The AirTAC GR200-08LF2TK AirTAC Air Pressure Regulator NPT1/4 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT1/4" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The AirTAC GR200-08LF2TK is a 200-size air pressure regulator in the GR series: its only job is to hold a steady downstream air pressure, and it does nothing else - no filtration, no bowl, no lubrication. This configuration is the low-pressure type, adjustable up to 0.4 MPa, with a 1/4 in NPT port, a built-in reverse (check) valve, and a square pressure gauge reading in psi fitted as standard. The body mounts with the included bracket, and GR regulators of this size can also be panel-mounted.
This is a genuine AirTAC part. The GR series spans 200/300/400/600 sizes with port sizes from 1/8 to 1 inch, standard or low-pressure adjustment, gauge or no-gauge builds, optional external round gauges, and PT, G or NPT threads. We do not quote a single rated flow figure because AirTAC publishes flow as curves; ask us and we will confirm the datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. 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". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |
| (blank) | Fixing 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. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with 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 rather than from a single rated figure.

On a fixture-clamping line where workpieces must be held gently, this low-pressure GR regulator holds a reduced, steady downstream pressure to the clamp cylinders, with the check valve helping hold the set point if upstream supply dips.
Feeding the light-touch sealing or tucking cylinders of a carton or bag packaging line, the regulator keeps the actuation pressure stable so seals are consistent, and the psi gauge lets operators verify the setting at a glance.
At a bench drop serving air-operated lab apparatus, this unit steps the building supply down to a gentle, repeatable pressure for sensitive pneumatic tools and instruments, with the included bracket mounting it neatly at the bench.
Start with the port step: this unit is 200 size with a 1/4 in NPT port, and the GR range steps up through 300/400/600 to 1 inch - pick the size that matches the line and the flow your circuit needs. This is the L (low-pressure) type, so choose it where the working pressure stays within the low-pressure adjustment range rather than the standard GR range. The square gauge here reads in psi; MPa and bar scale options exist if your crew prefers them. Thread is NPT on this code - PT is the AirTAC standard and G is also orderable - and the K code means a reverse/check valve is already fitted. A mounting bracket is included. Because flow is published as curves rather than one rating, ask us to confirm sizing against your application before you order.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes GR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your circuit needs, and we will confirm the datasheet flow curves for this 200-size, 1/4 in NPT regulator on request before you order.
The L in the code marks the low-pressure regulator type, adjustable up to 0.4 MPa, suited to circuits that never need standard-range settings. The fitted square gauge reads in psi; MPa and bar scales are orderable options. Thread is NPT on this code - PT is the AirTAC standard and G (BSPP) is also available to order as a specification choice.
