The AirTAC GFR60020MJC3T AirTAC Filter Regulator 3/4 in NPT 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 GFR60020MJC3T is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point in a single body. This size 600 unit has a 3/4 in NPT port, a manual-drain bowl in aluminium alloy, a 40 um filter element, and a round pressure gauge reading in bar. The manual drain means an operator opens the drain valve to release collected condensate, so it suits installations that are checked on a regular schedule. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range on this manual-drain version is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), a 40 um standard or 5 um (W) element, gauge and thread options, and an optional mounting bracket. Flow for the series is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet against your application.

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). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Feeding spray booths and paint guns from a shop air main: the unit strips water and pipe-scale from the supply and holds the pressure setting the painter has dialled in, so finish quality does not drift as the main pressure moves. The manual drain suits a booth checked at the start of every shift.
Conditioning the air feeding tool changers, clamps and air-blow nozzles on a machining center: particulate and condensate are taken out before they reach the valves, and the regulator holds a steady set point for the clamping circuit. The 3/4 in port suits a machine-level drop fed from a larger main.
Supplying the cylinder- and valve-driven stations on a bottling or packaging line: clean, regulated air keeps the fill, capping and transfer stations repeating their stroke consistently through the shift. The manual drain bowl in aluminium alloy is emptied during scheduled line cleaning.
Size and port step up with flow demand: this is the largest GFR size, 600, with a 3/4 in NPT port, chosen when line flow is beyond what the 200-400 sizes handle. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The M code sets a manual drain - choose A for an automatic drain, or leave the position blank for the differential-pressure drain, if your installation is not checked regularly. The 40 um element is standard; specify W for 5 um filtration. This unit is supplied as coded with a round bar-scale gauge (C3), no mounting bracket (J), and NPT thread (T); G (BSPP) and PT are the other catalogue thread options.
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 here. Send us your line pressure, downstream demand and application details, and we will confirm the flow and sizing from the datasheet on request before you order.
The M in the code sets a manual drain: condensate collected in the aluminium bowl is released by opening the drain valve during scheduled checks. If your installation is not checked regularly, order the A code for an automatic drain or leave the position blank for the differential-pressure drain. The 40 um element is standard on this model; the W code gives 5 um filtration.
