The AirTAC GFR200C08LJNT AirTAC Filter Regulator NPT1/4 Low-Pressure 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 GFR200C08LJNT is an AirTAC GFR filter regulator: water-and-particulate filtration and pressure regulation combined in one body. This size 200 unit carries a 1/4 in NPT port, a 40 um standard filter element and a differential-pressure drain that removes collected condensate as the pressure differential across the element rises. It is built as the low-pressure regulator type, with no gauge fitted and no mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing; the bowl on this size is PC (polycarbonate).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and the range offers a 5 um element (code W), automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads alongside the PT standard. Flow and other datasheet figures are published as curves, so we confirm them for your application 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.

Cleaning and regulating the supply air to clamp and hold-down cylinders on a carton-sealing line, where the circuit runs at a reduced pressure below the standard regulator range.
Conditioning the supply air to pneumatically actuated process valves in a water-treatment plant, keeping particulate and condensed water out of the actuator and positioner air.
Filtering and stepping down shop air to a low-pressure take-off feeding spray equipment and air knives in a finishing booth, with condensate carried off by the differential-pressure drain.
The real, decodable choices in this family are the size and port step, the drain type, the filter grade, the gauge and its scale, the thread, and the bracket. This unit is the size 200 body with a 1/4 in NPT port, a 40 um standard element and a differential-pressure drain, built as the low-pressure regulator type, with no gauge and no bracket. If your circuit runs at reduced pressure, this low-pressure variant is the one to specify; the exact regulation range for it is not published, so ask us to confirm it. For finer filtration choose the W code with its 5 um element; automatic or manual drains, gauges with MPa, psi or bar scales, G (BSPP) threads and brackets are available elsewhere in the GFR range. Flow is published as curves rather than 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 family as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and demand and we will confirm the flow for this exact model from the datasheet on request.
No. The N in the code means no gauge is fitted on this unit. Elsewhere in the GFR range you can specify an embedded square gauge or an external round gauge with MPa, psi or bar scales; ask us to identify the variant that matches your panel.
