FKD 16 XL Mixed Flow Fan

Item Number: 40022

• Mixed-flow impeller

• 100% Speed-controllable

• Integral thermal contacts

• Air stream temperatures up to 140 °F

Application

Fantech FKD direct drive, mixed flow fans blend the high air flow of axial fans with the higher pressure, non-overloading characteristics of backward curved impellers. An excellent choice for exhaust or supply applications where quieter performance and easy installation are important. Perfect for commercial and institutional structures such as offices, hospitals, beauty salons, veterinary clinics as well as residential applications such as kitchen range hood exhaust.

Design

The casing is manufactured from galvanized sheet metal. The Series have external rotor motors with a mixed flow impeller, which reduces the external dimensions of the fans. Brackets are supplied with the fans to make installation easier.

Motor protection

To protect the motor from overheating the fan has integral thermal contacts with leads to a motor protection device.

Description

A mixed flow centrifugal type exhaust/supply fan for moderate size ventilation applications specifically designed to bridge the transition from centrifugal to axial. FKD Series fans offer substantially quieter performance and are easier to install than axial arrangements. Fans can be mounted at any angle in any point along the duct work and straight-through air flow design allows easy installation. Fans can be easily removed from duct work for service. Fan motors are capable of operating in air stream temperatures of 140o F. Motor bearings are a permanently sealed, self lubricating ball type. All fans are 100% speed controllable through a decrease in the voltage by using a solid state or transformer type control. All FKD Series fans are backed by Fantech’s Three Year Warranty.
