Whisper Loaders

Pneu-Con Whisper Loaders

Self-Contained Vacuum Loader Conveying Systems

Whisper Loader is a stand-alone vacuum loader conveying system with easy operation, low maintenance and easy cleaning.

Pneu-Con's Whisper Loaders are self-contained vacuum loader conveying systems which operate automatically to maintain a constant material level in day bins or a receiving hopper, which can be located above injection, extrusion or blow molding machines. Each self-contained Whisper Loader vacuum loader operates on a batch principle. The control panel is equipped with a PLC-type controller module with adjustable (programmable) timer functions to control all timer-related loader functions. The duration of the conveying (run-time) and dump cycle (dump-time) can be adjusted to suit the application using the controller settings.

Whisper Loader Vacuum Loader Packages

Standard Whisper Loader packages include a vacuum loader with a standard brush-type integrated motor/turbine, material pick-up lance (sized to match line size of loader inlet), 10-ft or 20-ft length of clear PVC flexible hose (sized to match, depending on model) with a pair of hose clamps and control panel.

As an option, Whisper Loaders can be supplied with a Vibra-Pulse filter cleaning system to automatically clean the filter following each conveying cycle. With 0.25 to 4.25 cubic ft. capacities, Whisper Loader vacuum loaders can be fitted for gravimetric applications. Adding a high-level probe and slide gate will allow you to refill material with a signal from a feeder.
