The AirTAC GFR30015LJC2T 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 AirTAC GFR30015LJC2T is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built on the GFR300 size with 1/2 in NPT ports, standard 40 um filtration and a differential-pressure drain that bleeds condensate away as air flows through the unit. It is the low-pressure regulator type, fitted with an external round gauge reading in psi, and no mounting bracket is included. The polycarbonate bowl lets you check the condensate level at a glance.
This is a genuine AirTAC part. The GFR family covers sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT, G and NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (code W) filtration, and square or round gauges in MPa, psi or bar scales. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. AirTAC publishes flow as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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.

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Point-of-use conditioning for the pneumatic cylinders and grippers on a carton-forming or wrapping line: clean, moisture-reduced air held at a stable low pressure for gentle clamping, sealing and pusher motions.
Bench and test-bench setups that need filtered air regulated to a low setpoint - for example leak-testing rigs or sample-handling actuators - where the round psi gauge gives a direct local reading at the rig.
Low-pressure circuits on spinning, weaving or web-converting machinery, where the filter-regulator protects solenoid valves and air jets from water and particulate carried in the shop-air main.
The main decodable choices are size and port: GFR sizes 200, 300, 400 and 600 step up in port and flow capacity, so match the port (here 1/2 in NPT) to your line size and air demand. Drain type is a real decision: differential-pressure (this unit) drains only while air flows, automatic drains on its own, and manual needs a periodic press - choose based on how continuously the line runs. Filtration is 40 um standard; specify the W option for 5 um where finer protection is needed. Gauges come as an embedded square gauge or an external round gauge in MPa, psi or bar scales - this unit reads psi. Thread is NPT here; PT is the AirTAC standard and G (BSPP) is also available to order. AirTAC publishes flow as curves, not a single rating, so 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. 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 rated flow number. Tell us your inlet pressure, set pressure and air demand and we will confirm the sizing from the datasheet before you order.
The L in GFR30015LJC2T marks the low-pressure regulator variant, intended for circuits regulated well below standard line pressure. The exact adjustment range for this variant is not published in the standard tables, so ask us to confirm it from the datasheet. Everything else decodes normally: 40 um filtration, differential-pressure drain, round psi gauge, NPT1/2 ports, no bracket, and a working range of -5 to 70 C.
