The AirTAC GR20006LJC3TK AirTAC Air Pressure Regulator NPT1/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT1/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR20006LJC3TK is an AirTAC GR-series air pressure regulator: it does one job, holding a stable downstream pressure from a compressed-air supply, and it carries no filter, bowl or lubricator. This is the low-pressure type, so its adjustment range runs up to 0.4 MPa, and it is built in the compact GR200 size with a 1/8 in NPT port. A round pressure gauge scaled in bar is fitted so the set point can be read directly, and the K option adds a reverse (check) valve so downstream pressure is held if the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -20 to 70 C, and this configuration comes without a mounting bracket; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in standard and low-pressure types, with or without gauge, bracket or check valve, and in PT, G or NPT thread. Flow is published in the catalogue as curves rather than a single rated figure, so tell us your application and we will confirm the sizing and datasheet figures on request before you order.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |

Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with 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 rather than from a single rated figure.

On a bottling or filling machine, small pneumatic cylinders and poppet valves often need a gentle, stable supply well below main-line pressure. This low-pressure GR200 regulator, set up to 0.4 MPa with its bar gauge visible on the panel, holds that set point for the actuation circuit, while the fitted check valve keeps downstream pressure in place if the main air drops out.
Assembly fixtures with light-duty swing clamps or hold-downs frequently run on a reduced, closely held pressure so parts are gripped without distortion. Feeding the clamp bank through this GR200 regulator at a 1/8 in NPT branch connection gives the fixture its own stable low-pressure zone, isolated from the shop-air header by the built-in check valve.
Bench-top analysers, sample-handling pneumatics and small lab actuators typically want a low, steady air pressure rather than full shop supply. This GR200 low-pressure regulator steps the incoming line down to the instrument's working band, the bar-scaled gauge lets the technician verify the setting at a glance, and the -20 to 70 C range covers typical indoor lab conditions.
Start with the port step: GR200 with a 1/8 in port suits the smallest branch lines, while GR300, GR400 and GR600 step up in port size and flow path for larger lines - match the size to the flow your circuit needs. This unit is the L low-pressure type, correct where the downstream set point must stay at or below 0.4 MPa; for higher set points choose the standard GR type. The fitted round gauge here reads in bar; MPa and psi scales are also catalogue options. Thread is NPT on this code, with PT (standard) and G available to order, and the J option means no bracket is supplied - add a bracket variant if you want panel or surface fixing. The K check valve is worth specifying whenever losing supply would let downstream pressure bleed away.
One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated number, so we cannot quote you a rated flow figure. Send us your line size, inlet pressure and required downstream flow, and we will confirm the right size against the datasheet on request before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves in the catalogue, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Tell us your inlet pressure, downstream set point and the flow your circuit needs, and we will confirm the sizing against the datasheet on request before you order.
The L is the low-pressure type code: this regulator's adjustment range runs up to 0.4 MPa instead of the standard GR range. It is the right choice for circuits that must never see more than 0.4 MPa downstream. Maximum inlet pressure is still 1.0 MPa (145 psi), and if you need set points above 0.4 MPa, the standard-type GR200 is the variant to order.
