The Findeva FP-35-M is a high-performance, linear pneumatic piston vibrator known for its reliability and quiet operation. Manufactured by the Swiss company Findeva, the “M” in the model name indicates that it is a lubrication-free version, making it ideal for food, pharmaceutical, and cleanroom applications.

Key Technical Specifications

The FP-35-M uses a cushion of air to reverse the piston’s direction, resulting in a smooth, linear oscillation without the harsh metallic “clanking” found in some other vibrators.

Core Characteristics

• Linear Vibration: Unlike rotary vibrators that provide an omnidirectional shake, the FP-35-M provides a back-and-forth “shoving” motion. This is excellent for keeping materials moving in a specific direction.

• Adjustability: You can fine-tune the frequency and force simply by adjusting the air pressure via a regulator.

• Quiet Operation: Because the piston is air-cushioned at both ends, noise levels are significantly lower than impact-style vibrators.

• Maintenance-Free: The “M” series features a hard-anodized aluminum housing and a specially treated piston that allows it to run on dry, unlubricated compressed air.

Common Applications

These units are typically used to prevent “bridging” or “rat-holing” in silos and to assist in the flow of bulk materials.

• Feeding and Conveying: Assisting material movement on vibratory tracks or conveyors.

• Emptying Bins/Hoppers: Ensuring powders or small granules don’t stick to the walls.

• Compacting: Removing air from molds or packaging (e.g., settling powder in a bag).

• Screening: Aiding in the separation of different material sizes.
