The AirTAC GFR20008MNWTK AirTAC Filter Regulator NPT1/4 5 um 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 GFR20008MNWTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body, sized 200 with a 1/4 in NPT port. This configuration carries the 5 um filter element (code W) for finer air cleaning than the standard 40 um grade, a manual drain on the bowl, and a built-in reverse/check valve (code K) that holds downstream pressure when the upstream supply is removed. No gauge is fitted (code N), so add an AirTAC gauge separately if a visual setpoint is needed. The polycarbonate bowl is protected by the standard bowl guard, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with manual drain is 0.05-0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR200 size family, one of four sizes (200/300/400/600) that step up in port and flow capacity. Across the GFR range you can order 40 um or 5 um filtration, differential-pressure, automatic or manual drains, gauge or no gauge, PT, G or NPT threads, a low-pressure regulator type, and a reverse/check valve. Published flow data for this series is given as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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 filtered, regulated air to the tool-clamp and coolant-spray circuits of a CNC machining centre, where the 5 um element protects fine solenoid valves and the check valve holds clamp pressure if the shop supply drops.
Conditioning air for the diverters, pushers and sealing cylinders on a food or carton packaging line, with the regulator set to the pressure the actuator manufacturer specifies and the manual drain emptied at shift checks.
Supplying clean, regulated air to the gripper and vacuum-generator circuit of a pick-and-place robot cell, where the 5 um grade keeps the vacuum ejector ports clear and the bracket mounts the unit beside the cell valve manifold.
Start with the port step: the 200 size in 1/4 in suits compact circuits, while GFR300, GFR400 and GFR600 move up in port and capacity - match the size to the flow your line needs rather than to the pipe alone. This unit already carries the 5 um element; choose 5 um where downstream valves and cylinders need finer protection, or the standard 40 um where coarse water and particle removal is enough. The manual drain here means an operator opens the drain periodically - choose automatic or differential-pressure draining where the unit is hard to reach. No gauge is fitted, so add one (square embedded or external round, MPa/psi/bar scale) if operators need to see the setpoint. The NPT thread is the order option; PT is the catalogue standard and G (BSPP) is also available. A mounting bracket is included.
Flow for this series is published as curves, not a single rated number, so send us your application details and we will confirm the datasheet figures and correct sizing 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 rather than a single rated figure, so there is no one l/min or SCFM number we can quote honestly. Send us your application - inlet pressure, downstream demand and acceptable pressure drop - and we will confirm the datasheet curve and check the 200 size in 1/4 in is correctly sized before you order.
This unit's code specifies a manual drain: an operator opens the drain valve periodically to expel collected water. That suits accessible mounting points with regular maintenance rounds. If the unit will sit in a hard-to-reach spot or run unattended, order the automatic drain (code A) or the differential-pressure drain (blank) instead - the regulator adjustment range also widens to 0.15-0.9 MPa (20-130 psi) with those drain types, versus 0.05-0.9 MPa (7-130 psi) with manual drain.
