● Airflow range: 1150~125143m ³/h
Static pressure range: 225~2900Pa
● Drive form: direct connection
Installation form: seat mounted, lifting
The fifth generation backward tilting centrifugal impeller has high efficiency and does not overload
Precision hyperbolic inlet Venturi tube reduces turbulence and noise
Square volute free structure, small volume, light weight, easy installation
Square design with multiple airflow directions, saving installation costs
● Impeller balance grade G2.5 (AMCA204)
EF-A volute free box type centrifugal fan is suitable for ventilation and fire smoke exhaust in office buildings, hotels, guesthouses, auditoriums, theaters, basements, high-end residential buildings, factories, workshops, shopping malls, hospitals and other places.
When the temperature of the transported gas exceeds 80 ℃, it can be used continuously. When used for fire smoke exhaust, it can operate continuously for no less than 60 minutes at a high temperature of 280C to achieve the purpose of fire smoke exhaust.
Requirements for conveying medium: The medium should be air, non corrosive, non flammable and non explosive. The gas should not contain viscous substances, and the content of dust or hard particles in the gas should not be high
于150mg/m³。
The performance parameters provided in this document are data under standard conditions (i.e., the medium is clean air at standard atmospheric pressure, temperature is equal to 20 ℃, and gas density is equal to 1.2kg/m ³), and its testing method complies with the requirements of the AMCA210 standard for the installation method shown in Figure B (1) (free inlet, pipeline outlet).
The noise is measured as the A-meter sound pressure level, and its data is obtained from a distance of 1 meter from the B (1) type fan when both the inlet and outlet are connected to pipelines. It should be noted that the sound pressure level will change with the characteristics of the testing environment, reflection, and natural frequency. All interpretation rights regarding noise issues belong to our company.
