The AirTAC GFR20006LF2GK AirTAC Filter Regulator G1/8 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR20006LF2GK is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates the pressure delivered downstream. This size-200 configuration has a G1/8 (BSPP) port, the standard 40 um filter element, a differential-pressure drain, the low-pressure regulator type, an embedded square gauge scaled in psi, and a built-in reverse-flow check valve. The polycarbonate bowl shows collected condensate at a glance, a mounting bracket is included, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus options for automatic or manual drains, a 5 um element (code W), gauge scale, and thread. AirTAC publishes flow only as curves rather than a single rated figure, so we do not quote a number here - ask us and we will confirm the datasheet figures for your application on request.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. 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.

|---|---|
| 06 | Port size PT1/8". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| 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. |
| 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.

Feeding filtered, low-pressure regulated air to the sealing and wrapping actuators on a horizontal form-fill-seal line, with the built-in check valve blocking reverse flow if the supply dips.
Conditioning bench compressed air for lab instruments that need clean air set at a low pressure, with the psi-scaled square gauge giving a direct reading for repeatable settings.
Supplying clean, regulated low-pressure air to blow-off nozzles that clear dust and light chips from a conveyor line without disturbing lightweight parts.
The real choices on this family: step up from size 200 (G1/8 here) to 300, 400 or 600 as your flow demand grows - larger size means larger port and more flow capacity. Drain comes as differential-pressure (this unit), automatic (A) or manual (M). The standard element is 40 um; specify W for 5 um. The embedded square gauge is available in MPa, psi or bar scales (this one is psi), and an external round gauge is optional. Thread on this unit is G (BSPP); PT is the standard thread and NPT is an order option. A mounting bracket is included, and the L in the code marks the low-pressure regulator type. One honest note: flow is published as curves, not a single rating, and the low-pressure type's adjustment range is not in the published table - ask us to confirm both 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 a number. Tell us your application and we will confirm the datasheet flow curve and correct sizing for you on request before you order.
It marks the low-pressure regulator type, as opposed to the standard version. The exact adjustment range for the low-pressure type is not published in the catalogue, so we confirm it on request. Everything else decodes normally: 1.0 MPa (145 psi) maximum inlet pressure, -5 to 70 C operation, 40 um filtration and a differential-pressure drain.
