FAQ CATEGORY: FlexPro™ High-Vacuum Series

High-vacuum (hi-vac) extraction systems generate high levels of static pressure to pull dust, fumes, and other particulates through small-diameter hoses or tools. Unlike ambient air filtration or low-vacuum systems, hi-vac units are designed for source capture—removing contaminants as they are produced at the tool tip, weld seam or dust source. This method prevents airborne hazards from spreading throughout the facility.

The key difference between hi-vac and low-vac systems lies in pressure and purpose. Low-vacuum or ambient systems move large volumes of air at low static pressure to clean the air in a room or draw from large hoods. High-vacuum systems operate at much higher static pressure, delivering strong suction through narrow hoses to remove contaminants right at the source. This makes hi-vac ideal for targeted extraction in processes like welding, grinding, sanding and housekeeping.

High-vacuum systems offer several important benefits:

• Effective Source Capture: Removes fumes and dust at the point of generation, preventing exposure and contamination.
• Improved Air Quality: Supports cleaner, healthier work environments and protects worker respiratory health.
• Space Efficiency: Eliminates the need for large overhead hoods or bulky ductwork, preserving valuable workspace.
• Versatility: Compatible with fume guns, extraction tools, robotic cells, and central vacuum systems.
• Energy Efficiency: Targeted extraction uses less air volume, reducing energy costs over time.
• Safety & Compliance: Helps meet OSHA exposure limits, NFPA combustible dust standards, and other safety requirements.

Hi-vac systems are ideal when:

• You need to collect contaminants directly at the point of generation.
• Overhead clearance is limited by cranes, lighting, or other equipment.
• Welding, grinding, sanding, or cutting operations generate dense fumes or fine dust.
• You require a flexible system for both source capture and industrial cleaning.
• You are working with hazardous, combustible, or regulatory-sensitive materials (e.g., stainless steel, pharmaceuticals, battery dust, etc.).

High-vacuum systems can be used with:

• Manual or robotic welding guns with integrated extraction
• Suction nozzles and tubes for grinding and sanding
• Enclosed hoods for small, high-dust operations
• Central vacuum lines for facility cleaning and housekeeping
• Specialized tools in food, pharma, and battery manufacturing for close source capture of fine or hazardous particulate
