100% seal-welded body, in aluminum or stainless steel with smooth internal finish, boxed-tangential material inlet. Material Pick-Up: Adjustable Aluminum Pick-up Lance & 15-ft flexible hose.
Components
Standard vacuum source is a durable, long-life brush-type motor. Tangential discharge.
Flat-Disc polyester felt filter with food-grade rubber gasket (seals cover to body).System & Controls
Pneu-Vue PLC-based Control Panel, NEMA 1 Hinged Enclosure. Standard voltage 120VAC/10/60Hz. Mounting flange and 6”discharge spout.
Set-up
Spun aluminum cover assembly with motor-mount tabs and integral air-blast pipe with Vibra-Pulse automatic filter-cleaning system.
Grain conveying system - How it works
Self-Contained Grain Whisper Loaders give you the flexibility to transfer grains from a bag, super sack, or box to the mill, then to the grist case and the mash tun/brew house.


Challenges and Solutions
These systems are flexible, fully assembled and ready for your immediate use. Start with a few stations, then add stations and optional equipment as needed, to economically scale upward as your needs change and demand grows.
Portability requirements
Product movement can be dangerous and tedious. We offer portable feed bin hoppers that allow you to move your products safely and efficiently.
Fragile Products
Our products use speed control as well as a boxed inlet system that helps deduce impact and prevent a breakdown of the materials.
Limited Floor Space
Not every factory has the same amount of space. Our systems are built to work in compact layouts with specially placed side access filters for convenience.
Dust control
Our systems are equipped with primary and secondary filtration systems, and built with high efficiency PTFE filter media that ensure a dust-free environment.
Customize your machinery
- Custom material inlets. Sanitary inlets,
boxed inlets and Ferrule/tri-clamp fittings. - Under 8 Cubic foot volume limit as safe
design in view of NFPA Explosion guidelines. - Explosion proof motors for Class I/II classified areas.
- Various voltage configurations:
120v, 220v, 24V, 460v. - Batching Scale hopper to hold/dispense desired amount of material by weight or volume, by loss in weight or gain in Weight.
- Custom design specific to applications.
- Batch, continuous, or flood fed systems.
- Optional portable bin feeders for self-contained systems.
Options & accessories

Self-Cleaning Filters
Self-Cleaning “Central Filters” are used when receivers do not include primary filtration, or when material is hazardous if escaped from the system. Central Filters include automatic pulse filter cartridge cleaning, self dumping receiver, standard wall or floor frame mount bracket, dust retainer skirt. Choose 3, 4, or 7 pleated filter cartridges.

Portable Hoppers
Pneu-Con's Portable Hoppers are optionally available as an accessory for your Central-Powered Grain Conveying System. Other options and accessories are available including scale hoppers, scale platforms, load cells, and more.

Static Filters
Static Protection Filters are used when the primary filtration is incorporated into each of the powder receivers. Static Protection Filters are furnished with one (1) to three (3) filters. Standard filter enclosures are constructed from aluminum and feature an easy-open cover for quick filter removal and replacement.

Vacuum Breaker Valve
Vacuum Breaker Valves permit automatic switching from vacuum (conveying mode) to atmospheric air. This enables the blower to run continuously, preventing it from having to start and stop at the end of every conveying cycle. Pneu-Con's Vacuum Breaker Valves are solenoid controlled and pneumatically operated.
Frequently asked questions
Some of the advantages of choosing a pneumatic conveying system over a mechanical transport system are adaptability to virtually any site configuration, ease of maintenance, and faster ROI. Pneumatic conveying systems can also move dry bulk materials farther than conventional mechanical systems, at a lower cost.
Pricing for a pneumatic conveying system varies from project to project, and from application to application. We treat every customer’s project as a custom design, but can often put together a bulk material handling solution using standard parts. This approach can save the customer time and reduce overall costs. We can also design and engineer a complete custom pneumatic conveying system based on a customer’s specifications, and for those bulk material applications which have unique requirements.
Pneu-Con can design and engineer any type of bulk material handling system for most applications. We engineer and manufacture pneumatic conveying systems and can integrate our systems with components and controls from other manufacturers.
Our full range of services includes market research, design, engineering, integration, commissioning, startup, repair, parts, maintenance and staff training of complete bulk material processing systems and solutions.
