Products Description
Need a maintenance-free vacuum conveyor for medium to large production lines?
Guanjiang's QVC-4 Vacuum Powder Conveyor uses a compressed air-driven vacuum generator (no mechanical vacuum pump) to create negative pressure — offering a simple, compact, maintenance-free solution with 600-3000 kg/h capacity and a 42L bin volume. With a φ420×1361mm footprint, it's ideal for tablet presses, capsule filling machines, dry granulators, packaging machines, and vibrating screens in medium to large-scale production. Features automatic pulse back-blow filter cleaning, GMP compliance, and elimination of material static electricity.
Key Advantages of QVC-4
Delivers 600-3000 kg/h throughput with a 42L bin volume. Ideal for medium to large-scale pharmaceutical and food production lines.
Uses compressed air-driven vacuum generator — maintenance-free, no moving parts, low noise. Simple structure with easy control.
High vacuum prevents material stratification — ensures uniformity of mixed material components for consistent product quality.
Complies with GMP requirements and eliminates material static electricity. Fully enclosed dust-free operation for clean production.
Additional Features
✅ Automatic pulse back-blow filter cleaning — no manual intervention
✅ Low noise operation — ideal for production environments
✅ Automatic level control — start/stop based on hopper fill level
✅ Simple, easy-to-clean design — quick disassembly for batch changeovers
How It Works
- Vacuum Generation: Compressed air supplied to the vacuum generator creates negative pressure, forming a vacuum airflow.
- Material Suction: Materials are sucked into the suction nozzle, forming a solid-gas flow that travels to the hopper.
- Filtration: The filter completely separates materials from air — clean air exhausts, materials collect in hopper.
- Discharge: When hopper is full, controller automatically cuts off air supply. Hopper door opens, materials fall into equipment hopper.
- Filter Cleaning: Compressed air automatically cleans the filter through the pulse back-blow valve.
- Auto-Restart: When set time is reached or level sensor sends feeding signal, feeder automatically restarts.

? Which Model Should You Choose?
QVC-4 (42L, 600-3000 kg/h): Ideal for medium to large-scale production lines. The 42L bin volume provides good buffer capacity, reducing refill frequency while maintaining a reasonable footprint.
For higher capacity: QVC-5 (60L, 900-6000 kg/h) — see table above.
For smaller applications: QVC-1/2/3 for lab and small-batch production.
Vacuum Conveyor FAQs
Q1: What is the difference between QVC-4 and ZKS series?
A: QVC series uses a compressed air-driven vacuum generator — no mechanical vacuum pump, simpler structure, maintenance-free, lower noise. ZKS series uses an electric vacuum pump — suitable for even higher continuous capacities. QVC-4 offers an excellent balance of capacity (600-3000 kg/h) and maintenance-free operation for medium to large production lines.
Q2: What is the gas consumption of QVC-4?
A: QVC-4 consumes 1440 NL/min of compressed air at 0.4-0.6 MPa. Ensure your facility's compressed air system can supply this volume. For comparison, QVC-3 consumes 720 NL/min, and QVC-5 consumes 2880 NL/min.
Q3: Is QVC-4 suitable for tablet press feeding in large-scale production?
A: Yes. The QVC-4 is specifically designed for automatic feeding of tablet presses, capsule filling machines, dry granulators, packaging machines, crushers, and vibrating screens in medium to large-scale production. Its 42L bin volume provides sufficient buffer for high-speed tablet presses.
Q4: Does the QVC-4 require a separate vacuum pump?
A: No. Like all QVC series models, the QVC-4 uses a built-in vacuum generator powered by compressed air (0.4-0.6 MPa). No mechanical vacuum pump needed — no moving parts, no oil, no maintenance, and very low noise.
Q5: How is the QVC-4 cleaned between batches?
A: The QVC-4 features a simple, easy-to-clean design with quick-release clamps for disassembly. The 42L bin volume is manageable for manual cleaning. All contact parts can be easily accessed. For automated cleaning, CIP options are available for pharmaceutical applications.
