The AirTAC GFR60020MLC2TK AirTAC Filter Regulator NPT 3/4 in 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 GFR60020MLC2TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body, so one component handles both air preparation jobs. This configuration carries a 3/4 in NPT port, a manual drain bowl in aluminium alloy, the standard 40 um filter element, and a low-pressure regulator type for circuits that run below standard working pressures. It is fitted with an external round gauge scaled in psi, a reverse/check valve to hold downstream pressure, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 sizes from 1/8 in to 1 in, with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and standard or low-pressure regulation. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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. |

| 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. |

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.

On an assembly-line fixture where clamp cylinders are held at reduced pressure to avoid marking delicate workpieces, this filter regulator cleans the supply and holds the set pressure, with the psi gauge giving operators a direct reading at the cell.
Instrument and valve-positioner air in a process plant must be clean and steady; this unit filters the line and regulates the pilot pressure, while the reverse/check valve helps hold the downstream pressure if the main supply dips.
Heat-seal and forming stations on a packaging line run on low-pressure air; this size-600 unit mounted on its bracket at the machine drop filters condensate and particulate from the 3/4 in supply and sets the pressure the sealing cylinders need.
Start with the size and port: the 600 series is the largest GFR frame, and this unit's 3/4 in NPT port should match the line size your flow demand requires - step up or down a size if your circuit needs more or less air. The manual drain on this unit means an operator or maintenance routine opens the bowl drain to remove collected condensate; if nobody is on site regularly, consider the automatic or differential-pressure drain versions instead. The 40 um element is the standard grade; specify the W option for 5 um where finer protection is needed. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives. PT is the standard thread, with G (BSPP) and NPT as order options, and the bracket is included. 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 this series as performance curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow data from the datasheet and check the sizing for you on request.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl is emptied by opening the drain by hand as part of a maintenance routine. If the unit will be installed where no one drains it regularly, the automatic or differential-pressure drain versions are the better choice - ask us about those variants.
