The AirTAC GFR60020 AirTAC Filter Regulator 3/4 in NPT, 5 um 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 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 AirTAC GFR60020 is a size-600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is built for a 3/4 in NPT port on the larger 600 frame, with the fine 5 um filter element (W) instead of the standard 40 um, a differential-pressure drain on the bowl, and the low-pressure regulator type (L) for circuits that run below standard line pressures. The bowl on the 600 size is aluminium alloy, an embedded square gauge with MPa scale is fitted, and a reverse/check valve (K) is included. No mounting bracket is supplied 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 in to 1 in, and options for thread type (PT standard, G and NPT to order), drain type, filter grade, gauge style and scale, reverse valve and bracket. 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.

| (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). |
| F | Gauge shape: Square. 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. |
| 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.

Feeds a packaging line's manifold with filtered, regulated air at reduced pressure, with the 5 um element keeping water and fine particulate out of the distribution piping and the square gauge giving the operator a set-point reference.
Sits upstream of pneumatic valve actuators and positioners on a process skid, filtering the supply to 5 um and holding a low regulated pressure, with the reverse/check valve helping hold the downstream circuit if upstream supply dips.
Provides filtered, low-pressure regulated air to bench and pilot-plant test rigs where instruments and small actuators need clean air at a stable, reduced pressure and the 3/4 in NPT connection matches the rig's supply header.
Step up or down through the 200/300/400/600 size ladder to match the port and the flow your line needs; this code is the 600 size on a 3/4 in NPT thread. Choose the filter grade to suit the circuit: 40 um is the standard element, while this unit carries the 5 um (W) element for finer particulate and water removal ahead of sensitive downstream components. Drain type is a real choice on GFR units - differential-pressure (as fitted here), automatic (A) or manual (M) - and the drain type affects the standard regulator adjustment range, so confirm the figure for your configuration with us. Gauge style and scale (square MPa as fitted here, with psi or bar scales and an external round gauge as options), the reverse/check valve, bracket and thread family (PT standard, G or NPT) are all decodable from the code. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
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 GFR series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your inlet pressure, set pressure and the flow your circuit needs, and we will confirm the sizing against the datasheet curves for this exact configuration before you order.
The L in the code marks the low-pressure regulator type, intended for circuits that run below standard line pressures. The exact adjustment range for the low-pressure version is not published in our data, so we confirm it on request; the maximum inlet pressure remains 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
