The AirTAC GFR60020MLC1WT AirTAC Filter Regulator 3/4 NPT 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MLC1WT is a size 600 filter regulator: it removes water and particulate from compressed air and sets a reduced working pressure downstream, in one body. This configuration is built for a 3/4 in NPT port, carries the 5 um filter element (code W) for finer filtration than the standard 40 um grade, and uses a manual drain, so the bowl is emptied by opening its drain valve during routine checks. It is the low-pressure type, suited to circuits that run at reduced setting points, and the exact setting range is not published - we confirm it on request. The bowl on size 600 units is aluminium alloy, a round external gauge scaled in MPa is fitted, and the mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drain, 40 um standard or 5 um filtration, standard or low-pressure regulation, gauge type and scale options, PT, G or NPT threads, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Filtered and pressure-reduced air for spray guns in a finishing booth: the 5 um element helps keep water and particles out of the air path, while the low-pressure regulator holds the reduced setting the gun circuit is set up for.
Supply point for the pneumatic cylinders and actuators on a packaging conveyor, where the filter-regulator cleans the shop air and holds a stable reduced pressure so the forming and sealing motions repeat consistently.
Instrument-air feed for lab automation benches and test rigs, where the 5 um grade protects sensitive pneumatic components and the low-pressure type matches circuits that run at reduced supply settings.
Step through the decodable choices in order. First, size and port: 600 is the largest G-series size and this unit takes a 3/4 in NPT port, so match it to your line size and expected air demand - we confirm flow against the published curves rather than quoting a single rated figure. Second, drain type: this unit is manual drain, which suits attended installations; automatic and differential-pressure drain variants exist if you prefer the bowl to clear itself. Third, filter grade: 5 um (this unit) versus the 40 um standard - choose 5 um where downstream equipment needs finer protection. Fourth, gauge: this unit carries the external round gauge scaled in MPa; square embedded gauges and psi or bar scales are alternatives. Thread is NPT here, with PT (standard) and G also available to order, and the bracket is included.
Because flow data is published as curves and not as a single rating, ask us to confirm sizing against your application before you order. The low-pressure regulator setting range for this type is likewise confirmed on request.
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 number here. Tell us your line size, working pressure and air demand, and we will confirm the flow from the datasheet curves for this 3/4 in NPT, size 600 unit before you order.
This unit has a manual drain: the bowl is emptied by opening its drain valve during routine checks, which suits installations that are visited regularly. The GFR family also offers automatic drain (code A) and differential-pressure drain (the default) if you want the bowl to clear without operator action.
