The AirTAC AirTAC GFR600C20LC2K Filter Regulator 3/4 in PT 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 See datasheet 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 GFR600C20LC2K is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one 600-size body with a 3/4 in PT port. This configuration is the low-pressure type, fitted with a round psi gauge, a built-in reverse/check valve, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. The 40 um standard element handles everyday workshop air, and because this is the 600 size the bowl is aluminium alloy rather than polycarbonate. A mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 40 um standard or 5 um (W) element, embedded square or external round gauges in MPa, psi or bar scales, PT, G or NPT threads, and standard or low-pressure regulation. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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 bag-sealing or tray-lidding line, the sealing jaws and hold-down clamps often need gentle, steady air rather than full line pressure. This unit strips water and 40 um particulate from the shop supply and regulates it down to the low setpoint the sealer was set up for, with the psi gauge letting an operator verify the setting at a glance.
Sorting gates, stops and diverters on a conveyor run are small cylinders that chatter and wear quickly when fed unregulated air. Placed at the drop for that conveyor section, this filter regulator cleans the supply and holds a stable low pressure so the gates stroke consistently through the shift, while the check valve holds the downstream circuit if upstream pressure dips.
Bench-scale reactors, sample handlers and pilot-plant fixtures frequently use air actuators rated well below the building's 90-100 psi supply. This unit filters the house air and regulates it into the low-pressure band those devices expect, with the differential-pressure drain keeping condensate out of the precision circuit without daily manual blowing-down.
Start with the port step: 600 size carries a 3/4 in PT port, one step up from 1/2 in (size 400) and below 1 in. Match the size to the air demand of the line rather than the pipe alone. For regulation, this unit is the low-pressure (L) type - choose it where the process runs at gentle setpoints; the standard type suits general-duty work. The 40 um element is the default; specify the W code if finer 5 um filtration is needed. Drain options are differential-pressure (this unit, self-acting), automatic, or manual. Gauge choices are the embedded square type or an external round gauge in MPa, psi or bar scales - this unit carries the round psi gauge - and the K code adds a reverse/check valve. Threads come as PT (standard), G or NPT to order, and a bracket is included.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated figure, and the exact adjustment range of the low-pressure type is not stated as a single number either. Send us your line pressure, setpoint and air demand and we will confirm the sizing and figures against the datasheet before you commit.
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 the GFR family as performance curves rather than a single rated figure, so we do not quote a l/min or SCFM number on the page. Send us your line pressure, setpoint and air demand, and we will confirm the flow and the low-pressure adjustment range against the datasheet for your application before you order.
The L code means this regulator is built for circuits that run at gentle setpoints, where a standard regulator would sit at the very bottom of its turn and give coarse control. If your process needs ordinary general-duty regulation instead, order the standard type. The exact adjustment range of the low-pressure type is not published as a single figure, so we confirm it on request along with the datasheet.
