High-pressure fans

Product catalog summary
Overview
Venti specializes in manufacturing high-pressure fans for industrial applications, offering models with both direct and indirect motor drives. These fans are recognized for their compact and robust construction, maintaining constant pressure across various flow volumes.
Specifications
  • Type HV-M: Direct motor drive, pressure range 30 to 125 mbar.
  • Type HV-K: Indirect motor drive via shaft and coupling, pressure range 30 to 160 mbar.
  • Type HV-ZM: Two-stage fan combination with direct motor drive, pressure range 200 to 250 mbar.
Construction and Features
The fans feature a strong, welded design with a rotatable fan scroll for flexible positioning. Impellers are made from materials like welded steel, aluminium, and cast silumin, balanced to minimize noise. Options include v-belt drives, heat- and acid-proof materials, explosion protection, and gas-tight versions.
Applications
These fans are used in industrial processing, chemical engineering, fluidization of powders, and as forced-draft fans in industries such as cement, paint, and plastics.
Performance and Dimensions
Detailed tables provide performance metrics, including flow volume, motor output, sound pressure levels, and dimensions for pressure ranges from 30 mbar to 160 mbar. The fans are designed for efficient operation with low energy consumption and noise levels.
Accessories and Customization
Customization options include throttle valves, silencers, acoustic enclosures, inlet filters, and vibration dampers. Flexible joints for inlet and outlet connections are available in materials like neoprene, silicon glass, or PVC polyester.
Noise Reduction
Acoustic enclosures are recommended to meet legal noise reduction requirements and improve working conditions by effectively absorbing sound energy.
Acoustic Enclosures and Splitter Silencers
These enclosures, combined with splitter silencers, effectively reduce sound pressure levels. They include access openings for maintenance and are constructed with insulating walls. Additional ventilation may be required for more powerful motors.
Specifications and Customization
Customized splitter silencers are available to meet specific requirements, ensuring minimal pressure reduction. Simple casing insulation is offered for less demanding noise insulation needs.
Performance and Design
The acoustic enclosure's insertion attenuation value is detailed according to VDI 2711 standards, with a graph illustrating insulation values across various frequencies. The design includes a perforated plate, abrasion-proof mineral fiber plate, anti-drone lining, and loose mineral fiber.
Applications
These solutions are applicable in exhaust air treatment plants, dust collection, process air cleaning plants, ventilating, heating, air conditioning plants, industrial fans, surface technology, and recycling and waste processing plants.
