The AirTAC GFR20008MJF2WK AirTAC Filter Regulator PT1/4, 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 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 GFR20008MJF2WK is an AirTAC GFR200 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration is sized for a PT1/4 (1/4 in) port, carries the fine 5 um filter element instead of the standard 40 um, and uses a manual drain, so an operator opens the bowl drain to remove collected condensate on a chosen schedule rather than relying on an automatic or differential-pressure drain. It is fitted with an embedded square gauge reading in psi, a reverse/check valve to hold downstream pressure, and is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family is available in sizes 200, 300, 400 and 600 with a choice of ports, thread types (PT standard, G and NPT as order options), drain types, filter grades and gauge scales. Flow is published by AirTAC as curves rather than a single rated figure, 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.

| 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. |

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.

Supplying clean, regulated air to the clamping and tool-change cylinders on a CNC machining centre, where the 5 um element protects close-tolerance valves from water and fine particles and the check valve holds the clamp circuit if upstream pressure dips.
Feeding the diverter and stopper cylinders along a packaging or bottling conveyor, with the square psi gauge letting line staff verify set pressure at a glance and the manual drain emptied during scheduled changeovers.
Conditioning shop-air supply for a laboratory or QA test bench that actuates fixtures and small pneumatic devices, where the 5 um grade and a stable, gauge-monitored setting keep the bench air clean and repeatable.
Choose the size and port against the air your circuit actually uses: the GFR200 with its PT1/4 port is the compact step in the range, and the larger 300/400/600 sizes carry bigger ports and more flow. This unit already fixes several choices for you: 5 um filtration (finer than the 40 um standard, for cleaner air at the point of use), a manual drain (simple and low-cost, but it needs someone to drain the bowl), a square psi gauge, and a reverse/check valve. If you would rather not depend on manual draining, an automatic-drain variant is available in the family. Thread is PT as standard, with G (BSPP) and NPT as order options; a mounting bracket can be added if you do not want the no-bracket version. Because AirTAC publishes flow only as curves and not as a single rated number, 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. The reflux valve permits reverse flow 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 number, so we do not quote a l/min or SCFM figure. Tell us your operating pressure and the air your circuit needs, and we will confirm the flow from the datasheet for this exact model before you order.
The M in the code GFR20008MJF2WK specifies a manual drain: condensate collected in the bowl is released by opening the drain by hand, typically as part of a maintenance routine. If you prefer not to rely on manual draining, GFR variants with automatic or differential-pressure drains are available in the same family - ask us for the matching model code.
