The AirTAC GFR200-08 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 GFR200-08 is a size-200 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration has 1/4 in NPT ports, a 40 um standard filter element, a manual drain bowl in polycarbonate, and a round pressure gauge reading in bar. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and with options including automatic or differential-pressure drains, a 5 um (W) filter element, square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

| 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)). |

| 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. |
| T | NPT 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.

Feeds clean, regulated air to the tool-change and clamping circuits of a CNC machining centre, with the round bar gauge giving the operator a clear setpoint readout at the machine.
Conditions the air feeding cylinders and diverters on a carton packaging line, filtering water and debris before it reaches the valves and holding the actuator pressure steady through the shift.
Serves as the first-stage filter-regulator in a control panel or manifold cabinet, protecting downstream directional valves and logic elements from condensate and particles at a set pressure.
Start with the port and size step: this unit is size 200 with 1/4 in NPT ports; larger sizes (300/400/600) carry bigger ports and higher flow, so step up if your line demands more air. Choose the drain to suit access: manual drain (this model) needs someone to open it periodically, while automatic or differential-pressure drains suit unmanned installations. The 40 um element is standard; specify the W option for 5 um filtration where finer protection is needed. Gauges are available embedded square or external round, with MPa, psi or bar scales - this unit has a round gauge reading bar. Threads can be ordered in G (BSPP) or NPT instead of the PT standard, and a mounting bracket is included. Flow is published as curves, not a single rating, so please 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and datasheet figures for this unit on request before you order.
The M in the code specifies a manual drain: condensate collects in the polycarbonate bowl until someone opens the drain. It suits installations with regular operator attention; for unmanned or hard-to-reach points, the automatic (A) or differential-pressure (blank) drain options remove the need for manual draining.
