The AirTAC GFR60020MLJF2K AirTAC Filter Regulator 3/4in PT 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 GFR60020MLJF2K is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the largest G-series size with a PT3/4 (3/4 in) port, a manual drain for emptying the bowl by hand, the standard 40 um filter element, a low-pressure regulator type, a reverse/check valve fitted, and an embedded square gauge reading in psi. The 600-size bowl is aluminium alloy, and this unit is ordered without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge and scale options, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so contact 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| (blank) | PT 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.

Feeding filtered, pressure-controlled air to a spray booth's air make-up panel, where the 3/4 in port matches the main drop and the low-pressure regulator holds a gentle set point for coating consistency.
Conditioning the supply air on a carton-sealing or wrapping line: the 40 um element keeps water and debris out of valve manifolds while the regulator sets the pressure the machine's cylinders were designed for.
Serving as the panel-mounted conditioning stage ahead of a distribution manifold in a plant air circuit, with the square psi gauge giving operators a local reading and the manual drain emptied during rounds.
Start with the port step: this unit is size 600 with a PT3/4 port, the largest step in the G-series, so match it to your line's nominal pipe size and required air demand. The manual drain suits installations where an operator can bleed the bowl on a routine; choose automatic or differential-pressure drain codes if the unit will sit unattended. The 40 um element is the standard grade for general air preparation; the 5 um grade (code W) is the finer option. The gauge here is the embedded square type with a psi scale (MPa and bar scales are alternatives), and the low-pressure regulator type is intended for lower set-point work. Thread is PT as standard, with G (BSPP) and NPT available to order; a bracket is optional.
Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering - we will check the datasheet with you.
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 family as performance curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and air demand, and we will confirm the datasheet flow figures for this exact model on request.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl is released by hand. If the unit will run unattended, the differential-pressure drain (blank code) or automatic drain (code A) variants of the same GFR600 filter regulator can be ordered instead.
