The AirTAC AirTAC GFR600-20T 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 GFR600 combines water and particulate filtration with pressure regulation in a single body. This 600-size unit is threaded 3/4 in NPT, carries a 5 um filter element for finer air cleaning than the standard 40 um grade, and releases collected condensate by hand through its manual drain. The aluminium alloy bowl suits this largest frame, and the fitted round gauge reads in psi so downstream pressure can be set and monitored at a glance. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05-0.9 MPa (7-130 psi), and the unit operates from -5 to 70 C in non-freezing conditions.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options including automatic, manual or differential-pressure drains, 40 um or 5 um elements, gauge style and scale, PT, G or NPT threads, and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm 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 0.05 - 0.9 MPa (7 - 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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.

Installed at the air drop feeding a paint booth, it removes water and fine particles that would spoil finish quality and holds the spray supply at the pressure the booth was set up for. The 5 um element and psi gauge support that job directly.
Feeds the clamping cylinders on a machining centre: the regulator holds a steady clamp pressure, the 5 um element keeps condensate and fine dirt out of the valve stack, and the gauge lets a setter verify the setting at the machine.
Sits at the take-off feeding diverters and pusher cylinders on a packaging conveyor, cleaning the shop air and holding the pressure the line was commissioned at. The manual drain is emptied as part of routine shift checks.
Choose the 600 size with its 3/4 in port when your line volume calls for the largest GFR frame; the 200, 300 and 400 sizes step down in port and capacity. A manual drain means an operator opens it periodically to release condensate - automatic or differential-pressure drains are the alternatives where that cannot be scheduled. The 5 um (W) element suits air feeding sensitive components; the standard grade is 40 um. This unit carries a round gauge on the psi scale; an embedded square gauge and MPa or bar scales are the other options. Thread here is NPT, with PT as the standard and G (BSPP) available to order, and no mounting bracket is fitted. Because flow is published as curves rather than one rated figure, 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. 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 rather than a single rated figure, so no flow number is quoted here. Tell us your application and we will confirm the flow from the datasheet before you order.
The M in the code specifies a manual drain: an operator opens it to release collected condensate, which suits lines with regular checks; automatic and differential-pressure drains are available if you cannot schedule that. The W specifies the 5 um element, one grade finer than the 40 um standard, for air feeding sensitive components.
