The AirTAC GFR20008MC2 AirTAC Filter Regulator 1/4in PT, 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 GFR20008MC2 is an AirTAC GFR200 filter regulator: filtration and pressure regulation combined in a single body, sized for a PT1/4 (1/4 in) port. It removes water and particulate from compressed air at the standard 40 um grade, then regulates downstream pressure across a 0.05-0.9 MPa (7-130 psi) adjustment range. This configuration carries a manual drain, so the bowl is emptied by hand as part of routine maintenance, and it is supplied with a mounting bracket. The bowl on this 200 size is polycarbonate (PC), and the unit includes a round external gauge reading in psi; the embedded square gauge is the standard fitting, with MPa/psi/bar scales available.
This is a genuine AirTAC part. The GFR series is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, an optional 5 um filter grade (code W), G or NPT thread options, and gauge or no-gauge variants. Flow figures for the series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

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.

Mounted at the inlet of a workstation's air drop, the GFR20008MC2 cleans the supply at 40 um and lets the operator set a stable working pressure for cylinders and air tools, with the psi gauge giving a direct local readout.
On carton sealers and labelling heads fed at 1/4 in, this filter regulator protects directional valves and actuators from water and debris while holding the pressure the machine's cycle was set up for.
Where a control panel or sensor cluster needs clean, regulated air at a fixed setting, the compact 200 body, included bracket and round psi gauge make it straightforward to mount inside or beside the cabinet and set once.
Choose the GFR size by the port and flow your line needs: this 200 size with PT1/4 suits compact circuits and branch supplies, while 300/400/600 steps up port and capacity. Pick the drain to match duty: manual drain (this unit) suits attended installations where an operator can bleed the bowl; automatic or differential-pressure drains suit unattended runs. The standard element is 40 um; specify the W option for 5 um where finer filtration matters. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included for panel or wall mounting. Flow for the series is published as curves, not a single rated figure, 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR-series flow as performance curves rather than a single rated figure, so we do not quote a l/min or SCFM number on the page. Tell us your inlet pressure and the flow your circuit needs, and we will confirm the datasheet curve and correct sizing for the GFR200 before you order.
This unit's manual drain means the polycarbonate bowl is emptied by hand during maintenance, which suits attended machines and panels checked on a routine schedule. If the installation runs unattended or in humid conditions where condensate collects quickly, choose the automatic (code A) or differential-pressure (blank) drain variant instead; the adjustment range and filtration are otherwise the same.
