Products Description
Need a safe, explosion-proof vibration solution for material flow in hoppers or silos?
Guanjiang's Pneumatic Turbine Vibrator uses compressed air to drive a rotating turbine — converting pneumatic energy into high-frequency, low-amplitude vibrations. With no electrical components, it offers spark-free, explosion-proof operation for hazardous environments. Delivering 2,000 to 18,000 RPM with variable force outputs, it's ideal for dislodging stuck materials in hoppers, chutes, and silos across food, pharmaceutical, chemical, and mining industries.
Key Advantages
No electrical components — zero spark risk. Cool operation prevents burn hazards. Ideal for hazardous environments with combustible dust or gases.
Minimal moving parts reduce failure points. Self-cleaning design resists contamination. Continuous operation capability for demanding industrial environments.
Typically 1-25 CFM air consumption. Minimal maintenance requirements. Long service life with proper air filtration.
2,000-18,000 RPM adjustable range. Instant start/stop capability. Multiple mounting configurations for versatile installation.
Oil-free operation available — prevents product contamination. Suitable for food and pharmaceutical applications.
Available with integrated mufflers for reduced noise levels — meets workplace safety standards.
Aluminum / Stainless steel (corrosion-resistant) / Cast iron (heavy-duty) housings available.

? Selection & Installation Guide:
Application guidelines: For fine powders in small hoppers → higher frequency (10,000+ RPM). For heavy granular materials in large silos → higher force (2,000+ N).
Mounting options: Flange mount / Bracket mount / Cradle mount / Custom adapter plates
Air quality recommendation: Use filtered, lubricated (or oil-free) compressed air. For oil-free applications, specify oil-less turbine models.

Frequently Asked Questions
Q1: How does the pneumatic turbine vibrator work?
A: Compressed air propels turbine blades, creating rotational force. This force is transformed into high-frequency, low-amplitude vibrations through an eccentric weight system. The result is controlled, adjustable vibration without any electrical components — inherently explosion-proof.
Q2: Why choose a pneumatic vibrator over an electric vibrator?
A: Pneumatic vibrators are explosion-proof by design (no sparks), run cooler, offer infinitely adjustable frequency by varying air pressure, and are lighter than electric motors of equivalent force. They excel in hazardous, high-temperature, or wet environments where electric vibrators pose safety risks.
Q3: Can the vibrator be used in food or pharmaceutical applications?
A: Yes. We offer stainless steel (SS304/316L) housings with oil-free operation options. The smooth, polished surfaces prevent product accumulation, and the oil-free design eliminates contamination risk — suitable for GMP-compliant food and pharmaceutical processing.
Q4: How do I select the right vibrator size for my hopper?
A: Selection depends on hopper wall thickness, material type, and flow problem. As a general guide: small hoppers (1-3 m³) → 50-500 N force; medium hoppers (3-10 m³) → 500-2,000 N; large silos (>10 m³) → 2,000-5,000 N. Contact us with your specific parameters for a recommendation.
Q5: Does the vibrator require lubrication?
A: Standard models require oil-mist lubrication for extended life. However, we offer oil-free turbine models for applications where oil contamination is unacceptable (food, pharmaceutical, cleanroom). Specify your requirement when ordering.
