The AirTAC GFR60020MLC2 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 AirTAC GFR60020MLC2 is a size 600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air at the 40 um standard grade, then regulates downstream pressure, with the low-pressure type regulator for circuits that run at reduced set pressures. This configuration has a 3/4 in PT port, a manual drain on the bowl, an external round pressure gauge with a psi scale, and a mounting bracket included. The size 600 bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating 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, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard; G and NPT as order options) and bracket. Flow is published as curves rather than a single rated figure, 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.

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.

Point-of-use preparation on a 3/4 in air drop feeding a mechanical stamping press, filtering line water and scale and holding a low set pressure for the clutch and counterbalance circuits. The manual drain suits a press cell with a scheduled maintenance round.
Feeding the cylinder banks on a bottling hall conveyor system, where the 3/4 in port matches the main branch line and the low-pressure type regulator holds the gentle set pressures the gate and pusher actuators need. The psi gauge lets line staff check settings at a glance.
Mounted in the service panel of a weaving or spinning machine, filtering the mill's compressed air supply and regulating it down for the machine's pneumatic functions. The included bracket fixes the unit to the panel and the manual drain is emptied during shift cleaning.
Start with the port step: this unit is size 600 with a 3/4 in PT port, the largest step in the GFR range, so match it to your line size and the flow your application needs. Drain type is a real choice: this unit has a manual drain, which suits installations where an operator can bleed the bowl on a routine; automatic and differential-pressure drains are available on other configurations if you cannot rely on manual attention. Filter grade is the 40 um standard here; specify the W option (5 um) only where finer particulate removal is genuinely required. The gauge on this unit is the external round type with a psi scale; embedded square gauges and MPa or bar scales are the other options. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your application details and we will confirm the sizing and datasheet figures before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet on request before you order.
The M in the code selects a manual drain: condensate collected in the bowl is released by hand, which suits installations with a regular maintenance routine; automatic and differential-pressure drains are available on other GFR configurations. The L in the code marks the low-pressure type regulator, intended for circuits that run at reduced set pressures; its exact adjustment range is not published in the catalogue, so ask us to confirm it on request.
