The AirTAC GFR20008LJNTK 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 GFR20008LJNTK is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/4 in NPT port, the low-pressure regulator type, a 40 um filter element, a differential-pressure drain and an integral reverse (check) valve. No gauge is fitted and no mounting bracket is included, and the bowl on this 200 size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for drain type, 5 um filtration (code W), gauge and thread (PT standard, G or NPT to order). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet 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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| N | No pressure gauge (N). |
| (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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Filtered, regulated air to clamp cylinders on a CNC fixture, with the fitted check valve holding the downstream circuit against upstream pressure loss.
Clean, moisture-reduced air at a stable setpoint for the gripper cylinders of a robotic pick-and-place cell, prepared at the point of use.
Point-of-use air preparation for diverting and sealing cylinders on a carton packaging line, with the low-pressure type suiting circuits set below standard line pressure.
Start from the port step: this 200 size carries a 1/4 in NPT port, while the larger 300/400/600 sizes step up toward 1/2 in and beyond, so match the size to the air demand of the circuit. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. The low-pressure regulator type (code L) is intended for circuits that hold a lower downstream setpoint than the standard type; its exact adjustment range is not published, so confirm it with us.
The remaining decodable choices: drain type (differential-pressure here; automatic or manual available), filter grade (40 um standard; 5 um with code W), gauge and scale (none fitted here; embedded square or external round gauge with MPa, psi or bar scales on other variants), thread (PT is the standard; G and NPT are order options), and bracket (not included with the J code).
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so no flow number is quoted here. Send us your air demand and line conditions and we will confirm the sizing from the datasheet before you order.
The L code marks the low-pressure regulator variant, intended for circuits that hold a lower downstream setpoint than the standard type. Its exact adjustment range is not published in the catalogue, so confirm the range with us against your setpoint. Everything else decodes normally: NPT1/4 port, 40 um element, differential-pressure drain and a fitted check valve.
