The AirTAC GFR30015ALJC1T 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 GFR30015ALJC1T is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration carries a 1/2 in NPT port, an automatic drain that discharges collected condensate without manual attention, the standard 40 um filter element, and the low-pressure regulator type. A round pressure gauge with MPa scale is fitted, and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, automatic, manual or differential-pressure drains, 40 um or 5 um (code W) filtration, gauge and scale options, and bracket or no-bracket builds. At size 300 the polycarbonate bowl is standard; only size 600 uses an aluminium alloy bowl. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing or any datasheet figure against 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 supply to pneumatic screwdrivers, clamps and air cylinders at workstations along an assembly line, with the automatic drain handling condensate in an enclosed drop and the MPa gauge giving a local readout.
Supplying cleaned, regulated air to the pick-and-place cylinders and sealing jaws on a packaging or cartoning line, where the 40 um element helps protect valve and cylinder seals from particulate carryover.
Feeding impact wrenches, blow guns and bench circuits in a plant maintenance shop, with the filter regulator set at the drop point so tools receive filtered air at the pressure the technician selects.
Size and port set the air capacity: GFR300 takes a 1/2 in port in this build, and the larger the size (200/300/400/600), the larger the port and the greater the flow capacity - match the size to your line's demand. Choose the drain to suit access: automatic (this unit) suits enclosed or infrequently attended installations, manual suits periodic checks, and differential-pressure is the catalogue default. Filter grade is 40 um standard; specify W for 5 um where finer particulate removal matters. Gauge scale is selectable (MPa, psi or bar) and this unit carries the round gauge at MPa. Thread is NPT here; PT is the standard and G is also an order option. This build has no mounting bracket. Flow is published as curves, not a single rating, so send us your flow demand and we will confirm sizing from 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your line's flow demand and operating pressure and we will confirm sizing from the datasheet on request.
The L in GFR30015ALJC1T marks the low-pressure regulator variant of the GFR series. The exact adjustment range for this variant is not published in the catalogue data we hold, so confirm your required set pressure with us on request. Maximum inlet pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C.
