Products Description
Need a manual, dust-free way to transfer powders from bags or drums into your vacuum conveying system?
Guanjiang's Vacuum Conveying Equipment Suction Gun is the core component of manual powder conveying systems — enabling precise material extraction and transfer through vacuum negative pressure principles. This handheld device is constructed from stainless steel or FDA-compliant polymer materials, featuring an ergonomic lightweight handle and precisely controlled air intake valves. Simply insert directly into raw material packaging for efficient, clean, dust-free material transfer. Ideal for pharmaceutical, food, and chemical small-batch charging applications.
Key Advantages
Lightweight design enables single-handed operation. Adapts flexibly to various packaging containers and charging ports. Plug-and-play quick connection to conveying systems.
Fully enclosed transfer eliminates dust leakage. Food-grade materials prevent product contamination. Easy-disassembly structure facilitates thorough cleaning.
Rapid material extraction reduces processing time. Minimal residual design decreases material waste. Intuitive operation requires minimal training.
Anti-static options prevent spark generation in explosive environments. Ergonomic design reduces operator fatigue. Safety lock mechanisms prevent accidental operation.
Lower initial investment compared to automated systems. Reduced cleaning and maintenance costs.
Tool-free disassembly for thorough cleaning — ideal for frequent product changeovers.
Suitable for small-batch and multi-variety production — flexible and economical.
How It Works
The suction gun connects to the vacuum conveying system via quick-disconnect couplings, generating a controlled negative pressure zone at the nozzle. Its internal structure employs Venturi principles or vacuum generation devices, complemented by anti-backflow designs to ensure leak-free and splash-free material transfer.
Operation: Simply insert the nozzle into raw material packaging (bags, drums, or small containers). The vacuum system automatically extracts powder through the gun into the conveying line — dust-free, efficient, and operator-safe.

Frequently Asked Questions
Q1: How does the suction gun prevent dust from escaping?
A: The suction gun connects to the vacuum conveying system, creating a controlled negative pressure zone at the nozzle. Any dust generated during material pickup is immediately drawn into the vacuum line — not into the operator's breathing zone. This creates a fully enclosed transfer from container to conveying system.
Q2: Can the suction gun be used with sticky or cohesive powders?
A: Yes. For sticky or cohesive powders, we recommend our PTFE-coated stainless steel version or a flared tip nozzle. The non-stick coating prevents material build-up inside the gun. An adjustable air intake valve also helps regulate suction force to prevent clogging.
Q3: Is the suction gun suitable for explosive environments?
A: For explosive environments (combustible dusts), we offer an anti-static version with grounding wire connection. This dissipates static charge buildup during powder transfer — preventing spark generation. Please specify ATEX requirements when ordering.
Q4: How do you clean the suction gun between different products?
A: The suction gun features an easy-disassembly structure — no tools required. Simply disconnect from the vacuum line, disassemble the body, and clean all internal surfaces. Stainless steel versions can be autoclaved or cleaned with solvents. Polymer versions are dishwasher safe. This makes it ideal for frequent product changeovers.
Q5: What sizes and nozzle types are available?
A: Standard lengths: 300mm, 500mm, 700mm, 1000mm. Nozzle diameters: 20mm to 50mm. Tip styles: straight tip (general purpose), angled tip (for bag corners), flared tip (for sticky materials), and flexible extension (for reaching into drums). Custom sizes available upon request.
