Air blaster

They are permanently installed on silos, bins and hoppers for powdery materials, and are used to prevent caking and to allow maximum storage capacity.

They are also used in the film and theatre industries to project simulated debris from explosions, and as surprise effects in Halloween haunts and other attractions.

When the air in the pressure vessel is quickly released, the blast, called the impact force, evacuates material sticking to the container's walls (referred to as "rat holing"), and breaks potential accumulation points for subsequent clogging ("bridging").

An efficient air blaster should be designed to ensure: Usually 2 versions exist A high temperature version: mainly for heat exchanger and cooler applications to remove clogging and to avoid costly plant stoppages and downtime.

A low temperature version: to eliminate build-up and dead stock for powdery and granular materials thus preventing caking and allowing optimization of storage capacity.
