The AirTAC GFR60020LNWTK AirTAC Filter Regulator NPT3/4, 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 PT3/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60020LNWTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit has 3/4 in NPT ports, a 5 um filter element (the finer W grade), a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, and a low-pressure regulator type for circuits that run below standard working ranges. The aluminium alloy bowl suits the larger 600 frame, a reverse/check valve is fitted to hold downstream pressure, and a mounting bracket is included. No gauge is fitted on this code.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge options, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the exact low-pressure adjustment range against 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.

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Feeds filtered, regulated air to carton-sealing and case-erector cylinders that run at reduced pressures, with the 5 um element keeping spool valves clean and the check valve holding the circuit during supply dips.
Provides clean, gently regulated air to bench apparatus and pilot-operated instruments where a low-pressure regulator type is required and fine 5 um filtration protects sensitive pneumatic controls.
Supplies filtered air to diaphragm and quarter-turn valve actuators on a process skid, with the differential-pressure drain clearing condensate automatically and the reverse/check valve maintaining actuator pressure if the main supply drops.
Start with size and port: 600 is the largest GFR frame, and this code carries 3/4 in NPT ports - step up or down (200/300/400/600) to match the pipe and required flow. Choose the drain: differential-pressure (this unit) drains on pressure rise, automatic drains on a timer-free cycle, manual requires operator action. Choose the filter grade: 40 um is standard, 5 um (this unit, code W) protects finer downstream components. Add a gauge with MPa, psi or bar scale if you need a setpoint reference - this code ships without one. Thread is PT as the AirTAC standard; G (BSPP) and NPT (this unit) are order options. Brackets are included unless the J code is specified. Because flow is published as curves, not a single rated figure, send us your application parameters and we will confirm the right size before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. 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 figure, so we do not quote a number that could mislead your sizing. Send us your line pressure, downstream demand and acceptable pressure drop, and we will confirm the flow figures from the datasheet for this exact 600-size, 3/4 in NPT configuration before you order.
The W in the code specifies the finer 5 um filter grade instead of the 40 um standard, which suits circuits protecting sensitive valves and instruments. The N code means no gauge is fitted; if you want a setpoint reference, we can quote the same unit with an embedded square gauge in MPa, psi or bar scale.
