The AirTAC AirTAC GFR200-08 Filter Regulator 1/4 in, Manual Drain, psi 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 regulates downstream pressure in one body. This 200-size unit has a G1/4 (BSPP) port, a 40 um standard filter element, and a manual drain you open by hand to expel collected condensate. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the fitted round gauge reads in psi. A reverse/check valve is fitted, and the polycarbonate bowl is rated for a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing). No mounting bracket is included in this configuration.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will 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.

|---|---|
| 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. |

| 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. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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 the directional control valves on a carton-sealing or wrapping line, where clean, dry, correctly regulated air keeps valve spools shifting reliably shift after shift.
Supplying a bench-mounted pneumatic clamp or small press, where the operator sets a fixed working pressure on the psi gauge and the filter element keeps scale and water out of the cylinder.
Conditioning the air feeding gripper and slide actuators on an assembly cell, with the check valve helping hold the set circuit condition and the manual drain cleared during scheduled checks.
Start with the port: this unit is 1/4 in (G thread). If your line needs more flow, step up to GFR300, GFR400 or GFR600 - larger sizes carry larger ports, though the exact flow figure is published as a curve, not a single rating, so let us confirm sizing against your air demand before you order. On drain, manual suits points you visit routinely; choose automatic or differential-pressure drain where the unit is hard to reach. The standard element is 40 um; specify code W for 5 um if downstream equipment needs finer filtration. Gauge scale is selectable (MPa, psi or bar) and this configuration carries the external round gauge in psi. Thread is G (BSPP) here; PT is the catalogue standard and NPT is orderable. Brackets are optional - this unit omits one.
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 GFR flow as curves across the size range rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet before you order.
Manual drain (code M) means you open the drain by hand to expel collected water and dirt, which suits units fitted where operators already walk past. If the GFR200-08 will sit in an enclosed or hard-to-reach spot, choose the automatic or differential-pressure drain variant instead so condensate is handled without a visit.
