The AirTAC GFR60020MLF3TK AirTAC Low-Pressure Filter Regulator 3/4 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 AirTAC GFR60020MLF3TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the low-pressure type with a 3/4 in NPT port, a manual drain on the bowl, a 40 um standard filter element, an embedded square gauge scaled in bar, and a reverse/check valve fitted. The size-600 bowl is aluminium alloy, and the mounting bracket is included.
This is a genuine AirTAC part from the GFR range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, drain, filter-grade, gauge, thread and check-valve options. Flow figures are published as curves rather than a single rating, 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. 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.
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 a fixture-clamping manifold that works at reduced line pressure, this low-pressure filter regulator cleans the supply, holds the set pressure and prevents backflow when the upstream line is vented.
Feeding cylinders and air grippers on a carton-sealing or case-packing conveyor, the unit strips water and swarf from the shop air and gives operators a bar-scaled setpoint at the machine.
On a bench rig or pilot rig supplied from a shop compressor, the 40 um element and manual-drain aluminium bowl keep test actuators supplied with clean, regulated air at a stable low-pressure setting.
Size and port set the capacity envelope: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range. The drain choice matters in service: manual drain (this unit) means an operator opens the drain when needed, 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 where finer filtration is needed. The square gauge here is scaled in bar, with MPa and psi scales and an external round gauge available as options. Thread is NPT on this unit; PT is the catalogue standard and G (BSPP) is also an order option. A bracket is included; code J would remove it.
Because flow is published as curves and not as a single rated figure, 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 rated flow, Cv or SCFM number. Tell us your application and we will confirm the datasheet flow figures for this size-600, 3/4 in unit on request.
The M in the code specifies a manual drain on the bowl: condensate collects in the aluminium bowl and is released by opening the drain when needed, rather than discharging automatically as with the automatic or differential-pressure drain options. It suits installations that are checked as part of a routine. This unit is also the low-pressure type, fitted with a square bar gauge, a 40 um element and a reverse/check valve.
