The AirTAC GFR600-20MLJC1WT AirTAC Filter Regulator NPT3/4 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 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 GFR600-20MLJC1WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single 600-size body with a 3/4 in NPT port. This configuration carries the 5 um filter element (code W) for finer filtration than the 40 um standard, a manual drain for the aluminium alloy bowl, the low-pressure regulator type, and a round external pressure gauge scaled in MPa. No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT to order) and bracket. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures on request before you order.

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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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 ahead of a directional-valve manifold on a machine's air preparation line, it cleans the supply through the 5 um element and holds the manifold pressure steady at the low setpoint the circuit requires.
On a packaging line running pneumatic clamp and pusher cylinders, the unit filters condensed water and particles from the plant air and lets the line operator dial in and read the working pressure on the MPa gauge.
Fitted at a shop air drop feeding hand tools and test fixtures, it gives the technician filtered air with a manually drained aluminium bowl and an adjustable, gauge-read pressure setting for the task at hand.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start there when the line demands the highest flow capacity, and step down to 300/400 where the circuit is smaller. This unit has a manual drain, which suits installations where an operator can bleed the bowl on a routine; choose automatic or differential-pressure drain codes if the bowl cannot be attended. The 5 um element (W) is the right pick when downstream valves and cylinders need finer protection than the 40 um standard. The gauge here is the external round type on the MPa scale; square embedded gauges and psi or bar scales are alternatives. Thread is NPT on this code; PT is the catalogue standard and G is also orderable. No bracket is fitted (code J), so plan a rigid pipe connection or add a bracket variant.
Flow for this series is published as curves, not a single rated figure, 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 GFR series flow as performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and datasheet figures for this 3/4 in, 600-size unit on request before you order.
In the code GFR60020MLJC1WT, M sets the manual drain (you bleed the bowl by hand instead of relying on an automatic mechanism), C specifies the external round gauge, and 1 sets its scale to MPa. If you prefer hands-off drainage, an embedded square gauge, or a psi or bar scale, those are alternative orderable codes in the same series.
