The AirTAC GFR20008MLC2WK AirTAC Filter Regulator, PT1/4, 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 AirTAC GFR20008MLC2WK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body, so one component does both jobs at the point of use. This 200-size unit is threaded PT1/4 (1/4 in) and carries the W-coded 5 um element for finer filtration than the standard 40 um grade. Drain is manual (M code): the bowl is emptied by opening the drain when you choose, which suits installations that are checked as part of a routine. The regulator is the L-coded low-pressure type, and the C2 code adds an external round gauge reading in psi. A reverse/check valve (K) is fitted, and the mounting bracket is included. The polycarbonate bowl is rated for a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR filter-regulator family, which spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 in up to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um elements, standard or low-pressure regulation, gauge style and scale options, and G (BSPP) or NPT threads as order alternatives to the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for 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.

|---|---|
| 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. |
| (blank) | Mounting bracket included. |

| C | Gauge shape: Round. 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

On a fixture-clamping or workholding line that holds parts at a deliberately reduced pressure, this low-pressure-type filter regulator cleans the supply, holds the set pressure and its check valve keeps the circuit from back-feeding while it does so.
A lab bench or test rig running small pneumatic tools, cylinders and fittings benefits from the 5 um element stripping fine particulate and water from the shop air, with the psi gauge giving a direct readout at the bench.
On a packaging line driving small air cylinders for diverters, pushers and sealing heads, this unit filters and regulates the air at the machine drop, and the manual drain lets operators clear accumulated water during shift checks.
Start with the size and port: the 200 frame with its 1/4 in PT port suits compact circuits, while the 300, 400 and 600 frames step up in port size and capacity for larger air demand. Choose the drain to match how the unit will be serviced: manual (as here) puts emptying in the operator's hands, automatic drains continuously, and the differential-pressure default drains on a pressure drop. Pick the element grade for the job: 40 um is the standard general-purpose grade, and the W-coded 5 um grade (fitted here) protects more sensitive downstream equipment. The gauge can be an embedded square gauge or an external round gauge, in MPa, psi or bar scales; this unit carries a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available to order, and the bracket is included.
Two honest routing notes before you order. First, because this is the L-coded low-pressure regulator type, confirm its adjustment range against your setpoint with us before ordering. Second, flow for this family is published as curves rather than a single rated number, so send us your application details and we will confirm sizing from the datasheet.
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 this family as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Send us your application details and we will confirm the flow and sizing figures from the datasheet before you order.
The M code in GFR20008MLC2WK means the bowl is emptied manually: an operator opens the drain to release accumulated water and oil, which suits installations checked on a routine. The GFR family is also available with an automatic drain (A) or the differential-pressure drain (the default when no drain code is present), so choose the type that matches how often the unit will be attended.
