feeding conveyor gate cylinders and diverters, filtering out water and pipe scale while holding a steady regulated pressure for repeatable actuation.
Prepares shop compressed air for brake-testing rigs and pneumatic service tools at service benches, where the 1/2 in NPT port suits higher-draw bays.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with a 1/2 in NPT port, one step up from 3/8 in. Filtration is the standard 40 um grade; the 5 um option (code W) suits finer downstream needs. The differential-pressure drain bleeds condensate automatically with flow; choose automatic or manual drain variants if your duty cycle calls for it. The round gauge here reads in MPa, with psi and bar scales available, and the embedded square gauge is the standard alternative. The T in the code specifies NPT thread; PT is the standard and G (BSPP) is also orderable. Note this unit comes without a bracket.
Because flow is published 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 GFR series as curves, not as a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow curve and datasheet figures for this unit on request before you order.
The C in the code specifies an external round gauge fitted, and the 1 sets its scale to MPa (psi and bar scales are available as order options); the embedded square gauge is the standard alternative. The K specifies a built-in reverse (check) valve, which holds the downstream pressure setting if upstream supply is interrupted.
