The AirTAC GFR20008MJC1T AirTAC Filter Regulator NPT1/4 - Manual Drain 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 PT1/4" 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 GFR20008MJC1T is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure over 0.05-0.9 MPa (7-130 psi). This configuration is sized for 1/4 in NPT ports, carries a manual drain bowl in PC (polycarbonate), and is fitted with an external round gauge scaled in MPa. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with a choice of port sizes, G/NPT thread options, manual, automatic or differential-pressure drains, a 5 um (W) filter element option, gauge style and scale, and bracket options. Flow figures for the GFR series are published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| 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. |
| 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. |
| 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.

Feeds clean, regulated air to directional control valves on a carton-sealing or wrapping machine, with the manual drain bled during shift-start checks to keep condensate out of the valve stack.
Mounted at the drop from a workshop air main to a bench, it filters line dirt and water and lets the operator set a stable working pressure for air tools and small cylinders.
Provides filtered, manually adjustable air to a test bench or pilot rig where the 40 um element protects sensitive instruments and the MPa round gauge gives a clear set-point reading.
Start with the port size: this unit is the 200 size with 1/4 in NPT threads, so match it to the line size and the flow your circuit needs - larger GFR sizes (300/400/600) carry larger ports and more flow. Next choose the drain: this version has a manual drain, which suits positions where an operator can bleed the bowl on a routine; automatic or differential-pressure drains suit unattended installations. The 40 um element is standard; specify the W code if your application needs 5 um filtration. The round gauge here reads in MPa; psi and bar scales are available. Thread is NPT as coded, with PT and G (BSPP) available as order options, and brackets can be added if the unit is not panel- or body-mounted. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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. Tell us your line size and required flow and we will confirm the datasheet curve and correct sizing on request before you order.
The M in the code specifies a manual drain bowl, which an operator empties periodically. If the unit will sit unattended, the same GFR200 body is available with an automatic (A) or differential-pressure (blank) drain - note that the regulation range differs by drain type, so confirm the variant you need when ordering.
