Super Air Knife frees metallurgy lab technician's hands

Technicians in a metallurgy lab used a handheld thumb trigger blowoff that hung inside a fume hood to blow water off samples they were testing. They made the process hands-free by installing a Model 110009 9" Aluminum Super Air Knife, actuated by a foot valve. This not only sped up the process, but it also made it markedly quieter.
