AirTAC GFR200-08 Filter Regulator (GFR20008LJNW)
The AirTAC AirTAC GFR200-08 Filter Regulator (GFR20008LJNW) is a genuine G-series filter regulator: water separation, 5 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.

About the AirTAC GFR200-08 Filter Regulator (GFR20008LJNW)
The AirTAC GFR20008LJNW is a genuine AirTAC G-series filter regulator: filtration and pressure regulation combined in a single body, with a drain bowl and no lubricator. This 200-size configuration pairs the W-code 5 um fine filter element with the low-pressure regulator type, adjustable up to 0.4 MPa, on a PT1/4" (Rc) port. The differential-pressure drain clears collected condensate automatically as air flows through, the N code means no gauge is fitted, and the J code means no mounting bracket is included. Medium is compressed air only; maximum inlet pressure is 1.0 MPa (145 psi) and the operating range is -5 to 70 C (non-freezing). The 200-size bowl is polycarbonate (PC).
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes, 1/8" to 1" ports, PT, G (BSPP) and NPT threads, 40 um or 5 um elements, differential-pressure, automatic or manual drains, and gauge or no-gauge builds. Airflow appears in the catalogue only as performance curves rather than a single rated figure, so we will confirm datasheet and sizing numbers for your application on request.

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.
Model Code: AirTAC GFR200-08 Filter Regulator (GFR20008LJNW)
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.
Size Class

- GFR400PT3/8" - PT1/2"
- GFR600PT3/4" - PT1"
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.

Where the AirTAC GFR200-08 Filter Regulator (GFR20008LJNW) Is Used
Clean-air feed to pneumatic sensor and jet circuits
Supplies finely filtered low-pressure air to air-jet sensors, cooling jets and thin pneumatic lines on production equipment where particulate would clog small orifices.
Regulated supply to a pick-and-place gripper
Feeds small gripper and vacuum-assist circuits on a compact pick-and-place module with pressure reduced to a gentle setpoint and air cleaned to 5 um.
Pilot air to process control valves
Conditions the pilot supply to pneumatic positioners and control valves on process skids, keeping moisture and fine particles out of sensitive pilot passages.
Is the AirTAC GFR200-08 Filter Regulator (GFR20008LJNW) the Right Unit?
This build suits circuits that need fine 5 um filtration and low-pressure regulation but already have a gauge on the machine - no duplicate readout at the unit. The 200 frame with a 1/4" PT port is the compact step; select 300, 400 or 600 as required flow grows. The L-type regulator adjusts up to 0.4 MPa; for higher setpoints pick a standard GFR variant, which spans 0.15-0.9 MPa with a differential or automatic drain. Drain here is differential-pressure and self-acting; automatic (A) and manual (M) versions exist if your maintenance routine prefers them. Thread is PT standard, with G (BSPP) and NPT orderable as catalogue options, and no bracket is fitted per the J code. Flow is published only as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR200-08 Filter Regulator (GFR20008LJNW) FAQ
AirTAC does not quote a single rated-flow figure for this model; flow is published as performance curves in the datasheet and varies with supply pressure, setpoint and the 5 um element fitted. Give us your operating pressure and demand and we will confirm the curve-based sizing on request before you order.
This LJNW build has no gauge: it is the same 200-size, 1/4" PT, low-pressure, differential-drain filter regulator with the 5 um element, minus the pressure readout - ideal when the machine panel already shows the pressure. If you want a local display, order the equivalent gauged code with the embedded square gauge in MPa, psi or bar.
