SIAV/H Series High-Vacuum Air Injected Blowers from 3577 CFM - 6600 CFM

The SIAV/H series are tailored for high vacuum, heavy duty applications in the septic and municipal waste industries. They excel in handling corrosive, abrasive and sensitive materials offering superior performance with minimal maintenance. The SIAV series is designed for the oil and gas industry while the SIAH series is perfect for high vacuum applications in hazardous waste recovery and hydro excavation.

  • High vacuum capability of up to 28" of HG, perfect for efficient suction in challenging environments
  • Air-cooled and fluid-free design, eliminating the need for water or oil recovery
  • Self protecting under closed inlet conditions, ensuring reliability
  • Compact and lightweight, offering the best weight to capacity ratio in its class
  • Easy installation and maintenance, reducing total cost of ownership
  • Flexible drive options (V-Belt, hydraulic, diesel, electric or PTO)

Better by Design

Engineered for efficient, reliable vacuum performance, this blower features a three‑lobe impeller construction paired with a unique air injection system to improve efficiency and reduce operating noise compared to traditional two‑lobe designs. A high‑performance sealing arrangement using three piston rings supports high‑vacuum operation, including dead‑end conditions, without overheating. The design delivers 100% oil‑free air with no oil or water cooling required, while using less horsepower to achieve the same performance and maintaining cooler operating temperatures. Available in eight configurations: BS CW, LH CW, TS CW, RH CW, BS CCW, LH CCW, TS CCW, and RH CCW, it offers the flexibility to meet a wide range of system and installation requirements.

  • The only vacuum pump that can operate safely with the inlet blocked, thanks to advanced air injection technology, ensuring continuous operations even under extreme conditions.
  • Ideal for high-vacuum applications in hazardous waste recovery and septic systems
  • Runs without fluid, ensuring environmentally friendly operation with dry exhaust air
  • Can operate safely even with a closed inlet, thanks to its advanced air injection technology
  • Sewer cleaning and sludge recovery as these blowers are optimized for high vacuum applications in septic and municipal waste systems
  • Sewer treatment and industrial cleaning, as these pumps are designed for handling corrosive and abrasive materials
  • Mobile waste handling units for industrial and municipal use, especially in hazardous environments
