The AirTAC GFR60020ALJF2G AirTAC Filter Regulator G3/4 Auto Drain 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 automatic 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 GFR60020ALJF2G is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a G3/4 port, an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, and a low-pressure regulator type for circuits that operate below standard regulating ranges. The embedded square gauge is fitted with a psi scale, and the size-600 bowl 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 is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um (W) filter grades, gauge scales in MPa, psi or bar, and G or NPT thread options to order. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic 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). |
| F | Gauge shape: Square. 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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

Supplies filtered, regulated air to fixture clamps that must hold at a controlled low pressure, with the automatic drain keeping condensate out of the clamp cylinders between cycles.
Feeds bottle-gripping and transfer actuators on a filling line, where the 40 um element protects valve spools and the automatic drain handles condensate from a long air main.
Regulates supply to diverter gates and stoppers on a packaging conveyor, with the psi-scaled square gauge letting line staff verify setpoints at a glance.
Start with the port step: this unit is size 600 with a G3/4 port, the largest in the GFR range - step down to 200/300/400 if your line uses smaller ports and lower air demand. The automatic drain suits installations that are not checked daily; choose manual drain where an operator drains the bowl routinely, or the differential-pressure default where drain should follow load. The 40 um element is the standard grade; specify the W code for 5 um where finer particulate removal is needed. This unit carries the L (low-pressure) regulator type, so confirm your regulated setpoint suits a low-pressure type - we can confirm the exact regulating range on request. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP); PT is the standard thread and G/NPT are order options. A mounting bracket is not fitted with the J code. 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 the GFR600 as performance curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow data from the datasheet and check the sizing against your demand before you order.
The A in the code means the bowl drains collected condensate automatically, so no manual draining routine is needed. This unit also carries the L (low-pressure) regulator type; its exact regulating range is not published in the material we hold, so ask us to confirm it from the datasheet for your setpoint.
