The AirTAC GFR60020MJC2K AirTAC Filter Regulator PT3/4, 40 um 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 GFR60020MJC2K is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in PT port, a manual drain bowl in aluminium alloy (the 600 size bowl material), a 40 um standard filter element, a round pressure gauge reading in psi, and a built-in reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 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 family is available in sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, PT, G or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um (W) filtration, gauge and scale choices, and a low-pressure regulator type. Flow is published as curves rather than a single rated figure, so we confirm datasheet figures 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.

|---|---|
| 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. |
| 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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.

Clean, regulated air ahead of a directional-valve manifold on a machine's actuation circuit, with the check valve holding downstream pressure if supply dips.
Filtering and regulating shop air feeding tool-change cylinders and clamping fixtures on a machining centre, with the psi gauge giving operators a direct setpoint readout.
Conditioning the 3/4 in main drop feeding gripper and sealing cylinders on a packaging line, with manual drain fitted into a daily start-up check routine.
Size and port set the capacity envelope: this unit steps up to size 600 with a 3/4 in PT port, the right choice when the line demand sits above what a 300/400 unit at 1/2 in serves - match the size step to the flow your circuit needs. Drain type matters: manual drain means an operator opens the bowl drain periodically, so choose it where checks are already scheduled, and pick automatic or differential-pressure drain where the unit runs unattended. Filtration grade is 40 um standard; specify the W variant for 5 um where finer protection is required. Gauge options are the embedded square gauge (MPa, psi or bar scales) or an external round gauge - this code carries a round gauge on psi. Thread is PT as standard with G (BSPP) and NPT as order options, and the J code here means no mounting bracket is supplied. Flow is published as curves, not a single rating, 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. 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, not as a single rated figure, so we do not quote a number. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code selects a manual drain: condensate collects in the bowl until an operator opens the drain, which suits lines with scheduled maintenance rounds. The K code fits a reverse/check valve, which helps hold the regulated downstream pressure if the upstream supply is interrupted. Automatic or differential-pressure drain variants are available if unattended draining is preferred.
