The AirTAC AirTAC GFR200-08 Filter Regulator G1/4, 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 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries a G1/4 (BSPP) port, a manual-drain polycarbonate bowl, a 40 um filter element, an embedded square gauge reading in psi, and a reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi). No mounting bracket is included on this version.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch and PT, G or NPT threads. Drain type, filter grade (40 um standard, 5 um optional with code W), gauge scale and bracket options can be selected to suit the installation. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

| 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. |
| G | G (BSPP) 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.

Mounted ahead of a valve manifold on a carton-sealing or filling line, this unit strips water and debris from the shop air and holds a steady set pressure so the solenoid valves shift consistently through every cycle. The manual drain is emptied during scheduled changeovers, and the check valve holds the downstream circuit if supply pressure dips.
Feeding a robot gripper and its control valves, this filter regulator gives the cell clean air at a fixed, repeatable pressure so part grip is consistent from the first cycle to the last. The square psi gauge lets a technician set and verify the gripping pressure at the cell, and the G1/4 port suits compact gripper manifolds.
Installed at the drop from a plant air ring main to a bench with air tools, cylinders or clamps, this unit conditions the air locally and lets each operator dial the working pressure for the job at hand. The 40 um element protects downstream tools from particulate, and the check valve keeps the bench circuit from back-feeding the main.
Step through the GFR sizes (200/300/400/600) to match the port and flow your line needs; this GFR200 unit carries a G1/4 port. Drain choice matters: the manual drain on this unit needs periodic bowl draining, while automatic and differential-pressure drains discharge condensate without attention. Filtration is 40 um standard; choose code W for 5 um where finer filtration is required. The embedded square gauge here reads psi, with MPa and bar scales and an external round gauge available as options. Thread is G (BSPP) on this model - PT is the standard thread and NPT is an order option, and a bracket can be added if the unit will be wall-mounted. Flow is published as curves, not a single rating, 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. 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 rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and the flow your application needs, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code GFR20008MJF2GK selects a manual drain: condensate collects in the polycarbonate bowl until you open the drain, typically during a scheduled check or changeover. If the installation is hard to reach, the same GFR series is available with an automatic drain (code A) or a differential-pressure drain (blank) that discharges condensate without attention.
