Excavation Ventilation Blower
Warranty Period :
6 Months
Standing out as a system dedicated to providing fresh air supplies in harsh and confined work environments, the SHENLI CTF-25 Air-Ventilation Fan relies on a copper-wire motor with 350W of power to generate a total static pressure of up to 350 Pa and a rapid airflow rate of 55 m³/min. The unit comes enclosed in a robust 1.5mm thick steel casing and relies on an aerodynamically engineered multi-blade aluminum alloy impeller with a diameter of 250mm (10-inch) to deliver massive airflow without exposing the blades to any deformation, even at peak operating speeds of 3450 RPM.
This Excavation Ventilation Blower is built to withstand the toughest job site conditions, featuring IP55-rated protection against dust and water splashes, alongside rims designed to easily secure and fasten flexible ventilation hoses. Operating at a controlled noise level of 66 dB, the machine enhances occupational safety standards in confined spaces by pumping fresh air into manholes, sewers, and deep storage tanks, ensuring continuous performance every single day.
• 100% Pure Copper Motor: Premium copper-wire windings prevent overheating, ensuring extended continuous-duty runtime and optimal energy efficiency.
• Aluminum Alloy Impeller: Aerodynamically engineered die-cast metal blades deliver large-volume airflow and reliable suction without high-speed deformation.
• Heavy-Duty Steel Construction: A robust 1.5mm thick steel casing and secure protective mesh grilles confidently withstand high-impact industrial abuse.
• IP55 Weather & Dust Protection: Superior resilience against heavy dust ingress and low-pressure water splashes ensures safe operation in harsh outdoor environments.
• High-Static Pressure Output: Generates up to 350 Pa of pressure to efficiently push or pull air through long distances of attached flexible ducting.
• High-Speed Dual Frequency: Dynamically handles 50/60Hz frequencies, spinning up to 3450 RPM to clear out stagnant air volumes rapidly.
• Flared Duct Rims: Flared intake and exhaust rims allow operators to easily clamp down standard 10-inch telescopic flexible ducting hoses.
• Managed Noise Levels: Operates at a contained acoustic rating of 66 dB(A) to keep high-velocity workplace noise within manageable, safe limits.
• Multi-Industry Application: Optimally designed to support factories, large workshops, commercial warehouses, basements, shipyards, chemical labs, and tunnels.
• Confined Space Occupational Safety: Enhances workspace regulations by delivering fresh oxygen and clearing stale air from manholes, sewers, and deep storage tanks.
• Dual Blower & Exhaust Functionality: Configures dynamically as a positive-pressure fresh air blower or a heavy suction exhaust fan for precise directional airflow.
• Optimized Portability & Grip: A compact design paired with a balanced carrying handle and rubberized anti-vibration feet ensures quick setup and high mobility across active jobsites.
