AirTAC GFR600-20 Filter Regulator (GFR60020MC1GK)
The AirTAC AirTAC GFR600-20 Filter Regulator (GFR60020MC1GK) 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 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.

About the AirTAC GFR600-20 Filter Regulator (GFR60020MC1GK)
The AirTAC GFR600 is a G-series filter regulator: filtration and pressure regulation combined in a single body, for compressed air only. This configuration is the 600 size (the largest in the series) with a G3/4 BSPP port, a manual drain bowl, the standard 40 um filter element, an external round pressure gauge scaled in MPa, and a reverse (check) valve fitted so downstream pressure is held when the upstream supply is removed. In use it cleans water and particulate from the air line and holds a set downstream pressure in one compact unit.
This is a genuine AirTAC part. The G-series spans 200, 300, 400 and 600 sizes, with PT, G (BSPP) and NPT thread options, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filter elements, gauge choices and bracket options. Maximum working pressure is 1.0 MPa (145 psi); with a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi); the 600 size bowl is aluminium alloy. Flow figures are published as curves rather than a single rating, so we confirm datasheet and sizing figures 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 0.05 - 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. |
| (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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Where the AirTAC GFR600-20 Filter Regulator (GFR60020MC1GK) Is Used
Bottling line air supply
Mounted on the main air drop feeding a bottling hall's filler and capper actuators, it cleans incoming plant air and holds a steady regulated pressure for the machine's pneumatic valves, while the check valve keeps the downstream circuit pressurised during supply dips.
Actuated valve control at a water treatment plant
Installed ahead of solenoid-piloted actuators on an actuated valve manifold, it removes water carryover from the plant air ring main and provides the regulated pilot pressure the positioners need, with the manual drain serviced during scheduled rounds.
Conveyor pneumatics in an automotive body shop
Fitted at the feed to stopper-lift and sensor-arm cylinders along a body-in-white conveyor, it conditions the shop air supply and maintains the set working pressure the cylinder circuits were sized around, holding it via the fitted check valve.
Is the AirTAC GFR600-20 Filter Regulator (GFR60020MC1GK) the Right Unit?
The 600 size with a 3/4 in port suits larger air supply lines where higher flow demand and bigger pipework are expected; step down to 400, 300 or 200 with 1/2 in to 1/8 in ports for smaller lines. The manual drain here means someone bleeds the bowl, and the 40 um element is the standard grade for general plant air - choose the W option (5 um) only where finer filtration is genuinely needed. The MPa round gauge is specified in the code; the embedded square gauge with psi, bar or MPa scales is an alternative, and the K code adds a reverse/check valve. Thread is G (BSPP) as ordered; PT is the standard option and NPT is also available. Bracket inclusion is a decodable choice too. Because flow is published as curves, not a single rated figure, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/4" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.05 - 0.9 MPa (7 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC GFR600-20 Filter Regulator (GFR60020MC1GK) FAQ
AirTAC publishes flow for the G-series as curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote. Tell us your line pressure and demand and we will confirm the flow and sizing data from the datasheet on request.
The M code specifies a manual drain: an operator opens the drain to bleed accumulated water from the aluminium alloy bowl, typically during scheduled checks. It suits installations where a float or differential-pressure drain is not wanted; automatic and differential-pressure drain versions of this unit are also available to order.
