The AirTAC GFR20008MLC2WG AirTAC Filter Regulator G1/4 5um Manual Drain is a genuine G-series filter regulator: water separation, 5 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 GFR20008MLC2WG is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This 200-size unit is fitted with a 1/4 in port in G (BSPP) thread, a 5 um filter element (code W, finer than the 40 um standard), a manual drain bowl in PC (polycarbonate), a low-pressure regulator type, and an external round gauge with a psi scale. A mounting bracket is included and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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. |
| (blank) | No reverse-flow valve (the default). |
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.

A low-pressure filter regulator feeding clamping cylinders on a fixture line: the 5 um element keeps fine particles out of the clamp valves while the regulator holds the lower circuit pressure the clamping sequence is set up for.
On a small CNC or lathe with air-assisted tooling or part-ejection cylinders, this 1/4 in unit filters condensed water and fine dust from the shop air and regulates it down to the pressure the actuator circuit was designed around.
A branch supply on a packaging or labelling machine where sensors, small air jets or low-pressure cylinders need cleaned air at a reduced, stable setting - with the psi gauge giving operators a visible setpoint at the machine.
Start with the port step: 200 size in 1/4 in suits lighter air circuits; step up to 300, 400 or 600 if the circuit demands more flow capacity. This unit carries the 5 um element (code W) - choose it where finer particulate removal matters, or specify the 40 um standard grade where it does not. The manual drain means an operator opens the bowl drain periodically; if you prefer automatic or differential-pressure draining, those variants exist in the same family. The round psi gauge is fitted here; embedded square gauges and MPa or bar scales are the alternatives. PT is the standard thread, with G and NPT as orderable options, and a bracket option is available across the family. 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow and sizing from the datasheet on request before you order.
The M in the code sets a manual drain: an operator opens the bowl drain periodically to remove collected water, instead of relying on an automatic or differential-pressure drain. The L sets the low-pressure regulator type, intended for circuits regulated below standard ranges; the exact adjustment range for this variant is not published, so we confirm it from the datasheet on request.
