The AirTAC GFR200-08LJNT 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 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 GFR200-08LJNT is an AirTAC GFR200 filter regulator: one body that both removes water and particulate from compressed air and regulates downstream pressure. This configuration has 1/4 in NPT ports, is the low-pressure type (code L), and carries the standard 40 um filter element. Condensate is handled by the differential-pressure drain in the PC bowl, which discharges automatically when the pressure differential across the drain reaches its threshold. No gauge is fitted (code N) and no mounting bracket is included (code J), so plan your panel or machine mounting accordingly.
This is a genuine AirTAC part. The GFR200 is the compact size in the GFR range, which steps up through 300, 400 and 600 bodies with larger ports and higher flow capacity; options across the range include a 5 um element (code W), automatic or manual drains, gauge variants, and G (BSPP) or NPT threads in place of the PT standard. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

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.

On an assembly line where workpieces are held by air clamps that must not be crushed, this low-pressure-type filter regulator cleans the supply and holds the reduced circuit pressure the clamping cylinders need, with the differential-pressure drain keeping condensate out of the fixture valves.
On a cartoning or case-packing line, diverters, pushers and hold-down cylinders run on a reduced-pressure branch; the GFR200-08LJNT filters water and scale from the shop air and regulates that branch, protecting the directional valves and cylinders downstream.
In a laboratory or pilot plant where instruments, agitators or sample-handling actuators are fed from a low-pressure air header, this unit conditions the supply at the header take-off and regulates it to the level the devices require, with NPT1/4 ports matching common lab pipework.
Start with the port and flow step: the GFR200 with its 1/4 in ports is the smallest GFR body, so if your line's air demand sits above the 200-size curve band, step up to GFR300 or larger - we can check the curves against your consumption. Choose the drain to match the duty: differential-pressure (this model) discharges on its own as condensate builds, automatic (code A) drains continuously, and manual (code M) needs an operator to bleed the bowl. Filter grade is 40 um standard; specify W if you need 5 um. This unit is the low-pressure type (L) and ships without a gauge (N) or bracket (J); gauge variants and brackets are available on other codes in the family. Thread here is NPT; PT is the catalogue standard and G (BSPP) is an order option.
Because AirTAC publishes flow as curves rather than one rated number, ask us to confirm sizing against your application 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 rated flow, Cv or SCFM number. Tell us your application and air consumption and we will confirm the relevant datasheet curve figures for you before you order.
L marks the low-pressure type of regulator, intended for circuits regulated well below standard line pressure; the exact adjustment range for this variant is not published in the sheet we work from, so ask us to confirm it. N means no gauge is fitted and J means no mounting bracket is included - gauge variants and bracketed codes exist in the GFR family if you need them.
