Sound-insulated fan VENTS Boost-I series

Description

APPLICATION
The inline VENTS Boost-I fans are enclosed in a specially designed sound-insulated casing that ensures silent fan operation in combination with high aerodynamic characteristics. The fans are compatible with round air ducts from Ø 200 up to 250 mm. The VENTS Boost-I fans combine wide capabilities and high performance characteristics of both axial and centrifugal fans, thus providing powerful air flow and high pressure.	The VENTS Boost-I fans are recommended as a component of the air handling systems for various commercial and industrial premises with high requirements to noise level, i.e. libraries, conference halls, educational institutions, kindergartens, etc.
DESIGN
The external casing is made of galvanized steel. Sound and heat insulation is provided by 30 mm acoustic material. Due to the improved mixed type impeller, which is a hybrid of axial and centrifugal impeller, the Boost-I has low power consumption and noise level with high performance.	The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combination of high air flow, increased pressure and low noise. The fan casing is equipped with an airtight terminal box for connection to power mains.

MOTOR
The VENTS Boost-I fans are equipped with single-phase high-efficiency three-speed asynchronous motors with low power consumption. The motor is equipped with thermal switches for overheating protection.	The ball bearings ensure a long service life (about 40 000 hours of continuous operation). The motor ingress protection rating is IPX4.
SPEED CONTROL
The three-speed motor can be controlled using a builtin switch (option V) or an external switch P3-5.0 (purchased separately).
MOUNTING
The fans are designed to be used with round air ducts. The fan casing has mounting brackets for convenient installation onto the ceiling. The ducts can be fitted at any angle relative to the fan axis. Make sure to provide sufficient maintenance access during fan installation.	Electrical connection and installation must be performed in accordance with the instruction manual and the electrical connections diagram applied to the terminal box. A single system may have several fans installed in parallel to boost the output capacity or in series to boost the working pressure.
