The AirTAC GFR20008LNT AirTAC Filter Regulator 1/4 in NPT, 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 PT1/4" 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 GFR20008LNT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size-200 unit with 1/4 in NPT ports, the low-pressure regulator type, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate away automatically as air flows through. The polycarbonate bowl gives a visible check on condensate, a mounting bracket is included, and no pressure gauge is fitted (code N).
It is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drains, a 5 um (W) element option, gauge and thread options, and a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature for this family is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figure for your application.

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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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.

Feeding spray guns on a woodworking or automotive refinishing line that runs at reduced header pressure: the low-pressure regulator type holds a reduced working pressure while the 40 um element and drain keep water and grit out of the gun.
Point-of-use conditioning ahead of cylinders and directional valves on a cartoning or wrapping machine, where one compact body does both the filtering and the pressure setting for a 1/4 in NPT drop.
Bench rigs and laboratory setups that need clean, regulated air at modest pressures, with the polycarbonate bowl giving a visible condensate check and the included bracket allowing frame or panel mounting.
Choose the size and port against the air demand of the circuit: this unit is size 200 with 1/4 in NPT ports, and the larger sizes (300/400/600) carry bigger ports and more flow. The low-pressure (L) regulator type is selected when the circuit runs at reduced pressures below the standard band - confirm the exact adjustment range with us before ordering, as it is not published as a single figure here. Drain choice is differential-pressure (fitted here), automatic (A) or manual (M); the element is 40 um standard with a 5 um (W) option for finer filtration. Thread is NPT on this code; PT is the standard and G (BSPP) is also a catalogue option. A gauge can be specified (embedded square or external round, in MPa, psi or bar scales), and a no-bracket (J) variant exists. Because flow is published as curves rather than one rated number, send us your flow and pressure requirements 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 GFR family as curves rather than a single rated figure, so no one number is quoted here. Tell us your flow and working pressure and we will confirm the sizing from the datasheet before you order.
This code ends in N, which means no gauge is fitted. The family can be ordered with an embedded square gauge or an external round gauge in MPa, psi or bar scales - ask us for the equivalent model with a gauge if you want one supplied.
