The AirTAC GFR20008MLC3TK AirTAC Filter Regulator 1/4 in NPT 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 AirTAC GFR20008MLC3TK is a GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This 200-size unit is fitted with a 1/4 in NPT port, a manual drain bowl in polycarbonate, the standard 40 um filter element, a low-pressure regulator type, an external round gauge reading in bar, and a reverse (check) valve. The mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um filter element (code W), embedded square or external round gauges with MPa, psi or bar scales, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

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.

A bench-mounted clamping fixture that holds parts while an operator drills or fits components needs clean, regulated air at a modest set pressure. This filter regulator conditions the supply line at the fixture, the 40 um element keeps debris out of the clamp cylinder, and the check valve holds the downstream circuit if the upstream supply is interrupted.
Pneumatically actuated butterfly or ball valves on a process skid rely on a stable pilot-air signal to position correctly. Feeding the actuator pilot line through this unit filters water and particles from the plant air, regulates the pilot pressure, and the bar-scale gauge lets a technician verify the set point at a glance during rounds.
A lab bench running pneumatic test stations needs air that is dry, clean and held at a controlled, often reduced, pressure. This low-pressure type filter regulator at the rig inlet handles that job, the manual drain suits a supervised environment where the bowl is emptied during daily checks, and the bracket secures the unit to the rig frame.
Start with the size and port: the 200 series with a 1/4 in NPT port suits compact circuits, and stepping up to 300, 400 or 600 gives larger ports and more flow capacity. This unit's low-pressure regulator type is intended for circuits that run below standard regulating ranges; the exact adjustment range for the low-pressure type is not published on the sheet we work from, so confirm it with us against your set pressure before ordering. The manual drain means an operator opens the bowl drain periodically, which suits points of use that are checked routinely; automatic or differential-pressure drains are available if the unit will be left unattended. The standard 40 um element covers general air preparation, with a 5 um element (code W) as an option for finer filtration. The round gauge fitted here reads in bar, and MPa or psi scales can be ordered instead. Thread is NPT as coded, with G (BSPP) and PT as order options, and a bracket is included for panel or surface mounting.
Because flow is published as curves and not as a single rated figure, 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. 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 rather than a single rated figure, so we do not quote a rated flow number. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code GFR20008MLC3TK specifies a manual drain. An operator opens the drain at the bottom of the polycarbonate bowl to release collected water, which suits points of use that are visited regularly. If the unit will be left unattended, the same family is available with an automatic drain (code A) or the default differential-pressure drain instead.
