The AirTAC GFR200-08 AirTAC Filter Regulator PT1/4, 5 um, Manual Drain 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: water and particulate filtration plus downstream pressure regulation combined in one compact body. This configuration is built for a 1/4 in PT port, carries the fine 5 um filter element (code W) instead of the 40 um standard element, and uses a manual drain, so an operator opens the drain at the bottom of the polycarbonate bowl to expel collected condensate. It is the low-pressure type (code L) for circuits set below standard regulator ranges, and it ships as coded with an external round pressure gauge reading in psi and a built-in reverse (check) valve, with no mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of manual, automatic or differential-pressure drain, 40 um or 5 um filtration, gauge style and scale, 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 rated figure, so ask us and we will confirm the datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 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.

Feeding paint spray guns on a woodworking line: the 5 um element catches fine particulate before the gun, the regulator holds a steady low set pressure for finish consistency, and the manual drain is emptied during shift-end cleanup.
Supplying carton-taping and sealing heads on a packaging conveyor: filtered, regulated air keeps actuator strokes repeatable, the check valve holds the downstream circuit if supply dips, and the psi gauge lets line staff verify settings at a glance.
Bench setups where instruments and small cylinders need clean, finely regulated air: the 5 um grade protects sensitive components, the low-pressure type suits reduced set pressures, and the compact size-200 body fits tight bench space with no bracket needed.
Start with the port step: this unit is size 200 with a 1/4 in PT port, so size up to GFR300/400/600 if your line needs larger ports and more flow. Choose the drain to match maintenance: manual (as coded here) is emptied by hand, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Pick the 5 um element (this unit) when downstream equipment needs finer filtration than the 40 um standard. The low-pressure type (L) suits circuits regulated below standard ranges; the exact range for this variant is not published, so confirm with us. Gauge style is embedded square as standard with an external round gauge optional, in MPa, psi or bar scales - this unit carries the round psi gauge. Thread is PT as standard; G (BSPP) and NPT are order options. A bracket is optional (this unit has none, code J), and the K code adds the reverse/check valve fitted here.
One honest note before ordering: flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you commit.
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 rated flow, Cv or SCFM figure. Send us your application - port size, expected consumption and line pressure - and we will confirm the datasheet flow curve and check the sizing for you before you order.
This configuration is coded M for a manual drain: an operator opens the drain under the polycarbonate bowl to release collected condensate, which suits installations that are checked regularly. If the unit will run unattended or in humid conditions, the automatic drain (code A) expels water continuously without attention, and the differential-pressure drain (the default) drains on a pressure drop. All three are catalogue options across the GFR family.
