The AirTAC GFR200-08 AirTAC Filter Regulator, NPT1/4, 40 um 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: it removes water and particulate from compressed air and regulates downstream pressure in a single body, with a 1/4 in NPT port. This configuration carries a 40 um standard filter element, a manual drain on the bowl, a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi), an embedded square gauge scaled in psi, and a reverse (check) valve. The polycarbonate bowl includes a mounting bracket, 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 family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include automatic or differential-pressure drains, a 5 um element (code W), low-pressure regulation, gauge scale in MPa or bar, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so we confirm 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.

|---|---|
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 tape heads and flap tuckers on a carton sealing machine, with the check valve holding the set pressure if the supply dips mid-cycle.
Conditions and regulates the air feeding clamps and swing cylinders on a CNC cell, where a stable set pressure keeps parts clamped consistently through the cycle.
Supplies filtered, regulated air to gripper valves and vacuum ejector manifolds on a robotic pick-and-place station, with the psi gauge giving operators a visible setpoint.
Start with the size and port: the 200 frame with a 1/4 in NPT port suits lines fed at that connection size, and stepping up to sizes 300, 400 or 600 buys larger ports and more flow capacity. Choose the drain to match maintenance routines: this unit's manual drain needs someone to bleed the bowl, while automatic and differential-pressure drains (available in the family) discharge condensate without attention. Pick 40 um for general air prep or the 5 um W element where finer filtration matters, and choose the gauge scale - this unit is psi-scaled; MPa and bar are options. Thread is NPT here; G (BSPP) and the PT standard are the other catalogue choices, and brackets are included on this size. Because flow is published as curves rather than one rated number, 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 flow your equipment needs, and we will confirm against the datasheet curves whether the size-200, 1/4 in unit is correctly sized before you order.
The M in the code means the polycarbonate bowl has a manual drain: an operator bleeds accumulated condensate by hand. If the unit sits where nobody checks it regularly, the family's automatic (code A) or differential-pressure (blank) drain options discharge condensate without attention - both are available in the same size and port.
