The AirTAC GFR60020LJC2W AirTAC Filter Regulator PT3/4, 5 um 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 PT3/4" 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 AirTAC GFR60020LJC2W is a GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates its pressure downstream. This size-600 unit has PT3/4 ports, a 5 um filter element (code W, against the 40 um standard), a differential-pressure drain on the bowl, and the low-pressure (L) regulator variant. It comes with an external round gauge reading in psi, and no mounting bracket. The bowl on this largest size is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um or 5 um elements, standard or low-pressure regulation, gauge and thread options (PT standard; G and NPT to order). Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.
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, moisture-reduced air held at a steady low pressure feeding paint guns and air-assisted applicators in a body-shop spray booth, with the 5 um element guarding the gun's fine passages.
Low-pressure regulated air for dilute-phase transfer of flour, sugar or spice powder along a conveying line, where the differential-pressure drain keeps free water out of the product zone.
Steady low-pressure air supply to air-operated double-diaphragm pumps on a treatment skid, with the filter section protecting the pump's air valve from grit and condensate.
Size and port step up together: 200, 300, 400 and 600 cover ports from 1/8 to 1 inch, so pick the step that matches your line's air demand - for this model that is size 600 with PT3/4 ports. The choices decoded in this code are all real catalogue options: a 5 um element instead of the 40 um standard for finer particulate control, a differential-pressure drain (the default; automatic and manual are alternatives), the low-pressure L regulator, a round psi gauge, PT thread (G or NPT to order) and no bracket. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line's air demand and we will confirm the right size from the datasheet on request before you order.
L marks the low-pressure regulator variant, chosen where the downstream setpoint sits below the standard band. The exact setting range for the low-pressure type is not published in the material we hold, so we confirm it from the datasheet on request; standard-type GFR units with differential-pressure drain cover 0.15-0.9 MPa (20-130 psi).
