Negative Pressure Vacuum Tank Vacuum Equipment: Advanced Pressure Stabilization System
Product Description: The negative pressure vacuum tank is widely used in production of all kinds of paper pulp trays. As an indispensable auxiliary equipment for Molded Pulp Forming Machine and Molded Pulp Shaping Machine in paper tray production lines, this system provides critical vacuum support for consistent, high-quality molded pulp manufacturing.
Enhanced Features & Advantages:
✔ High-Capacity Pressure Stabilization - Maintains vacuum levels within ±1% fluctuation ✔ Industrial-Grade Construction - 304/316L stainless steel with reinforced structural design ✔ Intelligent Pressure Management - Auto-compensation for instantaneous demand changes ✔ Energy Efficient Operation - Reduces vacuum pump cycling by 40% ✔ Multi-Stage Filtration - Integrated moisture and particulate separation
Technical Specifications:
Capacity Range: 0.5-10m³ (custom sizes available)
Working Pressure: -0.08MPa to -0.095MPa (adjustable)
Material Thickness: 3-12mm (pressure-optimized)
Connection Ports: DN50-DN200 standard flanges
Protection Class: IP65 (outdoor models available)
Core Functionality: Designed specifically for paper tray production, its primary function is negative pressure storage. By connecting to vacuum pumps, it establishes and maintains stable negative pressure conditions, then efficiently distributes this vacuum resource to both forming machines and shaping machines throughout the production line. This ensures uninterrupted operation and consistent product quality.
