The AirTAC GFR20006LF2TK AirTAC Filter Regulator NPT1/8 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 AirTAC GFR20006LF2TK is a GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure in a single compact body. This 200-size unit carries a 1/8 in NPT port, the standard 40 um filter element, a differential-pressure drain, a low-pressure regulator, an embedded square gauge scaled in psi, and a reverse (check) valve. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the polycarbonate bowl shows collected condensate at a glance; a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, gauge scale options, and G (BSPP) or NPT threads as order options. Flow is published as curves rather than a single rating, so ask us to confirm 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. 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.

| 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. |

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.

Point-of-use conditioning for the pneumatic clamps and tool-changer actuators on a CNC machining centre: the 40 um element strips water and condensate before it reaches precision components, while the low-pressure regulator holds a gentle, stable supply and the psi gauge gives operators a visible setpoint.
Conditioning the air feeding a packaging line's conveyor diverters and sorting gates. The built-in check valve holds downstream pressure if the supply dips, protecting the stroke timing of the diverters, and the differential-pressure drain clears collected water without interrupting the shift.
Supplying regulated air to a laboratory analytical instrument or pneumatic test bench that runs at low pressure: the 40 um filtration protects delicate control valves from particulate, the square psi gauge allows careful setting, and the check valve prevents backflow into the bench circuit.
Size and port step up together: 200 with a 1/8 in NPT port suits lighter duty, while 300, 400 and 600 move more air - match the size to your demand. Choose the drain: differential-pressure (as here), automatic for unattended draining, or manual where you want to drain by hand. Pick the 40 um standard element or the 5 um (W) grade for finer protection, and a gauge scale in MPa, psi or bar. PT is the standard thread; G (BSPP) and NPT are 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand, and we will confirm the flow from the datasheet for this 200-size, 1/8 in NPT unit before you order.
The L marks the low-pressure regulator type, intended for circuits that run below standard line pressures. The exact adjustment range for the low-pressure type is not published in the standard table, so ask us to confirm the range against your setpoint before ordering.
