The AirTAC GFR30015AJC2T 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 automatic 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 GFR300-15AJC2T is a 300-size filter regulator that removes water and particulate from compressed air and holds downstream pressure in one body. This configuration has a 1/2 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a round pressure gauge reading in psi. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing), and the polycarbonate bowl lets you see the condensate level at a glance.
This is a genuine AirTAC part supplied by airdistr.com. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, plus thread options (PT standard, G and NPT to order), drain types, 5 um elements and gauge choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

Mounted at the drop to a carton-forming and sealing section, the GFR300-15AJC2T cleans water and debris from the plant air and holds a steady regulated pressure to the cylinders, while the automatic drain keeps condensate off the line without daily attention.
At a clamping and pressing fixture fed by half-inch drops, this filter regulator gives one point of filtration and pressure control for the station's valves and actuators, with the round psi gauge letting operators verify set pressure at a glance.
On a leak-test or calibration bench where clean, stable air matters, the 40 um element and regulator in one body protect sensitive gauges and transducers, and the automatic drain suits a bench that runs unattended between shifts.
Size 300 with a 1/2 in NPT port suits lines where moderate-to-larger air consumption and half-inch piping are the norm; step up to size 400/600 or down to 200 as your flow and porting require. The automatic drain here is the right choice when the unit sits where regular manual draining is impractical; manual and differential-pressure drains are available on other codes. The 40 um element is the standard general-purpose grade - specify the W variant if you need 5 um. The round psi gauge is fitted on this code; embedded square gauges and MPa/bar scales are the alternatives. NPT threading is an order option alongside the PT standard, and a mounting bracket can be added where the J (no bracket) code does not suit.
Flow for this family is published as curves, not a single rated figure, so we cannot honestly quote one number. Send us your application details and we will confirm 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 GFR300 series as curves, not as a single rated figure, so we do not quote one number here. Tell us your application and required conditions and we will confirm the flow figures from the datasheet on request before you order.
The A in the code means an automatic drain, which discharges collected condensate from the bowl without anyone opening it - useful where the unit is mounted in an awkward spot or runs unattended. The GFR family also offers manual drain (code M) and the differential-pressure drain that is the catalogue default, so you can pick the drain style that matches your maintenance routine.
