The AirTAC GFR600-20T AirTAC Filter Regulator, NPT3/4, psi Gauge 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 GFR600-20T is a size-600 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is threaded 3/4 in NPT, carries the standard 40 um filter element, and has a manual drain, so condensate is released by opening the drain fitting by hand. Because this is the 600 size, the bowl is aluminium alloy, and the unit is supplied with the embedded square pressure gauge scaled in psi. A reverse (check) valve is fitted, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or differential-pressure drains, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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)). |
| (blank) | Standard 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 3/4 in main drop feeding a carton-sealing and wrapping line, it removes water and pipe scale from the compressed air and holds a steady regulated pressure to the line's directional valves, with the psi gauge giving operators a setpoint at a glance.
Mounted ahead of a bench-mounted pneumatic press or clamp fixture, it filters incoming shop air and lets the setter dial in the working pressure that the tooling was designed for, with the check valve holding the downstream setting if supply pressure dips.
Used on the air feed to a laboratory test rig or pilot-scale process skid, it strips condensate and particulate from the facility supply and provides a manually adjustable, gauge-monitored pressure for instruments and air-actuated valves.
Size the unit by port and required flow: this 3/4 in NPT, size-600 body is the largest step in the GFR range, and flow capacity is published as curves, not a single rating, so send us your demand and we will confirm the fit. Choose the drain to match the installation: manual (this unit) suits attended installations, automatic drain suits unattended drops, and differential-pressure drain bleeds with the pressure differential. Filtration is 40 um standard; specify code W for 5 um where finer protection is needed. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread; G (BSPP) and NPT are orderable options, as NPT is here. Brackets are optional (this unit has none).
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 there is no one number we can honestly quote. Tell us your line pressure, set pressure and air demand, and we will confirm the sizing against the datasheet curves before you order.
The M in the code GFR60020MJF2TK specifies a manual drain: condensate collects in the aluminium bowl and is released by opening the drain fitting by hand, which suits installations that are checked regularly. Automatic (code A) and differential-pressure (blank) drains are available on the same series if you prefer unattended condensate removal.
