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 blower
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.

pneumatic hopper
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 blower protection filter
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 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.
