The AirTAC GFR60020LC2K AirTAC Filter Regulator PT3/4 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 GFR60020LC2K is a GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body with 3/4 inch PT ports. This configuration carries the standard 40 um filter element, a differential-pressure drain that bleeds accumulated condensate automatically as the pressure differential across the element rises, and the low-pressure regulator type for applications that work at reduced supply pressures. It is fitted with an external round gauge reading in psi, a reverse (check) valve to hold downstream pressure when the upstream supply is lost, and a mounting bracket. Because this is size 600, the drain bowl is aluminium alloy rather than the polycarbonate used on the smaller 200/300/400 sizes.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options including automatic or manual drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads, and bracketless versions. 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.

On a bottling or canning hall's main air drop, this 3/4 inch filter regulator cleans the compressed air of water and pipe scale and holds a steady reduced pressure to the hall's pneumatic distribution headers, with the check valve holding the downstream line if the compressor room trips.
Sorting and accumulation conveyors use air cylinders for stoppers, pushers and gate diverters. This unit filters the supply feeding those valve manifolds and regulates it to the pressure the cylinders were designed for, with the psi gauge giving operators a visible setpoint.
A process pilot plant or test rig running low-pressure air duties - sparging, purging, actuating sample valves - needs clean, steadily regulated air at modest pressures. The low-pressure regulator type, 40 um filtration and differential-pressure drain suit an unattended rig running long campaigns.
Start with the port step: this unit is size 600 with a 3/4 inch PT port, the largest in the GFR range, so step down to 300 or 400 if your line runs smaller ports and lower air demand. Drain choice matters: the differential-pressure drain fitted here needs no operator attention, but a manual-drain (M) version suits installations where you prefer scheduled draining, and an automatic drain (A) suits high-condensate duty. The 40 um element is standard; specify the W code if you need the 5 um grade. The round psi gauge fitted here is one option - embedded square gauges are standard, and MPa or bar scales can be ordered. Threads are PT as standard with G (BSPP) and NPT as order options, and this version includes the mounting bracket. 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. 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 rather than a single rated figure, so we do not quote a rated flow number for this unit. Send us your application - port size, demand and working pressure - and we will confirm the flow data from the datasheet so you can size it correctly before ordering.
The differential-pressure drain is the standard GFR drain: it discharges condensate from the bowl automatically as the filter element loads up, with no operator input. If your duty is better served by an automatic drain (code A) or a manual drain (code M), those are orderable options in the same size - note that the drain type affects the regulator's adjustment range, so tell us which you need when you enquire.
