Findeva Pneumatic Piston Vibrators
FP Series and FPLF - No Lube Series

About Findeva Piston Vibrators

Piston vibrators use the impact action produced by a moving piston to flex the bin wall. This flexing action loosens material stuck to the wall, allowing gravity to restore material flow. The linear force that is produced works well for material feeding and screening applications.

Findeva piston vibrators are Air-Cushioned piston vibrators only. They use a cushion of air to dampen the piston movement, so the piston reverses direction before impacting the vibrator base. Therefore, Findeva piston vibrators are more quiet than the Impacting piston vibrators (piston actually impacts the base of the vibrator). For more information please see:

Advantages of Findeva Piston Vibrators

  • Long Life - Anodized aluminum body and leaded bronze piston provide corrosion resistance and minimize piston and cylinder wear for extended life.
  • Small, Lightweight - Hard anodized aluminum alloy body.
  • Trouble-Free Operation - No required maintenance if using filtered air for the FPLF models and filtered lubricated air for the FP Series.
  • Spring ensures reliable start-up in all mount orientations.
  • No lubrication needed for the FPLF series.
  • Clean Operation - FPLF models produce no oily mist because no lubrication is required. Special piston treatment is self-lubricating.
  • FPLF Pistons meet FDA guidelines. Designed specially for the pharmaceutical and food industries.
  • Quiet Operation - Expertly designed exhaust system absorbs sound producing only 60-75 dBA. Much more quiet than other pneumatic vibrators.
  • Air-Cushioned Models - Quieter than Impacting Models because a cushion of air eliminates metal-to-metal impact.
  • Highly Efficient - Use less than 6 CFM, even for largest models.
  • Easy to Mount - Threaded base for mounting.
  • Versatile - Easy to control force and frequency by adjusting air supply.

    • FRGL - Includes airline filter, lubricator, and pressure regulator with gauge for all FP models.
    • FRG - Includes airline filter and pressure regulator with gauge models for all FPLF models.
  • Sirometer - Convenient, compact rpm meter for measuring vibrator speed.

Vibrator Selection

Since piston vibrators create material flow by flexing the bin wall, selection of the proper vibrator is based on the bin wall thickness. The thicker the wall the bigger the vibrator needed. If selecting a more quiet Air-Cushioned model you generally use one size larger than an Impacting model sized for the same application. Selection is also based on the combined weight of the chute or moving part of screen and the material inside. Please see:
