The AirTAC GFR20006LJNT AirTAC Filter Regulator, NPT1/8, 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 PT1/8" 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 GFR200 series combines water and particulate filtration with pressure regulation in a single compact body, so one component does the job of a filter and a regulator. This unit, GFR20006LJNT, is the 200 size with a 1/8 in NPT port, built as the low-pressure type for circuits that run below standard line pressure. It carries the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and a polycarbonate bowl suited to the 200 frame. The J and N codes mean no mounting bracket and no gauge are fitted, so it mounts directly on the line and is set by the adjuster without a local pressure readout.
This is a genuine AirTAC part. The GFR family spans the 200, 300, 400 and 600 sizes with port sizes stepping up from 1/8 in to 1 in, and options include a 5 um element (code W), manual or automatic drains, gauge versions with square or round dials and MPa, psi or bar scales, a reverse/check valve, and G (BSPP) or NPT thread in place of the PT standard. Flow is published 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.

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 a fixture where pneumatic clamps are specified to run gently below normal shop-air pressure, this low-pressure-type GFR filters the incoming air and holds the reduced setting, with the 40 um element keeping scale and pipe debris out of the clamp valves.
Bench-top analytical and test instruments fed from a shop-air drop need clean, settled air at a modest pressure. This unit strips water and particulate at the bench connection and lets the operator dial in the supply pressure the instrument expects.
Small packaging lines use short air runs for blow-off and actuation at reduced pressure. Mounted at the drop feeding the conveyor's pneumatic stations, this filter regulator conditions the air and keeps the downstream cylinders and nozzles on a stable supply.
Start with the port step: the 200 size is the smallest GFR frame at 1/8 in, and moving to 300, 400 or 600 buys larger ports and more flow capacity, so match the frame to the air demand of the circuit rather than upsizing blindly. Choose the drain next: differential-pressure drains bleed condensate as air flows and suit lines with steady use, automatic drains empty the bowl on a cycle, and manual drains (code M) suit intermittent duty where an operator can bleed the bowl. The standard element is 40 um; specify code W for the 5 um element when downstream equipment needs finer protection. For pressure readout, gauge-fitted versions carry an embedded square gauge or an optional external round gauge with MPa, psi or bar scales; this unit is the no-gauge code. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a bracket can be added where the J code here omits it. Because flow is published as curves and not a single rating, send us your application details 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 series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Send us your application details and we will confirm the flow data from the datasheet and check the sizing against your air demand before you order.
The N code in GFR20006LJNT means no gauge is supplied, so the output pressure is set on the adjuster without a local readout. If you want a pressure indication at the unit, gauge-fitted GFR versions are available with an embedded square gauge or an external round gauge in MPa, psi or bar scales - ask us and we will identify the right gauge-coded model for your line.
