Educational Wind Tunnel (EWT)

An easy-to-use, all-in-one fluids / aerodynamics laboratory

Description

The AEROLAB Educational Wind Tunnel (EWT) System is a powerful tool for educators and researchers alike.

With many optional features available, the budget-conscious user can start with a basic system and upgrade as needs change or funding becomes available.

The Complete EWT System is an easy-to-use, all-in-one fluids / aerodynamics laboratory. Optional features include instrumentation, data acquisition, models and probes. Contact AEROLAB and build a system today.

Perfectly scaled for high school or university use, the basic EWT system is also popular with small technical businesses needing an accurate, reliable testing device.
