The AirTAC GFR300C15LJF1TK 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 See datasheet 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 GFR300C15LJF1TK is an AirTAC GFR300 filter regulator: filtration and pressure regulation combined in a single body, so one unit removes water and particulate from compressed air and holds a set downstream pressure. This configuration is built for 1/2 in NPT ports in the size-300 frame, with a 40 um standard filter element, a metal bowl with differential-pressure drain, the low-pressure regulator type, an embedded square gauge scaled in MPa, a fitted reverse (check) valve, and no mounting bracket. 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 family is offered in sizes 200, 300, 400 and 600 with a choice of ports and threads (PT standard; G and NPT to order), differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, embedded square or optional external round gauges with MPa, psi or bar scales, and bracket choices. Flow for this family is published as curves rather than a single rating, so ask us to confirm the figures and the datasheet for this exact model 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.

Feeds filtered air at a steady regulated pressure to the clamp cylinders on a CNC fixture, with the fitted check valve blocking reverse flow in the circuit. One body handles both the air preparation and the pressure setting at the fixture drop.
Sits at the drop line feeding air tools and hold-downs in a fabrication cell where this unit's metal bowl is specified instead of the family's standard polycarbonate bowl. It strips water and particulate from the shop air and sets the working pressure for the station.
Conditions the air supply to applicator heads on a converting or packaging line, where the low-pressure regulator type is chosen to work below the range of a standard regulator. The 40 um element protects nozzles and valves from dirt and condensed water.
The real choices on this family are all decodable from the code. Step size and port to the line: sizes 200, 300, 400 and 600 pair with ports from 1/8 in up to 1 in, and the right step depends on the flow your line needs - which is published as curves, not a single rating, so let us check the sizing against your application before you order. Choose the drain (differential-pressure as here, automatic, or manual), the filter grade (40 um standard, 5 um with code W), the gauge (embedded square as here, or an optional external round gauge, scaled in MPa, psi or bar) and the thread (PT is the standard; G and NPT are order options). This unit is the low-pressure regulator type with a metal bowl, a fitted check valve and no bracket; the same family is offered with bracket included where mounting is needed.
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 this family as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure, downstream demand and port size, and we will confirm the flow from the datasheet for this exact model on request before you order.
The L marks the low-pressure regulator type on this GFR300 unit. Its exact setting range is not published in the material we hold, so we confirm it on request. The unit otherwise follows the family limits: 1.0 MPa (145 psi) maximum inlet pressure and -5 to 70 C operation, non-freezing.
