The AirTAC GFR20008MLC3T AirTAC Filter Regulator NPT1/4 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 GFR20008MLC3T is an AirTAC GFR200 filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the 200 size with a 1/4 in NPT port, a manual drain bowl in polycarbonate, the standard 40 um filter element, and the low-pressure regulator type for circuits that run at reduced pressure. It is fitted with an external round gauge reading in bar and includes a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans the 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in and PT, G or NPT threads. Drain, filter grade, gauge and scale choices vary by model code. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet 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. |
| 3 | Gauge scale: bar. 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. |

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 conditions and holds reduced clamping pressure on jig and fixture circuits, keeping chips and condensed water out of the clamp cylinders while the operator reads set pressure on the bar gauge.
On food and carton packaging conveyors, the unit filters carryover moisture from the shop air and regulates the lower pressure that pusher and gate cylinders need, with the manual drain emptied during shift checks.
Benchtop sample handlers and small test rigs that run at reduced air pressure use this low-pressure type filter regulator to clean the supply and set a gentle, repeatable pressure for grippers and actuated valves.
Start with the port step: the 200 size carries 1/4 in ports, and the larger 300/400/600 bodies step up in port and flow capacity, so match the size to your line's air demand. Choose the drain type to suit access: manual drain (this model) for attended installations, automatic or differential-pressure drain where the unit is hard to reach. Pick the 40 um standard element for general air preparation or the 5 um (W) element for finer protection, and select the gauge scale you want to read: MPa, psi or bar. Thread is PT as standard with G and NPT as order options; a bracket is included on this model. Because flow is published only as curves and not as a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order.
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 the GFR series as performance curves, not as a single rated number, so we do not quote a figure here. Tell us your application and line pressure and we will confirm the flow data from the datasheet on request before you order.
In the code GFR20008MLC3T, the M position sets a manual drain: the bowl must be drained by hand, which suits attended installations. The C and 3 positions set the external round gauge with a bar scale; square embedded gauges and MPa or psi scales are available on other codes in the series.
