The AirTAC GFR200-08 AirTAC Filter Regulator G1/4 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 regulates downstream pressure in a single body. This 200-size unit carries a G1/4 (BSPP) port, a manual drain bowl in polycarbonate, a 40 um standard filter element, an embedded square gauge reading in psi, and a built-in reverse/check valve that holds downstream pressure when the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). With the manual drain fitted, the regulation range is 0.05-0.9 MPa (7-130 psi).
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 inch, and with choices of drain type, filter grade (40 um standard, 5 um with code W), gauge scale, thread (PT standard; G and NPT as catalogue options) and bracket. Flow is published as curves rather than a single rating, 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.

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.

Feeds a small bench-mounted pneumatic press or clamp fixture, giving the operator a filtered supply, a set working pressure on the psi gauge, and check-valve hold so the press does not creep if plant air drops.
Conditions the air feeding a cartoning or bagging machine's cylinder bank: water and grit are stripped before the valves, pressure is set per recipe, and the manual drain is bled at shift start.
Mounted at a workshop wall drop serving impact wrenches, ratchets and blow guns, keeping rust and scale out of the tools while the regulator sets a safe, repeatable working pressure.
Size and port are the first choice: the 200 size with its 1/4 in port suits lighter branch lines, while 300, 400 and 600 step up in port and flow capacity. Drain type matters in practice - manual drain (this unit, code M) needs an operator to bleed the bowl, whereas automatic or differential-pressure drains discharge condensate continuously; choose manual where the bowl can be checked as part of a routine. The 40 um element is the standard grade; specify W for the 5 um element if finer filtration is needed. The embedded square gauge here reads in psi (MPa and bar scales are also available), and the fitted K code adds a reverse/check valve. Thread is G (BSPP) on this unit; PT is the catalogue standard with G and NPT as options, and a bracket is included. Flow is published as curves, not a single rating, so 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 line pressure, set pressure and the air demand of your equipment, and we will confirm the flow figures from the datasheet for this exact model on request.
The M in the code means the polycarbonate bowl has a manual drain: condensate collects in the bowl and an operator bleeds it off, which suits points that are checked routinely. The K code adds a reverse/check valve, which holds the downstream pressure if the upstream supply is interrupted. With the manual drain, the regulation range is 0.05-0.9 MPa (7-130 psi).
