The AirTAC GFR200-08 AirTAC Filter Regulator, NPT1/4, Low-Pressure is a genuine G-series filter regulator: water separation, 40 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 GFR200-08 is an AirTAC GFR200 filter regulator: a single body that removes water and particulate from compressed air and regulates downstream pressure. This configuration has 1/4 in NPT ports, a manual-drain polycarbonate bowl, the standard 40 um filter element, and the low-pressure regulator type. A round pressure gauge with a psi scale is fitted, and no mounting bracket or reverse/check valve is included.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drain, a 40 um standard or 5 um (W) element, gauge and thread options, and bracket choices. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.

Feed the clamp cylinders on a machining fixture through this unit so chips and condensed water are strained out and clamp pressure is set once at the panel and held for the shift.
Mount this filter regulator at the booth drop so moisture and pipe scale are caught before the gun line and the atomising pressure is dialled in at the point of use.
Supply the diverters and seal cylinders on a carton packaging line from this unit, giving the machine its own clean-air point and a local pressure setting independent of the main header.
Size 200 with 1/4 in ports is the entry step of the GFR range; step up to 300, 400 or 600 when the application needs a larger port and more flow. This unit is the low-pressure type (L), so choose it where the circuit works at reduced pressure; ask us to confirm the exact adjustment range before ordering. The manual drain (M) means the bowl is drained by hand, which suits points an operator visits routinely; automatic or differential-pressure drain variants exist if the bowl cannot be checked often. The 40 um element is the standard grade; specify W for the 5 um option. The fitted round gauge reads in psi; square embedded gauges and MPa/bar scales are catalogue alternatives. NPT is ordered with the T suffix, G (BSPP) with G, and PT is the standard thread. Bracket J means no bracket is supplied; omit J where a bracket is wanted. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated number, so we do not quote a figure. Tell us your line pressure and the air demand of the equipment, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code means the polycarbonate bowl is drained by hand: an operator opens the drain when collected water needs emptying. The GFR family is also catalogued with automatic (A) and differential-pressure (blank) drain versions if the installation point is not checked regularly.
