The AirTAC AirTAC GFR600C20MLC1WTK Filter Regulator NPT3/4 5 um 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 AirTAC GFR600C20MLC1WTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built for a 3/4 in NPT port, carries the fine 5 um filter element (code W), and uses a manual drain, so an operator opens the drain at the bowl to discharge collected condensate. It is the low-pressure regulator type, is fitted with an external round pressure gauge scaled in MPa, includes a reverse (check) valve (code K), and comes with a mounting bracket. The size 600 bowl is aluminium alloy, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, gauge and scale options, G (BSPP), NPT or PT threads, and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the flow and datasheet figures 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. 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.

A bag-sealing or tray-sealing station on a packaging line often runs at a reduced pressure set well below the main header. This GFR600 low-pressure filter regulator cleans the air of water and fine particles and holds the reduced setting, with the MPa gauge giving the operator a clear reading at the machine.
On a plant air main sized at 3/4 in NPT, directional and process control valves last longer when supplied with dry, filtered air at a stable pressure. This unit filters to 5 um and regulates in one body, and the fitted check valve holds the setting in the line it feeds.
A workholding clamp or light pneumatic press needs consistent, filtered air at a controlled pressure to repeat its cycle reliably. Mounted on its included bracket close to the machine, this size 600 unit conditions the supply, and the manual drain lets maintenance empty collected condensate during scheduled checks.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start there when your line's consumption sits near the top of what smaller 1/4 in to 1/2 in units can pass; the honest check is to match the published flow curve, not a single number, so let us confirm sizing against your demand before you order. This unit pairs that port with the 5 um element (code W) instead of the 40 um standard, which suits downstream components that need finer particulate removal; the trade-off is a finer element to monitor. The manual drain means someone opens the bowl drain to remove condensate, which is simple and reliable where a technician visits the unit regularly; automatic or differential-pressure drains are available on other GFR codes if unattended draining matters. The low-pressure regulator type is chosen where the controlled pressure sits well below full line pressure, and we will confirm the exact set range from the datasheet on request. The round MPa gauge is fitted as ordered; square embedded gauges and psi or bar scales are alternatives. Thread here is NPT, with G (BSPP) and PT available as order options, and the mounting bracket is included.
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 series as curves, not as a single rated figure, so we do not quote a flow number for this unit. Send us your line pressure and your air demand, and we will confirm the flow from the datasheet and check that the size 600, 3/4 in port suits your application before you order.
The M in the code specifies a manual drain: condensate collected in the aluminium alloy bowl is released by opening the drain by hand, which suits stations visited during routine maintenance. If the unit will sit unattended, other GFR600 codes offer an automatic drain or the differential-pressure drain, and we can quote the equivalent configuration on request.
