4 kW 318 m³/h Blower Vacuum Pump Motor

This 4 KW 318 m³/h Blower Vacuum Pump Motor is a high-performance side channel blower unit used in industrial automation systems, particularly for workpiece fixation on the vacuum tables of CNC Router machines. With a nominal motor power of 4.0 kW (5.5 HP), this system offers a significant air intake flow rate capacity of 318 cubic meters per hour (m³). Its operating principle involves drawing atmospheric air through an inlet port, creating centrifugal force via a specially designed side channel and a multi-blade impeller, and discharging this air in a spiral trajectory at high speed through the outlet port. This “Vortex” effect generates a continuous and high-volume airflow, creating a pressure difference between the vacuum table and the material being processed. It ensures that the workpiece is held firmly and stably onto the table surface, even with porous materials like MDF, Particleboard, Plexiglass, and Composites, by continuously exhausting air leaking from the material’s surface. This mechanism prevents slippage during processing, increasing precision and eliminating the time and labor costs associated with traditional mechanical clamping methods.

The product’s structural design is based on industrial durability and a maintenance-free, long-lasting operating principle. The cast body structure enhances mechanical strength and vibration damping, while its internal mechanism, unlike oil-lubricated vane vacuum pumps, has no moving parts subject to friction or wear. This “Maintenance-Free Technology” eliminates periodic maintenance needs such as oil changes or vane replacements and prevents oil vapor emissions from the exhaust. Its electrical supply is 3 Phase 380V AC (Three-Phase), designed to provide stable and continuous power even under heavy industrial loads. The inlet/outlet ports feature standard 2″ threaded connections, allowing for easy integration into existing industrial setups. While primarily optimized for CNC vacuum tables of dimensions 130×250 cm or 150×300 cm, this blower can also be used with larger tables (e.g., 210×280 cm) through parallel connection configurations. Furthermore, its high flow rate capacity and maintenance-free nature make it a reliable solution in various applications such as pneumatic conveying, ventilation, drying ovens, and general industrial vacuum/pressurized air applications.

Superior Workpiece Fixation with High Airflow: The blower’s high air intake flow rate of 318 m³/h provides a critical advantage in securing workpieces on CNC vacuum tables, especially for porous materials or those prone to air leakage, such as MDF, Particleboard, and Plexiglass. Unlike conventional vacuum pumps, this high flow rate continuously and effectively exhausts atmospheric air leaking through micro-gaps between the workpiece and the table, guaranteeing the maintenance of sufficient and stable negative pressure difference on the table surface. This ensures maximum resistance against processing forces, minimizes the risk of workpiece slippage, and significantly enhances the geometric precision and surface quality of the final product. This dynamic airflow capacity, rather than static vacuum pressure, is the decisive factor for processing stability in real-world industrial applications.

Maintenance-Free Technology and Optimized Total Cost of Ownership (TCO): A fundamental characteristic of side channel blower technology is the absence of physical contact between the rotating impeller and the stationary housing. This design completely eliminates friction and wear, negating the need for lubrication and the replacement of consumables like vanes. Consequently, this blower requires no routine and costly maintenance operations such as oil changes, filter replacements (excluding external vacuum filters), or renewal of worn vanes. This minimizes operational downtime, reduces labor costs, and eliminates consumable expenses, significantly lowering the Total Cost of Ownership (TCO).
