The AirTAC GFR200-08 AirTAC Filter Regulator PT1/4, 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 and holds downstream pressure steady in one body. This size 200 unit has a PT1/4 (1/4 in) port with PT thread, a manual-drain polycarbonate bowl, a 40 um filter element, a round psi gauge fitted, and a reverse/check valve. 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 spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of drain (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scale in MPa, psi or bar, and G or NPT thread options. 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.
| 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT 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.

Point-of-use conditioning ahead of the solenoid valves and clamping cylinders on a machining centre: the 40 um element strips water and swarf carryover while the regulator holds a steady setting for repeatable clamping.
Feeding sealing jaws, baggers and vacuum generators on a packaging line, where the manual-drain bowl is emptied at shift checks and the check valve keeps downstream pressure from backing up when upstream supply dips.
Supplying diverters, stoppers and gate cylinders on a distribution conveyor, with the round psi gauge giving operators a visible setpoint at the drop and the filter keeping moisture out of the gate valves.
Pick the size by the port step: this 200 unit carries PT1/4, while 300, 400 and 600 step up to larger ports and higher flow. Drain is a real choice - manual (this unit, which also widens the regulating range to 0.05-0.9 MPa), automatic, or the differential-pressure default. Filter grade is 40 um standard or 5 um with code W. Gauges are an embedded square gauge or an external round gauge, with MPa, psi or bar scale. Thread is PT as standard; G (BSPP) and NPT are order options, and a mounting bracket is optional. Flow is published as curves, not a single rating, so let us confirm sizing against your application before you order.
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.
Flow for the GFR200-08 is published 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 datasheet flow curve and sizing on request before you order.
This GFR200-08 has a manual drain: the bowl is emptied by opening the drain at regular intervals. If the unit sits where it cannot be serviced often, the same family is available with an automatic drain (code A) or the differential-pressure default. Manual drain also gives the wider 0.05-0.9 MPa (7-130 psi) regulating range.
