- Pneumatic Conveying -

Whisper Loaders are self-contained conveying systems that work automatically to maintain a constant material level in storage bins or receiving hoppers which are located above linear net weighing scales or product feeders/counters.

Each self contained system operates on a batch principle. The duration (time) of conveying and dump cycles are pre-determined by adjustable timers.

Ideal for use over F-99 Scales!

The most compact of the Whisper Loader family. It's size and capacity make it ideal for the smaller molding and extruding machines.


The most flexible unit in the WHISPER Loader family. Its size offers the most versatility, and is available in a variety of models including power receivers, proportional loading, vibra-pulse, and InterBlend. The Model SC1500 includes, as a standard, a remote mounted electrical control panel and twelve (12) feet of electrical connector cables.


The powerhouse of the WHISPER Loader line. It has the largest motor conveying capacity, making this loader ideal for larger molding and extruding machines.
