The AirTAC GFR60020LC1T 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 AirTAC GFR60020LC1T is a 600-size GFR filter regulator: one body that first removes water and particulate from compressed air, then regulates downstream pressure. This configuration carries a 3/4 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as pressure differential builds, and a fitted round pressure gauge reading in MPa. It is the low-pressure type, intended where controlled pressures sit below the standard regulator band, and the aluminium alloy bowl suits this largest 600 frame. 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 range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include a 5 um element (code W), manual or automatic drain, square or round gauges with MPa, psi or bar scales, G or NPT threads in place of the PT standard, and a reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Filter and regulate the air feeding a bank of directional control valves on a 3/4 in main, keeping moisture and pipe scale out of the valve spools while holding a steady, reduced pressure to the manifold.
Condition the branch line serving big-bore air cylinders and clamps on a production machine, where the 600 frame and 3/4 in port match the heavier air demand of the drop.
Serve a low-pressure pneumatic circuit, such as a material-handling or actuated-gate loop, where the low-pressure regulator type and a visible MPa gauge let operators set and monitor the working pressure directly.
Work through the decodable choices in order. Size 600 with a 3/4 in NPT port is the largest GFR frame, so step up to it when your line's flow demand outgrows a 300 or 400; step down when it does not. Drain: this unit uses the differential-pressure drain (the default), which needs no daily attention; choose automatic (A) for unattended condensate handling or manual (M) where you want deliberate, scheduled draining. Filter grade: the standard 40 um element suits general plant air; specify the W code for 5 um where downstream equipment needs finer protection. Gauge: this code carries a round external gauge on an MPa scale; square embedded gauges and psi or bar scales are alternatives. Thread: NPT here, with PT standard and G (BSPP) as order options. A mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your application parameters 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 flow for this series as performance curves, not as a single rated number, so we do not quote a flow figure here. Tell us your line pressure, set pressure and air demand, and we will confirm the sizing from the datasheet curves on request before you order.
This unit's differential-pressure drain releases collected condensate automatically whenever the pressure differential across the drain reaches its trigger point, so it suits lines with steady, regular airflow. If the line runs intermittently or unattended, the automatic drain (code A) is the better choice; if you prefer deliberate, scheduled draining, order the manual drain (code M).
