The AirTAC GFR600-20MLJF2G AirTAC Filter Regulator G3/4 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20MLJF2G is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/4 (BSPP) port, a manual drain bowl in aluminium alloy, a 40 um standard filter element, a low-pressure regulator type, and an embedded square gauge reading in psi. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", optional 5 um filtration (code W), automatic or differential-pressure drains, G or NPT thread options, and gauge scale choices. Flow figures are published as curves rather than a single rating, so we confirm the datasheet and sizing 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |
| (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.

Filtering and regulating the supply air feeding pneumatic presses and clamping fixtures on a stamping line, with the low-pressure regulator holding a gentle setpoint for sensitive actuator circuits.
Conditioning air ahead of the filler and capper valve manifolds on a beverage bottling line, where the manual drain lets the maintenance team bleed accumulated condensate at each shift check.
Serving as the point-of-use filter regulator on the air preparation panel of a CNC machining center, protecting tool-change cylinders and air bearings from water and scale in the shop supply.
Step up through sizes 200, 300, 400 and 600 as your port and air demand grow; this unit sits at the top of the range with a G3/4 port. Drain choice matters: manual means someone opens the drain regularly, while automatic and differential-pressure drains discharge condensate without attention. The 40 um element is the standard grade; specify 5 um (code W) where finer particle removal is needed. Gauges are available in MPa, psi or bar scales, and this code carries the square gauge in psi. Thread is G (BSPP) here, with PT standard and G/NPT as order options; brackets are optional. Flow 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. Tell us your line pressure, set pressure and expected air demand and we will confirm the sizing against the datasheet curves on request before you order.
This code has a manual drain: condensate collects in the aluminium bowl until an operator opens the drain, which suits attended installations on regular maintenance rounds. If the unit will run unattended, ask about the same size with an automatic or differential-pressure drain instead.
