The AirTAC Airtac GFR Filter Regulators GFR20008MJF1WT 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 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 AirTAC GFR200-08 is a size-200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This configuration has a 1/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain bowl in PC (polycarbonate), a standard regulator with a 0.05-0.9 MPa (7-130 psi) adjustment range, and an embedded square gauge scaled in MPa. No reverse/check valve is fitted and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drain, 40 um or 5 um filtration, gauge scale options and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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). |
| F | Gauge shape: Square. 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.

Point-of-use conditioning on a machining centre: the 5 um element strips water and fine particulate before air reaches tool-changer and clamping circuits, while the regulator holds a steady set pressure for consistent actuator performance.
Feeding pick-and-place and sealing cylinders on a packaging conveyor: clean, regulated air keeps stroke timing repeatable through a shift, and the manual drain is emptied during scheduled line cleaning.
Conditioning atomising air at a spray booth: the 5 um grade helps keep moisture and particles out of the air line ahead of the gun, and the MPa gauge lets the operator verify the regulator setting at a glance.
Start with the port step: this unit is 1/4 in NPT in size 200, the smallest GFR frame - step up to GFR300/400/600 if your line needs larger ports and higher flow capacity. The 5 um element here suits air that feeds sensitive components; choose 40 um where coarser protection is enough. The manual drain means an operator opens the bowl drain periodically - pick automatic or differential-pressure drain if you cannot schedule that. The square gauge reads in MPa; psi and bar scales are catalogue options, as is an external round gauge. PT is the standard thread; G and NPT are order options, and this unit is specified with NPT. No bracket is included with this code.
Because flow is published as curves rather than a single rated figure, we do not quote a number here - send us your application details and we will confirm sizing against the datasheet before you order.
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 this family as curves, not as a single rated number, so we do not state a figure here. Tell us your working pressure and the air demand of your equipment and we will confirm the flow from the datasheet on request before you order.
This unit is coded M for a manual drain: collected condensate stays in the PC bowl until an operator opens the drain fitting. That suits attended installations with regular maintenance rounds. If the unit will sit unattended, ask about the automatic or differential-pressure drain variants of the same GFR200 size.
