The AirTAC GFR60020MLF1TK 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 GFR60020MLF1TK is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is built with 3/4 inch NPT ports, a manual drain on the bowl, the standard 40 um filter element, a low-pressure regulator type, an embedded square pressure gauge with MPa scale, and a reverse/check valve fitted. The 600-size bowl is aluminium alloy, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options for drain type, 5 um filtration, gauge style and scale, thread form and reverse valve. Because flow for this series is published as curves rather than a single rating, we confirm the datasheet and sizing 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.

| 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. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |

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 bottling or canning line, this 3/4 inch filter regulator conditions the compressed air feeding rinse blow-off and actuation circuits, removing water and particulate while the low-pressure regulator type holds the reduced pressure the line's valves were set up for.
Large sortation and palletising conveyors use 3/4 inch air feeds to drive diverters, stops and gate cylinders. This unit filters the supply and regulates it downstream, with the manual drain letting maintenance staff bleed accumulated condensate during scheduled rounds.
Spray booths and coating rigs need clean, moisture-free air held at a steady reduced pressure. The 40 um element strips water and debris ahead of the guns, the MPa gauge gives the operator a direct pressure readout, and the check valve prevents backflow into the regulator.
Size 600 with 3/4 inch ports is the largest step in the GFR range, so start there when your line's air demand points to the top of the family; smaller 200/300/400 units cover lighter duties at smaller ports. This configuration carries a manual drain, which suits installations where an operator can bleed the bowl on a routine basis; automatic or differential-pressure drains are available if the unit will sit unattended. The 40 um element is the standard grade, with a 5 um (W-code) element offered where finer particulate removal is needed. The fitted square gauge reads in MPa, with psi or bar scales and an external round gauge available as alternatives. PT is the standard thread; G (BSPP) and NPT are orderable options, and this unit is ordered in NPT. A mounting bracket is included, and the reverse/check valve is fitted on this code. Note that this is the low-pressure regulator type: the exact adjustment range for the low-pressure version is not published in the data we hold, so ask us to confirm it. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
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 l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow and sizing figures from the datasheet on request.
The M in the code specifies a manual drain: an operator opens the bowl drain to release collected condensate. If the unit will be installed where nobody can bleed it regularly, the GFR600 family is also available with automatic (A) or differential-pressure (blank) drains - ask us for those codes.
