The AirTAC GFR600C20MLJNWT AirTAC 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 GFR600C20MLJNWT is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in a single body, sized 600 with a 3/4 in NPT port. This configuration is the low-pressure type (code L) with a 5 um filter element (code W) for finer water and particulate removal, a manual drain (code M) that you open by hand to empty collected condensate, and a metal bowl - at size 600 the bowl is aluminium alloy. No gauge is fitted (code N) and no mounting bracket is included (code J).
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, and options across drain type, filter grade, gauge, thread (PT standard, G and NPT to order) and bracket. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow figures for your application on request.

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 carton-sealing or case-packing machine that runs clamp and hold-down cylinders at reduced pressure, this filter regulator cleans the supply to 5 um and holds the low working pressure the cylinders were set up for, with the 3/4 in port feeding the machine's main drop.
Feeding spray guns or air-assisted applicators where finer filtration matters, the 5 um element strips water and particulate from the shop air line and the low-pressure regulator sets the gentler atomising pressure, while the manual drain lets maintenance empty the aluminium bowl at shift end.
On a test rig or process skid where instruments and pneumatic actuators need clean, low-pressure air rather than full header pressure, this unit filters to 5 um and steps the supply down, with NPT3/4 plumbing matching the skid's inlet.
Start with the port step: size 600 with a 3/4 in NPT port is the largest GFR size, so match it against the air demand of the line it feeds - if your demand sits below what a 3/4 in line carries, a smaller GFR size may suit. Drain type is a real choice here: manual (this unit) means an operator drains the bowl, while automatic and differential-pressure drains discharge condensate without attention; choose manual where draining can be scheduled. The 5 um element (code W) is the finer option versus the 40 um standard - pick 5 um where downstream equipment needs cleaner air. Gauge and scale are selectable on GFR units generally, but this code carries none; add a gauge code if you need local pressure indication. Thread is NPT here (PT is the standard; G and NPT are order options), and code J means no bracket is supplied.
One honest note before ordering: AirTAC publishes flow as curves, not a single rated figure, and the exact regulation range of the low-pressure type is not stated here - so ask us to confirm sizing and the low-pressure range against your application 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 the GFR600 as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and air demand and we will confirm the flow figures from the datasheet on request before you order.
Manual drain (code M) means condensate collected in the aluminium bowl is emptied by opening the drain by hand - simple and reliable where draining can be scheduled, versus automatic or differential-pressure drains that discharge on their own. The 5 um element (code W) is the finer filter grade compared with the 40 um standard, giving cleaner air for sensitive downstream equipment.
