The AirTAC GFR60020MLF2TK AirTAC Filter Regulator NPT3/4 Low-Pressure 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 is a filter regulator: it removes water and particulate from compressed air and reduces pressure in a single body. This 600-size unit is fitted with a 3/4 in NPT port, a manual drain and a 40 um filter element, and its regulator is the low-pressure type. An embedded square gauge reading in psi and a reverse (check) valve are included, the 600-size bowl is aluminium alloy, and a mounting bracket is supplied.
This is a genuine AirTAC part. The GFR range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, plus options for automatic or differential-pressure drains, a 5 um element, alternative gauge scales, and G or NPT threads in place of the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for 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. 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.

| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| 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. |

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 filtered, regulated air to the tool-changer and clamping valves of a CNC machining center, with the manual drain emptied during shift checks and the psi gauge set at the panel.
Supplying carton-sealing and case-erector cylinders on a packaging line, where the filter catches water and pipe scale and the low-pressure regulator holds a reduced setting for the machine's actuators.
Reducing supply pressure for air-driven spray equipment in a coating booth, with the 40 um element protecting the gun from moisture and debris carried in the shop air.
Size and port set the air capacity: this unit is size 600 with a 3/4 in NPT port, the largest step in the range, so match the port to your supply line and required flow. Drain type matters: the manual drain here must be opened by hand to empty the bowl, while automatic and differential-pressure drains discharge condensate without attention. The 40 um element is the standard grade; a 5 um element (code W) is available when finer filtration is needed. The embedded square gauge reads in psi, with MPa and bar scales and an external round gauge as alternatives. G and NPT threads are order options against the PT standard, and the included bracket simplifies mounting. Because flow is published as curves rather than a single rating, 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 rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the flow and datasheet figures for this 3/4 in unit on request.
The M in the code specifies a manual drain: condensate collects in the aluminium bowl and is emptied by opening the drain by hand, so it suits attended installations on a regular check routine. The L specifies the low-pressure regulator type, intended for reduced-pressure settings; its exact adjustment range is not published, so ask us to confirm it against your setpoint. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature is -5 to 70 C, non-freezing.
