Excavation Ventilation Blower
Warranty Period :
6 Months
The SHENLI CTF-20 is an Excavation Ventilation Blower strictly built to execute high-capacity extraction within tightly confined environments. Powered by an efficient 230W copper-wire motor, the mechanics rely on a highly balanced 200mm (8-inch) multi-blade aluminum alloy impeller. Housed inside a rugged 1.5mm thick steel casing, this configuration generates a maximum total static pressure of 295 Pa alongside a rapid fluid displacement rate of 30 m³/min. Hitting peak rotational speeds of 3450 RPM, the internal components effortlessly process heavy air volumes without bending or succumbing to extreme suction forces.
Featuring a highly durable design, this unit serves for heavy-duty tasks such as smoke clearing, dust extraction, and active jobsite ventilation. It can be instantly configured to operate as either a positive-pressure fresh air blower or a powerful exhaust fan. To ensure continuous operation in harsh environmental conditions, the machine is equipped with IP55 dust and water protection, vibration-absorbing rubber feet, and specialized rims designed to securely clamp 8-inch flexible ventilation hoses..
• Thermal-Resistant Copper Core: Premium pure wire windings actively mitigate thermal buildup, ensuring exceptional energy utilization and prolonged operational cycles without the risk of sudden motor shutdowns.
• Die-Cast Aerodynamic Blades: The precision-crafted metal impeller maintains absolute structural integrity under extreme velocities, rapidly displacing heavy air columns without warping or fracturing.
• Reinforced Steel Housing: A heavy-gauge 1.5mm metal enclosure protected by dense front and back mesh grilles defends the internal mechanics from abrasive industrial impacts and accidental drops.
• IP55 Protection: Fully certified against severe dust accumulation and water sprays, rendering the machine perfectly viable for harsh outdoor operations and challenging construction sites.
• 295 Pa Pressure: Forcefully channels high-velocity airflow through extended lengths of attached flexible ductwork, effectively eliminating resistance while maintaining uncompromising suction.
• 3450 RPM Rotational Output: Seamlessly adapts to 50/60Hz grids, utilizing aggressive spinning speeds to purge up to 30 cubic meters of contaminated, stagnant air every single minute.
• Anti-Vibration Base Layout: Integrates thick shock-absorbing rubber feet to prevent hazardous floor drifting while the balanced top-mounted handle allows for effortless jobsite relocation.
• Telescopic Hose Compatibility: Carefully molded intake and exhaust collars guarantee a tight, fail-safe fit for clamping down all standard 8-inch flexible ventilation tubing.
• Managed Noise Levels: Keeps high-velocity workplace acoustics within manageable limits by operating at a contained acoustic rating of 61 dB(A).
• Bidirectional Air Management: Seamlessly switches functions between injecting clean, breathable environmental air and aggressively extracting heavy industrial exhaust or hazardous fumes.
• Compact 10 Kg Architecture: The remarkably lightweight yet highly rugged build facilitates immediate, rapid-response deployment across shifting and unpredictable work zones.
