Vacuum Blower for Abrasive Recovery

Product Name: SSR250VH High-Vacuum Roots Blower for Marine Abrasive Blasting & Suction Systems

Outlet diameter: 250A, flow rate: 65m³/min at -60kPa, no water cooling system required

This Roots blower is a highly efficient core power unit designed specifically for marine abrasive blasting and suction systems. It features a classic twin-rotor, three-lobed profile, ensuring smooth operation, low pulsation, and low noise. Specially treated with corrosion protection and a surface spray coating, the blower effectively withstands the high salinity and humidity of the marine environment, ensuring long-term durability. Its most notable feature is its ability to provide continuous, stable, and powerful vacuum suction, maintaining a constant flow rate even under high abrasive and dust loads, resulting in extremely high recovery efficiency. Furthermore, its compact design and simple maintenance make it easy to install and perform routine maintenance on limited ship decks.

This blower is primarily used to power vacuum recovery sandblasting and rust removal systems in the shipbuilding industry. It provides the core power for the entire system, generating high-intensity negative pressure at the recovery gun tip to instantly recycle waste abrasive (such as steel shot and grit), iron oxide scale, and harmful dust produced after sandblasting, thereby achieving abrasive recycling and maintaining a clean and environmentally friendly work site. Its exceptional reliability completely eliminates the environmental pollution and material waste associated with traditional sandblasting and rust removal.

It is widely used for efficient and environmentally friendly rust removal and maintenance operations on hulls, decks, ballast tanks, and docks, making it a key piece of equipment for modern green ship repair. Experts at the China Shipbuilding Industry Research Institute have certified this product as meeting the performance of imported Roots vacuum pumps used in sand suction machines for shipbuilding and coating applications. It can fully replace imported pumps, delivering the same effectiveness as mobile and fixed systems while simultaneously reducing costs and increasing efficiency. It is currently in widespread use at major Chinese shipyards.
