The AirTAC GFR60020LJC2T AirTAC Filter Regulator NPT 3/4 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 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 GFR60020LJC2T is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This size 600 unit carries a 3/4 in NPT thread, is built as the low-pressure type, and drains condensate automatically by differential pressure - no manual draining routine is needed under normal operation. Filtration is the 40 um standard grade, and the fitted external round gauge reads in psi so line pressure can be checked and set at a glance.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in up to 1 in, drain, filter-grade, gauge, bracket and thread options to match. We confirm flow and other datasheet figures for this exact model on request - flow is published as curves rather than a single rating.

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. |
| (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. |
| (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.

Installed at the drop from a 3/4 in plant air main, the unit strips water and swarf-carrying particulate and holds a steady low regulated pressure to the cell's pneumatic valves and actuators, with the psi gauge giving operators a visible line-pressure check.
Feeding the air cylinders that raise, stop and divert product on a packaging conveyor, the filter regulator keeps moisture out of the valve stack and lets the line set the lower working pressure the gate cylinders were designed for.
Mounted at the inlet of a control panel that feeds positioners, transmitters and small actuated valves, the unit conditions the instrument air supply and regulates it down to the low setpoint the panel components require, with differential-pressure draining keeping the bowl clear between service visits.
Size 600 is the largest step in the GFR range, with a 3/4 in port, so start there when the line demands higher flow; step down to 300 or 400 where demand is lighter. Drain is differential-pressure on this unit, which suits installations you do not want to visit for manual draining; a manual-drain version exists if you prefer positive control. The 40 um standard grade covers general plant air - choose the 5 um (W) option only where downstream equipment needs finer filtration.
The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread here is NPT - PT is the standard and G (BSPP) is also an order option. No mounting bracket is fitted on this code (J). Flow for sizing is published as curves, not a single rating, so 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 the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet curves for this exact model on request.
The L in the code marks the low-pressure regulator type, intended where the regulated setpoint sits below what the standard type covers; the exact range for this variant is not published in our sheet, so ask us to confirm it for your setpoint. Drain is differential-pressure: condensate is expelled automatically whenever the pressure differential across the filter element is sufficient, so no manual draining is required.
