The AirTAC GFR60020LC2TK 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 differential-pressure 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 GFR60020LC2TK is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure as a low-pressure type, with a differential-pressure drain that bleeds accumulated condensate automatically as flow passes through. This configuration is built for 3/4 in NPT ports, carries a maximum inlet pressure of 1.0 MPa (145 psi), and operates from -5 to 70 C (non-freezing). It is fitted with an external round gauge scaled in psi, a reverse/check valve, and a mounting bracket. Because the size-600 bowl is aluminium alloy, the unit suits installations where a polycarbonate bowl is not preferred.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic, manual), a 5 um filter option (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. 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.

Feeding directional control valves that index cartons and close flaps: the 40 um element strips water and pipe scale before they reach the valve spools, while the low-pressure regulator holds a gentle supply pressure suited to small actuator circuits.
Supplying the air cylinders that divert bottles between lanes: filtered, regulated air at a low setpoint keeps gate strokes consistent and protects cylinder seals from condensate carryover, with the psi gauge giving operators a visible setpoint.
Conditioning the supply to low-pressure jets, thread tensioners and clamping devices on weaving and spinning machinery: the aluminium bowl and reverse/check valve suit continuous-duty plant air, and the 3/4 in NPT ports tie into the machine's main drop.
Sizing starts with the port step: this unit is the size-600 body with 3/4 in NPT threads, the largest published GFR size, so match it to your line's pipe size and expected air demand. The low-pressure regulator type (code L) is the decodable choice for circuits that hold a lower regulated pressure than a standard unit targets; its exact adjustment range is not published, so confirm it with us against your setpoint. Drain is differential-pressure by default here; automatic (A) and manual (M) versions exist if your duty cycle or access needs differ. The filter element is the standard 40 um grade, with a 5 um option (W) if downstream equipment needs finer filtration. The gauge in this code is the external round type scaled in psi; embedded square gauges and other scales are alternatives. Thread is NPT as ordered, with PT and G available as catalogue options, and the bracket is included. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing from 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 number, so we do not quote a rated flow, Cv or SCFM figure. Send us your line pressure, downstream demand and setpoint and we will confirm the sizing from the datasheet on request before you order.
In the code GFR60020LC2TK, C selects the external round gauge instead of the embedded square one, 2 sets its scale to psi, and K means a reverse/check valve is fitted on the regulated outlet. L marks the low-pressure regulator type, intended for circuits held at lower regulated pressures; its exact adjustment range is not published, so confirm it with us against your setpoint.
