The AirTAC GFR200-08 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 AirTAC GFR200-08 is a filter regulator: it removes water and particulate from compressed air through a 40 um element and regulates downstream pressure in a single body. This configuration has a 1/4 in NPT port, a manual drain on the polycarbonate bowl, an embedded square gauge scaled in MPa, and a built-in check valve to hold the downstream setting when the supply is interrupted. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulating range is 0.05-0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, PT, G or NPT threads, and gauge options. Flow is published as curves rather than a single rating, so ask us to confirm the 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.
| 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. |
| 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. |
| 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.

Feeding clean, regulated air to the pneumatic cylinders on a carton-forming and sealing machine, with the check valve holding the set pressure through brief supply interruptions.
Supplying regulated air to the diverter gates and stoppers on a parcel-sorting conveyor, where the 40 um element keeps debris out of the directional valves.
Providing filtered, regulated air to pipetting and plate-handling instruments in a laboratory automation cell, with the manual drain for scheduled bowl emptying.
Size the unit by port and expected flow: size 200 with a 1/4 in NPT port suits compact circuits, and the larger sizes (300/400/600) step up in port and flow capacity - we can confirm curve data before you order. Choose the drain: manual (this unit, which also gives the widest regulating range of 0.05-0.9 MPa), automatic, or the differential-pressure default. Filter grade is 40 um standard; order the W suffix for 5 um. Gauge scale can be MPa, psi or bar, and the thread can be PT (standard), G or NPT. A mounting bracket is optional; this configuration is supplied without one. 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. 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 figure, so we do not quote a number here. Tell us your application and we will confirm the flow data from the datasheet before you order.
The M in the code sets a manual drain: the bowl is emptied by hand on a scheduled basis. It also gives the widest regulating range of 0.05-0.9 MPa (7-130 psi). Choose the A suffix for an automatic drain, or leave the position blank for the differential-pressure drain if the unit sits where manual draining is inconvenient.
