The AirTAC GFR20006MLF2K AirTAC Filter Regulator PT1/8 Low-Pressure 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 PT1/8" 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 GFR20006MLF2K is an AirTAC GFR200 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built on the size-200 body with a PT1/8 (1/8 in) port, a manual-drain polycarbonate bowl and the standard 40 um filter element. The regulator is the low-pressure type, an embedded square gauge scaled in psi is fitted, and a reverse (check) valve is included; a mounting bracket comes with the unit.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for thread (PT standard; G and NPT to order), drain type, filter grade (40 um standard, 5 um optional), gauge scale and reverse valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Because flow is published as curves rather than a single rating, we confirm datasheet and sizing figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

On a machining-centre fixture circuit, this unit filters the supply air and holds a steady low regulated pressure to the clamping cylinders, with the check valve helping hold the set pressure downstream. The manual-drain bowl suits a cell that is bled down at shift end.
Small packaging-machine cylinders and grippers need clean, moisture-reduced air at a stable low setting. A size-200 filter regulator mounted at the machine inlet does that job in one body, with the psi-scaled square gauge giving the operator a direct setting reference.
Lab and test rigs fed from a shop-air drop often need gentle, low regulated pressure to instruments and small air bearings or cylinders. The low-pressure regulator type, 40 um element and included bracket make this a compact point-of-use prep unit at the bench.
The real choices on this family are the size and port step, drain type, filter grade, gauge and thread. Size 200 with a PT1/8 port is the smallest step; move up through 300, 400 and 600 as your flow demand and piping grow. Drain here is manual (code M): the bowl is emptied by hand, which suits installations that are checked regularly - automatic and differential-pressure drains are available in the family for hands-off condensate removal. The element is the 40 um standard grade; a 5 um element (code W) is offered where finer filtration is needed. The fitted square gauge reads in psi (MPa and bar scales are alternatives), and the thread is PT, with G (BSPP) and NPT as catalogue options to order. 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 G-series flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details - pressure, downstream consumption and piping - and we will confirm the flow curves and correct sizing from the datasheet on request.
Code M means the polycarbonate bowl is drained by hand: you open the drain to expel the condensate that has collected. It suits installations that are checked regularly, such as a machine bled down at the end of a shift. If you need hands-off removal, the GFR family also offers automatic and differential-pressure drain options.
