Core advantage

1.Compact Structure & Easy Installation

The fan impeller is optimized via ternary fluid simulation, paired with a compact motor design, delivering an ultra-slim profile. Effortless to install, it fits perfectly into the limited space of 2ft/3ft/4ft/5ft/6ft bio-safety cabinets and fully meets rated operating conditions.

2.Precise Control & Stable Airflow

Equipped with an intelligent controller, it supports 0~10V, PWM and RS485 speed control for seamless integration with IoT systems.

When fitted with differential pressure sensors, it enables intelligent airflow compensation and dynamic pressure monitoring, ensuring stable, turbulence-free airflow and extending the service life of the filtration system.

3.Safe Sealing & Full Protection

The fan inlet connects to the pre-filter via a sealed air guide ring, while the outlet integrates with HEPA/ULPA filters. The gap-free air duct design eliminates front-end vortices, ensuring complete sealing and reliable bio-safety protection.

4.Low Operating Cost

Three-in-one high-efficiency design: energy-saving motor, optimized blade profile and precise control, improving overall efficiency, reducing power consumption and long-term operating costs of the cabinet.

5.High Reliability

It has passed a 40,000-hour reliability test at an ambient temperature range of -25℃ to 60℃. It adapts to fluctuations in temperature and humidity, ensuring stable operation, preventing exhaust system failure and eliminating associated bio-safety risks.

6.Eco-Friendly & Low Noise

Low-noise fan impeller with up to G2.5 dynamic balance accuracy and high-precision installation minimizes vibration and excess noise, creating a comfortable operating environment.

FAQ

Q1: Why are EC backward-curved centrifugal fans specially recommended for bio-safety cabinets?

A1: Bio-safety cabinets require high filter resistance resistance and stable negative pressure environment. EC backward-curved centrifugal fans provide sufficient pressure to match HEPA/ULPA filters, maintain stable internal airflow, prevent cross-contamination of bacteria and aerosols, and meet bio-safety laboratory containment standards.

Q2: How does the EC fan ensure stable airflow balance inside the bio-safety cabinet?

A2: The EC brushless motor supports stepless speed regulation and constant air volume output. With optimized impeller aerodynamic design, it maintains consistent inward airflow and downward laminar flow, effectively avoiding turbulence and ensuring the long-term stable operation of the bio-safety cabinet.

Q3: What safety designs does the fan have to adapt to high-standard biomedical environments?

A3: The fan adopts fully sealed structure, anti-leakage air duct design and non-shedding materials. It features low electromagnetic interference, spark-free operation and corrosion-resistant casing, which is easy to disinfect and clean, and complies with bio-safety and GMP hygiene requirements.

Q4: What are the advantages of EC fans in energy consumption and long-term operation for biosafety cabinets?

A4: Compared with traditional AC fans, EC models reduce power consumption significantly. With long service life, low heat generation and maintenance-free bearing design, they greatly lower operating costs and equipment failure rates for 24-hour continuous laboratory operation.

Q5: Can this EC backward-curved centrifugal fan adapt to different levels of bio-safety cabinets?

A5: Yes. It features wide static pressure range and flexible speed adjustment. It is fully compatible with Class II and Class III bio-safety cabinets, can cope with different filter combinations and duct resistance, and meets customized airflow demands for various biomedical protection scenarios.
