The Vortec Air Flow Amplifiers extract exhaust fumes so that technicians can stay warm with frigid outdoor temperatures. With no moving parts to wear out or break down, these components are safe, the company says. These high flow, bladeless blowers take compressed air and amplify it up to 60-fold, in un-ducted applications. They are easily mounted, ducted and moved, with adjustable airflow and output that can be tailored to the project at hand. With no electrical requirements, they can be mounted wherever there is compressed air. Quiet operation meets noise requirements. Aluminum housings are standard, with stainless steel available for aggressive environments.
