AirShield optical sensor protection nozzle

Try It Yourself

See the effect, live.

A simplified simulation of an inspection line — dust accumulates on the sensor's lens exactly like it would in a dusty manufacturing environment. Press and hold the button to see AirShield clear the view.

Watch dust build up on the sensor's lens as parts pass on the line. Press and hold Activate AirShield to purge the lens and restore a clean, reliable read.

About OCHI Automation

Built from the plant floor up.

We don't just program controllers — we understand the production environment they live in.

OCHI Automation LLC is a small, focused engineering firm based in the Auburn / Sumner area of Washington State. We work with manufacturers in the Pacific Northwest who need reliable, practical automation — not overengineered systems that are hard to maintain.

With hands-on experience in industrial production lines, laser measurement systems, and machine vision, we bring a plant-floor perspective to every project. That means we design for operators, not just engineers — clear interfaces, robust logic, and systems that actually get used.

We also develop our own industrial products, including AirShield — a Coanda-effect air purge system that protects laser-and-camera sensors (LMI Gocator, ifm, Keyence, and more) in dusty manufacturing environments. It has been deployed and field-proven since 2024.

We're a small, focused team. You'll talk to the engineer who will actually work on your project — not a project manager who passes things along. We take a limited number of clients at a time to keep it that way.
