SHENLI Air-Ventilation Fan, 2400W, 700mm (28-Inch) - CTF70

Ventilation Blower (28-Inch)

The SHENLI CTF-70 ventilation fan operates as a primary system for air management in large commercial facilities. The machine utilizes a 2400W copper motor reaching a rotational speed of 1720 RPM, generating a total pressure of 650 Pa. This design allows achieving an airflow rate of up to 330 m³/min, ensuring continuous air exchange inside workshops and warehouses.

The equipment is protected from harsh site conditions through an IP55 rating and a steel chassis with a thickness ranging between 1.5 and 1.8 mm, maintaining its mechanical integrity under continuous operation. To ensure practical deployment of the equipment despite its large size, the main chassis is equipped with heavy-duty bottom casters. This allows site operators to easily roll the unit across flat surfaces and configure it either for exhaust extraction or air supply.

Key Features & Benefits:

• 2400W Copper Motor: Integrates premium copper-wire windings explicitly engineered to sustain continuous, high-efficiency operations while effectively resisting thermal overload during extended daily run times.

• Aerodynamic Aluminum Impeller: Features dynamically balanced aluminum alloy blades configured to maximize aerodynamic suction, ensuring the rigid structure delivers ultra-large airflow without warping under high-speed stress.

• Reinforced Steel Architecture: The main body is constructed using an extra-rugged 1.5mm to 1.8mm thick metal housing to reliably withstand harsh industrial impacts and daily mechanical wear across active jobsites.

• IP55 Environmental Shielding: Carries a certified protection rating that securely seals the internal mechanics, preventing heavy dust accumulation and blocking intrusive water sprays in unpredictable environments.

• Bidirectional Air Management: The versatile system adapts instantly to site requirements, functioning reliably as either a positive-pressure fresh air blower or a dedicated contaminated air exhaust fan.

• 1720 RPM Rotational Velocity: Relies on optimized spinning speeds to provide rapid air clearing, instantly breaking up and removing large concentrations of stagnant, contaminated air from commercial spaces.

• 330 m³/min Airflow Capacity: Engineered to move an exceptional 330 cubic meters of air every minute, allowing the immediate clearance of smoke, fumes, and intense heat from large industrial zones.

• 650 Pa Static Pressure: Generates substantial internal force to move heavy air columns, enabling the equipment to efficiently push or pull air through extended lengths of attached flexible ducting without a significant performance drop.

• Integrated Heavy-Duty Mobility: Practical maneuverability is engineered directly into the heavy chassis through the inclusion of heavy-duty bottom casters, enabling effortless, one-person movement and positioning across facility floors.
