The AirTAC GFR200-06NPT AirTAC Filter Regulator, 1/8 in NPT 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 PT1/8" 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 GFR200-06NPT is a filter regulator: one body that removes water and particulate from compressed air and sets downstream pressure, so a single 1/8 in NPT unit handles both air preparation jobs. This configuration is fitted with the fine 5 um filter element (code W) instead of the 40 um standard element, a manual drain on the bowl, and a built-in reverse/check valve (code K) that holds downstream pressure when the upstream supply is lost. No gauge is fitted (code N), so add a gauge separately if a visual pressure reading is needed at the point of use. The pressure bowl on this size 200 unit is PC (polycarbonate), and the setting range is 0.05-0.9 MPa (7-130 psi) with the manual-drain version. 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 from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and is offered with manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge options and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.

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.

Feeding a small pneumatic press or clamping fixture: the 5 um element keeps fine debris out of the press valve, the regulator sets the working pressure for consistent forming, and the check valve holds the set pressure if the shop supply drops mid-cycle.
Point-of-use supply to a packaging machine's control valves: filtration plus regulation in one 1/8 in NPT body saves panel space, the manual drain is emptied at shift checks, and the compact size 200 footprint fits tight cabinets.
Supplying air to laboratory automation or analytical instrument actuators: the 5 um grade suits sensitive pilot valves, the regulator holds a stable low setting in the 0.05-0.9 MPa range, and the PC bowl allows visual checks during maintenance.
Start with the port and size step: size 200 with a 1/8 in NPT port suits compact supply lines, and larger sizes (300/400/600) move up in port and capacity - match the step to the flow your line needs, which we can confirm against the published curves. Choose the drain: manual (this unit) means an operator drains the bowl; automatic or differential-pressure drain suits points that cannot be attended regularly. Choose the element: 40 um standard for general protection, 5 um (this unit, code W) where downstream valves or instruments need finer filtration. Decide on a gauge and its scale (MPa, psi or bar) - this unit ships without one - and on thread: PT is the standard, with G (BSPP) and NPT as catalogue options to order. A mounting bracket is included on this configuration.
One honest note on sizing: flow for the GFR series is published as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet figures and the right size 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 the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and line conditions and we will confirm the datasheet flow curves and check the sizing against your required flow before you order.
The M in the code GFR20006MNWTK specifies a manual drain: an operator opens the drain at the bowl to remove collected water. If the installation cannot be attended regularly, the same GFR200 size is available with an automatic drain (code A) or a differential-pressure drain (blank) - note the regulation range differs by drain type, with manual-drain units setting from 0.05 MPa (7 psi) and auto/differential units from 0.15 MPa (20 psi), both up to 0.9 MPa (130 psi).
