The AirTAC GFR60020LF2WT AirTAC Filter Regulator 3/4 in NPT, 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 GFR60020LF2WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit is fitted with a 3/4 in NPT port, the fine 5 um filter element (code W), a differential-pressure drain that bleeds accumulated condensate automatically as flow passes through, and an embedded square gauge reading in psi. It is the low-pressure (L) type, and the size-600 bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and offers choices of drain type, 40 um or 5 um filtration, standard or low-pressure regulation, gauge type and scale, thread form (PT standard, G and NPT as options) and bracket fitting. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers for your application on request.

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.

| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Clean, regulated air ahead of a directional-valve manifold on a packaging or assembly machine, where the 5 um element protects spool clearances and the square psi gauge gives operators a setpoint they can read at a glance.
A 3/4 in NPT supply point feeding a production line section that runs at reduced pressure, with the differential-pressure drain handling condensate drop-out and the aluminium bowl suiting the main plant-air header.
Circuits driving diaphragm pumps, air tables or clamping fixtures that must not see full line pressure - the low-pressure (L) type regulator keeps the working band where those devices need it.
Step up or down the size ladder (200 / 300 / 400 / 600) to match your port and flow band - this unit sits at the top of the range with a 3/4 in NPT port. Choose the drain to suit access: differential-pressure (as here, no operator input), automatic, or manual. Choose the element: 40 um standard for general protection, 5 um (this unit) where downstream equipment needs finer air. Pick the gauge scale you read in - MPa, psi or bar - and the thread form: PT is the standard, with G (BSPP) and NPT orderable. A mounting bracket is included with this configuration.
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated figure, so we cannot quote you a number here. Send us your application details and we will confirm the sizing against the datasheet curves on request.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR family as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your application - supply pressure, set pressure and expected air demand - and we will confirm the relevant flow figures from the datasheet on request before you order.
The W code in GFR60020LF2WT selects the optional 5 um element instead of the 40 um standard, giving finer particulate removal for sensitive downstream equipment. The blank drain position is the differential-pressure type: it bleeds off collected condensate automatically as air flows through, with no manual draining routine - useful where the unit is mounted in a position that is awkward to reach.
