The AirTAC GFR60020ALF1WT AirTAC Filter Regulator NPT3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020ALF1WT is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a 3/4 in NPT port for larger supply lines, a 5 um filter element (code W) for finer air cleaning than the standard 40 um grade, and an automatic drain that expels collected condensate without manual attention. The regulator is the low-pressure type, and an embedded square gauge scaled in MPa is fitted so the downstream setting can be read at a glance. The bowl on this size is aluminium alloy, and a mounting bracket is included. 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 spans sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drains, 40 um or 5 um elements, standard or low-pressure regulators, square or external round gauges with MPa, psi or bar scales, G (BSPP) or NPT thread options, and bracket or no-bracket variants. 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.

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.

Cleaning and regulating the shop-air feed to impact wrenches and nutrunners at assembly stations, with the automatic drain keeping condensate out of the drop leg during long shifts.
Supplying filtered, steady low-pressure air to film-sealing and clamping cylinders on a wrapper or cartoner, where the low-pressure regulator type suits modest set pressures and the MPa gauge shows the setting.
Conditioning the compressed air feeding pneumatic actuators on lab analysers and sample-handling equipment, with the 5 um element protecting fine valves from particulate carryover.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest size in the GFR range - step down to 200/300/400 (1/8 to 1/2 in) if your line is smaller, but match the size to the flow your circuit needs. Drain choice matters: automatic (this unit) drains itself, manual needs an operator, and the differential-pressure default drains only when the pressure differential builds. Element grade is 5 um here versus the 40 um standard - choose 5 um where downstream equipment is sensitive to finer particles. The fitted square gauge reads in MPa; psi and bar scales and an external round gauge are available. Thread is NPT here; PT is the standard catalogue thread and G (BSPP) is also offered. A bracket is included (code J would omit 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or l/min number. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request.
The L in GFR60020ALF1WT marks the low-pressure regulator variant, intended for applications set below the standard regulator's range. The exact adjustment range for the low-pressure type is not published in the material we hold, so ask us to confirm it on request. The standard GFR range and the automatic drain, 5 um element, square MPa gauge, aluminium alloy bowl and included bracket on this unit are all as decoded from the catalogue.
