The AirTAC GFR20008MLC1TK AirTAC Filter Regulator NPT1/4 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 PT1/4" 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 GFR20008MLC1TK is a GFR200-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the 200 size with 1/4 in NPT ports, a manual drain bowl in polycarbonate, a 40 um standard filter element, and the low-pressure regulator type. It is fitted with an external round pressure gauge scaled in MPa, a reverse/check valve, and includes a mounting bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family spans the 200, 300, 400 and 600 sizes with a choice of ports, thread types (PT standard, G and NPT as orderable options), drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge styles and scales, and standard or low-pressure regulation. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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.

|---|---|
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Filtered, regulated air to the clamp cylinders on a CNC fixture, where the low-pressure regulator type holds a gentler clamping circuit and the 40 um element keeps debris out of the clamp valves.
A conditioning point for the air feeding diverters, pushers and gripper cylinders on a packaging conveyor, with the manual drain bled during shift checks and the MPa gauge giving a clear setpoint reference.
Clean, regulated air for bench-top test rigs and pilot rigs running at reduced pressure, where the low-pressure type, round MPa gauge and check valve keep the circuit stable and protected.
Choose the size and port step against the air consumption of the downstream circuit: this unit is the 200 size with 1/4 in NPT ports, and larger sizes step up in port and flow capacity. Drain choice matters: manual drain (as here) needs periodic bleeding, while automatic or differential-pressure drains suit unattended installations. Filtration is 40 um as standard; specify the W option for 5 um where finer protection is needed. Gauge options are the embedded square gauge or an external round gauge, scaled in MPa, psi or bar (this unit has a round MPa gauge). Thread is PT as standard, with G (BSPP) and NPT as catalogue options; brackets are available where panel or wall fixing is needed. 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 this 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 flow and datasheet figures for the GFR200 at 1/4 in NPT on request before you order.
The L code marks this as the low-pressure regulator type rather than the standard type; the exact regulation range for the low-pressure type is not published, so ask us to confirm it. The M code is the manual drain: the bowl is bled by hand, unlike the automatic (A) or differential-pressure (blank) drain options in this family.
