Product Overview

The Helix-45M Compact Screw Blower is a high-efficiency, space-saving pneumatic solution engineered for demanding industrial environments. As a premium-tier compact screw blower, it delivers reliable continuous airflow at 4200 m³/h and up to 0.8 bar pressure — ideal for applications requiring stable, oil-free compressed air without the footprint of traditional centrifugal or lobe blowers. Its integrated variable frequency drive (VFD) enables precise speed control, energy optimization, and soft-start functionality — making it a leading VFD screw blower for smart manufacturing systems. Certified to CE and ATEX Zone 2 standards, this ATEX blower is approved for use in potentially explosive atmospheres where flammable gases or vapors may be present, ensuring full compliance with EU safety directives.

Designed for rugged 24/7 operation, the Helix-45M leverages advanced asymmetric twin-screw rotor geometry, precision-machined aluminum alloy housing, and intelligent thermal management to maximize uptime and minimize lifecycle costs. Its modular architecture supports seamless integration into existing process lines, SCADA networks, and Industry 4.0 platforms.

Key Features

• Integrated VFD for dynamic flow/pressure control and up to 35% energy savings vs. fixed-speed equivalents
• ATEX Zone 2 certification (EN ISO 80079-34 & EN 60079-0) for safe operation in hazardous areas
• Compact footprint — 30% smaller than comparable 45kW blowers, enabling retrofit in constrained spaces
• Oil-free, pulse-free airflow with <1.5% pressure fluctuation for sensitive processes
• Intelligent onboard controller with Modbus RTU/ASCII, analog I/O, and real-time diagnostics
• Low-noise enclosure (<72 dB(A) @ 1m) with vibration-damped mounting system

Technical Specifications

Applications

The Helix-45M is widely deployed across wastewater treatment plants, chemical dosing systems, pneumatic conveying lines, biogas upgrading facilities, and food-grade vacuum packaging — wherever a certified 45kW blower must operate safely, efficiently, and quietly in regulated or hazardous zones. Its compact design and Helix-45M platform scalability make it especially suited for modular plant expansions, OEM equipment integration, and retrofits replacing aging lobe or turbo blowers.
