NTP / FP-M Series Piston Pneumatic Vibrator

SOLH NTP / FP-M Series Piston Pneumatic Vibrator (Reciprocating Impact Type)

Brand: SOLH by Richge Technology | Linear Reciprocating Piston Air Knocker, Not Rotary Centrifugal Type

1. Working Principle & Common Features

   This is a linear reciprocating impact vibrator (not centrifugal rotary type). Compressed air drives the piston to strike at high speed back and forth inside the cylinder, generating strong linear impact force. Widely used for silo anti-blocking, vibrating tables, material screening and conveying.

     • Working Principle: Differential air pressure drives the piston to reciprocate and impact at high frequency inside the cylinder to produce linear vibration force.

     • General Advantages
     ✅ High impact force, stronger output than ball / turbine vibrators of the same size
     ✅ Low noise level: 60–75 dB, quieter than K / GT rotary vibrators
     ✅ Adjustable performance: frequency and amplitude controlled by air pressure from 0.2–0.6 MPa
     ✅ High temperature resistance: standard version up to 150℃, custom version up to 200℃
     ✅ Explosion-proof, dustproof and moisture-proof, suitable for powder, chemical, food and humid environments
     ✅ Low lubrication requirement, long service life

4. Selection Guide: FP-M VS NTP

5. Core Difference VS K / GT Rotary Vibrators

     • K / GT (Centrifugal Rotary): High frequency, small amplitude, circular vibration. Suitable for material flow assistance, light compaction and fine powder.

     • NTP / FP-M (Reciprocating Piston Impact): Low frequency, large amplitude, strong linear impact. Suitable for severe bridging blocking, heavy load, thick-wall silos and vibrating tables.
