The AirTAC GFR20008MC2WT AirTAC Filter Regulator, NPT 1/4 in, 5 um 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.
This GFR200-series unit combines water and particulate filtration with downstream pressure regulation in a single body, so one component both cleans the air and holds a set working pressure. This configuration is the 200 size with a 1/4 in NPT port, fitted with a fine 5 um filter element (code W) for cleaner air than the standard 40 um grade, a manual drain you operate by hand to clear collected condensate, and a round pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7 to 130 psi), the polycarbonate bowl suits non-freezing compressed air from -5 to 70 C, and a mounting bracket is included.
This is a genuine AirTAC part supplied by airtacdistr.com for the US market. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

Placed ahead of directional valves and small cylinders on a machine's air supply, this unit filters condensate and fine particles at 5 um and holds a steady regulated pressure so valve shifting and cylinder seating stay consistent through the shift.
On a workholding clamp or light pneumatic press fed from a shop compressor, the regulator lets the setter dial in clamping pressure from 0.05 to 0.9 MPa while the 5 um element keeps sludge and pipe scale out of the clamping cylinder.
For test benches and lab apparatus that need clean, repeatable air at a fixed pressure, the fine 5 um grade plus a round psi gauge gives the operator a readable, stable setpoint, with the manual drain emptied as part of the rig's start-up routine.
Start with the port step: the GFR range runs 200/300/400/600 sizes across 1/8 to 1 inch ports, and the right size is the one whose flow curve covers your demand with margin - we can check that against the datasheet on request. This unit is already set for the fine 5 um element; the standard grade is 40 um, so choose 5 um where downstream valves, cylinders or instruments need cleaner air. The manual drain here suits installations where an operator can bleed the bowl routinely; pick automatic or differential-pressure drain types where the unit is hard to reach. Gauge choices are the embedded square type or an external round gauge, in MPa, psi or bar scales - this one is round, psi. Threads are PT as standard with G and NPT as orderable options; brackets are included unless the J code says otherwise. Because flow is published as curves and not a single rating, ask us to 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR range as curves, not as a single rated number, so we do not quote a flow figure on the product page. Tell us your line pressure, working pressure and air demand and we will confirm the correct size from the datasheet curves on request before you order.
The M in the code means the bowl drain is operated by hand: an operator opens it periodically to release collected condensate, which suits accessible mounting points with a supervised routine. The W code sets the filter element to 5 um instead of the standard 40 um, removing finer particles for downstream valves, cylinders and instruments. The round gauge fitted here reads in psi; square gauges and MPa or bar scales are available in the range.
