Venturi ejector for heavy-duty applications Model 150200

for bulk materialsfor conveyorfor pneumatic conveying

Overview
The Heavy Duty Line Vac™ is EXAIR's largest-capacity Line Vac designed for conveying abrasive or heavy materials and for transfer over extended vertical and horizontal distances. It resembles the standard Line Vac but uses a hardened alloy construction to reduce wear compared with aluminum or standard stainless steel. Available in hose I.D. sizes from 3/4″ (19 mm) through 3″ (76 mm).

Applications

• Hopper loading
• Fiber tensioning
• Material conveying
• Waste and trim removal
• Chip removal
• Part transfer
• Filling operations

Advantages

• Hardened alloy construction for improved wear resistance
• High throughput capacity
• Compact footprint
• Low noise
• No moving parts
• Compatible with standard hose, tube and pipe
• Available from stock

Models
Heavy Duty Line Vacs are offered individually and in NPT-threaded kits. Kits include a Heavy Duty Line Vac, filter separator and pressure regulator with coupler. Seven sizes up to 3″ (76 mm) are available; threaded and flanged variants are also offered.

How it works
Compressed air enters an annular plenum and is injected into the throat through directed nozzles. The resulting air jets create a vacuum at the intake, drawing material into the unit and accelerating it through the outlet for conveying over long vertical or horizontal distances.
