Whisper Loaders

Pneu-Con’s proven self-contained Whisper® Loaders offers you a complete system that affords ease of operation, and low maintenance, reducing the cost of producing your finished product.


WHISPER® Loaders work automatically to maintain a constant material level in day bins or receiving hoppers which are located above injection, extrusion, or blow modeling machines. Each self-contained system operates on a batch principle. The duration (time) of conveying and dump cycles are pre-determined by adjustable timers.
