The AirTAC GFR20008MC3TK AirTAC Filter Regulator NPT1/4 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 GFR20008MC3TK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This 200-size unit has a 1/4 in NPT port, a 40 um standard filter element, a manual drain bowl in polycarbonate, a fitted reverse/check valve, an included mounting bracket, and an external round gauge reading in bar. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with manual drain, and the maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GFR range is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, and a 5 um element option. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and 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. 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.

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Clean, regulated air feeding a bench-top pneumatic press or clamping fixture, where the operator checks and drains the bowl as part of a routine and the bar gauge gives a quick setpoint check.
Point-of-use air preparation for a cartoning or wrapping machine, filtering water and debris out of the supply before it reaches directional valves and cylinders on the packaging line.
Regulated air for conveyor-mounted stoppers, pushers and diverters, with the check valve holding the set pressure against momentary upstream dips and the manual drain emptied during shift checks.
Start with the size and port: 200 is the smallest GFR frame, and the 1/4 in NPT port here must match your supply line and the flow your application needs - step up to 300, 400 or 600 if the line is larger. This unit carries the 40 um standard element; choose the W-coded 5 um option if downstream valves or cylinders need finer filtration. The manual drain (M code) means an operator drains the bowl, which suits periodically attended installations; automatic or differential-pressure drains suit unattended lines. The C3 gauge code gives an external round gauge reading in bar; embedded square gauges with MPa, psi or bar scales are also available. Thread is NPT here, with PT (standard) and G as order options, and the bracket is included.
Because flow is published as curves rather than a single rating, 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 number, so we do not quote a rated flow figure. Tell us your line pressure and the air demand of your equipment and we will confirm the correct size from the datasheet curves on request before you order.
The M code in GFR20008MC3TK selects a manual drain: the polycarbonate bowl is emptied by hand, which suits attended installations on a maintenance schedule. The C3 code fits an external round gauge reading in bar; if you prefer an embedded square gauge or an MPa or psi scale, those are available in the same series.
