The AirTAC GR20008LC2TK AirTAC Low-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 GR20008LC2TK is an AirTAC GR-series air pressure regulator: it does one job, holding downstream pressure steady from a compressed-air supply. This unit is the 200 size with a 1/4 in NPT port, built as the low-pressure type with an adjustment range of up to 0.4 MPa (58 psi), so it suits circuits that must never see full line pressure. It carries a round pressure gauge reading in psi, a reverse (check) valve so downstream pressure is held if the supply drops, and a mounting bracket; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR family spans the 200, 300, 400 and 600 sizes with 1/8 in to 1 in ports, standard and low-pressure types, gauge and no-gauge variants, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -20 to 70 C, wider than the rest of the G family. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

| 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.

Packaging machines often clamp cartons or trays with air cylinders that must not squeeze too hard. This low-pressure regulator holds the cylinder supply at a gentle setpoint, and the check valve keeps the clamp from shifting if the main air supply dips.
Spray guns and atomizing nozzles need a steady, moderate air pressure to break fluid into a fine mist. Feeding the gun line through this 1/4 in NPT regulator lets the operator set and read the atomizing pressure on the psi gauge without touching the shop main.
Bench-top test rigs and pneumatic instruments need a calm, limited supply rather than full shop pressure. This regulator steps the 1/4 in NPT feed down to a low setpoint, with the round psi gauge giving a direct readout and the bracket allowing tidy panel or wall mounting.
Start with the port step: the 200 size takes a 1/4 in port here, and moving up to 300, 400 or 600 buys larger ports and more flow capacity, so match the size to the air demand of the circuit. The L in this code marks the low-pressure type, limited to 0.4 MPa, so choose it only where the downstream setpoint sits in that band; the standard GR type covers up to 0.9 MPa. This unit ships as coded with a round psi-scale gauge and a reverse (check) valve fitted; other gauge scales (MPa or bar) and a square embedded gauge are available across the range.
Thread is NPT on this model; PT is the standard thread and G (BSPP) is the other order option, so pick the one that matches your fittings. A mounting bracket is included, and GR can also be panel-mounted. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet 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 regulator flow as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Send us your application details and we will confirm the datasheet flow curve and help you check whether the 200 size at 1/4 in NPT suits your air demand before you order.
The L in the code GR20008LC2TK marks the low-pressure regulator type, whose adjustment range tops out at 0.4 MPa (58 psi). It is chosen for circuits that must never see full line pressure. If your setpoint needs to go higher, the standard GR type covers up to 0.9 MPa - tell us your setpoint and we will point you to the right variant.
