The AirTAC Airtac GFR Filter Regulators GFR20008MJF3WT 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 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single compact body. This size 200 unit carries a 1/4 in NPT port, a 5 um filter element for finer air quality than the standard 40 um grade, and a manual drain you operate by hand to empty the polycarbonate bowl. The fitted square gauge reads outlet pressure in bar, and the standard regulator adjusts across its specified range. No mounting bracket is included with this configuration.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is offered with a choice of drain type, filter grade, gauge style and scale, thread form and bracket. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow figures for your application 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 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. |
| 3 | Gauge scale: bar. 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.

Feeding clean, regulated air to a bench-mounted pneumatic press on an assembly line, where the 5 um element protects the press valve and the regulator sets consistent working pressure for repeatable forming strokes.
Conditioning the shop-air feed to a CNC machining centre's pneumatic clamps and tool-change actuators, with the manual-drain bowl emptied as part of daily machine checks and the bar gauge giving the operator a direct pressure readout.
Supplying filtered, regulated air to the diverters, sealers and pusher cylinders on a packaging conveyor, where the single filter-regulator body saves panel space and the 5 um grade keeps the line's directional valves clean.
Size and port: the GFR family steps through sizes 200, 300, 400 and 600, with larger sizes taking larger ports and more flow - match the size step to your line's air demand rather than fitting the port to the pipe alone. Drain: this unit is manual-drain, which suits attended installations; automatic or differential-pressure drains are available if the bowl cannot be drained by hand. Filter grade: 5 um (this unit, code W) versus the standard 40 um - choose 5 um where downstream valves and instruments need cleaner air. Gauge: the embedded square gauge is standard here reading in bar; an external round gauge with MPa, psi or bar scales is optional. Thread: PT is the standard thread, with G (BSPP) and NPT (this unit) as order options; bracket is an option this configuration omits. Flow is published as curves, not a single rating, so 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 G-series flow as performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or l/min number for this unit. Tell us your application and line conditions and we will confirm the flow and datasheet figures for the GFR200-08 on request before you order.
The M in the code GFR20008MJF3WT specifies a manual drain: the polycarbonate bowl is emptied by hand, which suits installations that are checked regularly. The GFR family also offers an automatic drain (code A) and a differential-pressure drain (the default, no code letter) if the bowl cannot be drained manually - just ask for the variant you need.
