The AirTAC GFR600-20 AirTAC Filter Regulator PT3/4, 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 automatic 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 GFR600-20 is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in one body. This size-600 unit is threaded PT3/4 and carries a 5 um filter element (code W), an automatic drain that expels collected condensate without manual attention, and a round pressure gauge reading in psi. A reverse/check valve is fitted, and the aluminium alloy bowl suits this largest G-series frame.
This is a genuine AirTAC part, drawn from a range spanning sizes 200 to 600 with ports from 1/8 to 1 inch, manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge scales in MPa, psi or bar. AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we confirm sizing and datasheet figures on request before you order.

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 0.15 - 0.9 MPa (20 - 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 spray booth supply line, the 5 um element and a steady regulated setpoint support consistent finish quality, while the automatic drain clears condensate from the bowl between shifts without operator attention.
On the 3/4 inch air main of a palletizer or case sealer, the regulator holds set pressure for cylinders and grippers, and the fitted check valve keeps the downstream circuit charged during brief upstream dips.
On the shop-air main feeding a plasma cutting bench, this unit filters and regulates the supply to the torch console, with the round psi gauge giving the operator a local pressure readout at the machine.
Choose the size and port against the air demand of the line: this is the 600 frame with a 3/4 inch PT thread, the largest step in the range, so it belongs on main lines and high-consumption drops rather than point-of-use take-offs. The 5 um element (code W) suits downstream instruments and spraying where the standard 40 um grade is too coarse, and the automatic drain keeps the aluminium alloy bowl clear of condensate in attended plant. The round psi gauge gives a local readout, and the fitted check valve holds the downstream circuit if upstream supply dips. Thread is PT as standard; G (BSPP) and NPT are order options. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFR-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your operating pressure and air demand and we will confirm sizing against the datasheet on request.
The automatic drain (code A) expels collected condensate without anyone opening the aluminium alloy bowl, which suits attended plant and hard-to-reach mains. The 5 um element (code W) is one grade finer than the 40 um standard, a common choice ahead of spraying and instrumentation. Both are as-decoded features of this model.
