The AirTAC AirTAC GFR20006 Filter Regulator NPT1/8, Manual Drain 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 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 GFR20006 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 200 unit has a 1/8 in NPT port, a 40 um standard filter element, and a manual drain bowl in PC (polycarbonate). It is the low-pressure type, so it is intended for circuits that run below standard regulator settings; the exact adjustment range is not published, so confirm it with us for your setpoint. An embedded square gauge scaled in MPa is fitted, a reverse/check valve is built in, and a mounting bracket is included. 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 is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, a 5 um (W) element option, gauge and scale choices, and G (BSPP) or NPT thread options in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm flow and 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.

|---|---|
| 06 | Port size PT1/8". 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). |
| F | Gauge shape: Square. 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.

On a lab bench running pneumatic test fixtures, this low-pressure type filter regulator cleans the shop air line and holds a gentle, stable supply pressure to sensitive instruments and small actuators, with the MPa gauge giving a clear local reading.
At a CNC workholding station, the unit filters water and chips-carried moisture out of the supply and regulates pressure to the clamp cylinders, while the check valve helps hold the set circuit if the upstream air dips.
On a packaging line driving small pusher and divert cylinders, this filter regulator conditions the air at the point of use and lets the line set a low operating pressure, with the manual drain emptied during scheduled changeover.
Start with the port step: this unit is size 200 with a 1/8 in NPT port; larger sizes (300/400/600) step up to 1/4 in through 1 in and suit higher air demand, so match the size to the line rather than oversizing on guesswork. Drain choice matters: this configuration is manual drain, meaning someone drains the bowl on a routine; automatic or differential-pressure drain versions exist if the installation is unattended. The 40 um element is standard; specify the W code if the application needs the 5 um grade. The fitted square gauge reads in MPa; psi and bar scales are order options, as is an external round gauge. PT is the standard thread; G (BSPP) and NPT are catalogue options ordered by code, and a no-bracket (J) variant exists. Flow is published as curves, not a single rating, so send us your air demand 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. The reflux valve permits reverse flow 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 here. Tell us your line pressure and air demand and we will confirm the flow and full datasheet figures for this exact model on request before you order.
This configuration carries the M code, so condensate collected in the PC bowl is released by hand on a routine. If the installation runs unattended, the same filter regulator is available with an automatic (A) or differential-pressure (blank) drain - just order the corresponding code.
