The inlet cone is recommended to be installed upstream of the fan to improve the air flow parameters. However, it must be installed in the absence of ducting attached to the fan inlet. The inlet cone helps reduce the fan dynamic pressure and increase the static component of the total fan pressure. The unit can be used in combination with the SZ-VPVO protective mesh which must be one size larger than the unit.
The unit has two flanges and is made of steel with a polymer coating.
