B Series Cabinet Air Blower

B series heavy-duty cabinet centrifugal fan is industrial & commercial high static pressure air supply/exhaust equipment, with integrated galvanized sheet frame cabinet, multi-wing high-pressure impeller and optimized volute air duct. Powered by 380V three-phase electricity, it has 10 airflow grades ranging from 2600 to 16000 m³/h, widely used in hospitals, factories, schools, shopping malls and entertainment venues for ventilation, exhaust and pipeline air delivery.

Core Product Features

Structural & Performance Highlights

· Galvanized Sheet Frame Cabinet: Rigid frame structure, double-side maintenance access doors, easy disassembly for internal fan inspection and cleaning; fully sealed cabinet body to avoid air leakage.

· Multi-Wing High-Pressure Centrifugal Impeller: Forward curved multi-blade design, precisely dynamically balanced after assembly, ultra-high static pressure output, large airflow, stable rotation, high efficiency and low running noise.

· Optimized Volute Air Duct Design: Eliminates turbulent airflow loss between impeller and cabinet, maximizes wind pressure and airflow utilization efficiency.

· Ultra-Compact Integrated Body: Small footprint, lightweight structure, supports ceiling concealed hoisting or floor standing installation, flexible layout for various engineering spaces.

· Industrial-grade durable structure, stable 24-hour continuous all-day operation.

Working Principle

Single-way forced air circulation: Driven by multi-wing centrifugal impeller, the fan draws outdoor air into the cabinet and pressurizes it for long-distance duct supply; it can also reversely extract turbid indoor air and exhaust outdoors, applicable for both fresh air supply and waste air exhaust projects.

Typical Application Scenarios

· Medical: Clinics, hospitals, medical wards (rapid exhaust of polluted air)

· Industrial: Production workshops, factory ventilation & exhaust systems

· Public: Schools, shopping malls, catering halls, internet cafes, entertainment venues

· Matching demand: Large closed spaces requiring long pipeline air delivery, venues needing rapid air exchange with poor natural ventilation

Model Selection Case Reference

Take B2K as example: Suitable for a 110㎡ clinic with air change rate of 5 times/hour. One unit quickly discharges indoor turbid air to maintain smooth and comfortable indoor air circulation.

Usage Restrictions

· Power supply: Standard 380V 50Hz three-phase industrial power supply, incompatible with household single-phase 220V sockets, requires dedicated commercial power distribution.

· Installation: Support ceiling hoisting or floor standing; reserve enough maintenance space at the inspection door side.

· Operating ambient temperature: -10℃ ~ 45℃; avoid long-term outdoor direct sunlight exposure.

· Maintenance: Regularly open the maintenance door to clean dust accumulated on the impeller to prevent increased noise and reduced airflow.
