The AirTAC AirTAC GFR600-20 Filter Regulator 3/4" NPT, 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 GFR600-20 is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This size 600 unit is specified with a 3/4 in NPT port, a manual drain bowl in aluminium alloy, a 40 um standard filter element, and a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). An embedded square gauge with a psi scale is fitted so the set pressure is readable at the unit, and no mounting bracket or reverse/check valve is included in this configuration.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and can be ordered with PT, G (BSPP) or NPT threads, manual, automatic or differential-pressure drains, a 5 um (code W) element, MPa/psi/bar gauge scales, and a bracket where needed. Rated flow for this family is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures for your application 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. 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. |
| (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.

Drops feeding a packaging hall's pneumatic actuators get one unit that strips water and debris from the main line and holds a steady working pressure, with the psi gauge letting the shift engineer read and verify the set point.
On a conveyor line with pneumatically operated gates and diverters, this 3/4 in filter regulator conditions the branch supply and keeps cylinder pressure constant so sorting actions stay repeatable through the shift.
A maintenance workshop running impact wrenches, grinders and clamping fixtures from a 3/4 in drop benefits from clean, regulated air at the bench, with the manual drain bled down as part of the daily close-up routine.
Size and port are the first decision: the 600 size steps up to a 3/4 in port for higher air demand, and you should match the port step to the flow your line needs. For this unit the drain is manual, which suits installations where an operator can bleed the bowl on a routine; automatic or differential-pressure drains are available if unattended water removal matters. The 40 um element is the standard grade, with a 5 um (W) element offered where finer filtration is required. The fitted square gauge reads in psi, and MPa or bar scales are alternatives. Threads are PT as the catalogue standard, with G (BSPP) and NPT as orderable options - this unit is the NPT version - and a bracket is optional (not fitted here). Flow for the GFR series is published as curves, not a single rating, so send us your demand figures and we will confirm sizing against the datasheet before you order.
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 rather than a single rated figure, so we do not quote a rated flow number for this unit. Tell us your air demand and line pressure and we will confirm the datasheet flow curve and sizing for your application on request.
This GFR600-20 is ordered with a manual drain: an operator opens the bowl drain to expel collected water. The GFR family also offers an automatic drain (code A) and a differential-pressure drain (the default, blank code) where you want water removal without manual attention - both are orderable options on the same size 600 body.
