Engineered Air Knife Drying Systems

How can 2psi replace 60psi?

Guaranteed performance that gets your product dry

It takes both air volume and velocity to produce blow-off force.  Velocity breaks the surface tension while sufficient air volume delivers that velocity to the product.

A highly efficient, effective low-pressure air knife system offering staggering savings over compressed air.  Sonic drying systems delivers clean, dry, heated air which can assist with evaporation.
