The AirTAC GFR60020ALF1TK 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 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 GFR60020ALF1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This size 600 unit carries a 3/4 in NPT thread, an automatic drain that expels collected condensate without operator attention, a 40 um standard filter element, and the low-pressure regulator type (contact us for the exact adjustment range of this variant). It is fitted with an embedded square pressure gauge scaled in MPa and a reverse/check valve, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the bowl is aluminium alloy, the standard material at size 600.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT thread alternatives to the PT standard. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application before ordering.

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 conditioning for a stamping or clamping press: the GFR removes condensate and particles from the shop-air supply, then holds the regulator setpoint for the cylinder circuit, with the automatic drain keeping the aluminium bowl clear through continuous shifts.
On a cartoning or wrapping line, this 3/4 in filter regulator conditions the air feeding conveyor stoppers, pushers and bagging cylinders, protecting seals from water and debris while the MPa gauge lets operators verify line pressure at a glance.
For quarter-turn pneumatic actuators on a water-treatment or chemical dosing skid, the unit filters the supply and regulates actuator pressure, with the reverse/check valve holding the downstream circuit through supply dips and the bracket giving clean panel mounting.
The real, decodable choices on this family: step the size (200/300/400/600) and port (1/8 to 1 in) against the flow your line needs; pick the drain - differential-pressure (default), automatic (this unit) or manual; choose the 40 um standard element or the 5 um option (code W); set the gauge scale to MPa, psi or bar; and select the thread - PT is the standard, with G (BSPP) and NPT as orderable options (this code is NPT). The regulator here is the low-pressure type, so confirm its adjustment range against your setpoint with us. Flow is published as curves, not a single rating - ask us to check the datasheet against your application 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your inlet pressure, set pressure and expected air consumption, and we will confirm the flow from the datasheet for this exact model before you order.
The A in this code selects the automatic drain, which expels condensate from the bowl without operator attention - useful on unattended or continuous-duty installations. The GFR family is also offered with manual (M) or differential-pressure (blank) drains, and a 5 um element (code W) if finer filtration is needed.
