Product Description

High-Efficiency Industrial Roots Blowers

Engineered for reliable performance in demanding industrial environments, our Roots Blowers deliver consistent airflow and pressure for applications ranging from wastewater treatment to pneumatic conveying. Built with robust cast iron or lightweight aluminum alloy housings, these positive displacement blowers feature precision-machined lobes for minimal air leakage and energy-efficient operation.

Key Features:

• Durable Construction: Corrosion-resistant materials and heat-treated gears ensure long service life in harsh conditions.
• Low Noise & Vibration: Advanced rotor balancing and sound-insulated enclosures reduce operational noise by 30%.
• Variable Frequency Compatibility: Pair with VFDs for adjustable airflow, cutting energy costs by up to 40%.
• Multi-Application Design: Available in oil-free (food-grade hygiene) or explosion-proof (ATEX-certified) models for diverse industries.

Technical Specs:

• Airflow: 5-500 m³/min
• Pressure: 10-100 kPa (positive) / -30 kPa (vacuum)
• Motor: IE3,IP55 protection
• Materials: Cast iron, aluminum alloy, or stainless steel (customizable).

 

Ideal for wastewater aeration, grain conveying, aquaculture, and chemical processing, our blowers combine rugged durability with intelligent design for minimal maintenance and maximum uptime. Trusted by global industrial clients, we offer tailored solutions to meet your specific pressure and airflow requirements.

Product Parameters

 

Category	Details
Model	Standard series with airflow ranging from 5-500 m³/min; custom models available for special applications (explosion-proof, oil-free, high-temperature).
Type	Positive displacement blower with twin-lobe or tri-lobe rotors (tri-lobe for quieter operation).
Structure	Horizontal/vertical configuration; single-stage/double-stage design (for higher pressure).
Performance	- Airflow: 5-500 m³/min (dependent on model) - Pressure Range: Positive: 10-100 kPa; Vacuum: -10 to -30 kPa - Speed: 600-3,000 RPM (adjustable via VFD) - Noise Level: 75-90 dB (with soundproof enclosure option, ≤70 dB) - Efficiency: Up to 90% energy conversion (IE3 motor standard).
Motor	- Type: IE3/IE4 high-efficiency asynchronous motor - Voltage: 380V/50Hz (customizable for 220V, 440V, 60Hz) - Power: 0.75-200 kW - Protection: IP55 (dust/waterproof); IP66 for harsh environments - Cooling: Air-cooled (optional water-cooled for high-temperature use).
Materials	- Housing: Cast iron (standard), aluminum alloy (lightweight), stainless steel 304/316 (corrosion-resistant) - Impellers: Carbon steel (heat-treated), stainless steel, or epoxy-coated for anti-corrosion - Gears: Helical gears (steel alloy, precision ground for low backlash) - Seals: Mechanical seals (oil-free models) or lip seals (oil-lubricated models).
Lubrication	- Oil-lubricated (standard, for industrial use): Gearbox with synthetic oil (replace every 5,000 hours) - Oil-free (hygienic): Fully sealed gearbox, the impellers operate without oil contact (ideal for food/pharma).
Certifications	CE, ISO9001
Installation	- Mounting: Floor-mounted (with anti-vibration pads) or skid-mounted (for mobile systems) - Inlet/Outlet: Flanged connection (ANSI/DIN standards), DN50-DN300. - Required Clearance: 1m around the blower for maintenance access.
