Description

APPLICATIONS
Supply and exhaust ventilation systems for various premises with a limited mounting space.	Designed for connection with 400200, 500250, 500300, 600300, 600350, 700400, 800500, 900500, 1000*500 mm rectangular air ducts.
DESIGN
The fan casing is made of galvanized steel.	VKPFI models are heat- and sound-insulated with 50 mm layer of mineral wool.
MOTOR
The impeller with forward curved blades made of galvanized steel is powered by 4- or 6- pole external rotor asynchronous motor. Such modification ensures high air flow capacity and relatively significant differential pressure. For thermal overheating protection the thermal contacts with leaded outside terminals are incorporated in the motor winding for connection with the external protection devices.	The motor is equipped with the ball bearings for long service life. For precise features, safe operation and low noise, each impeller is dynamically balanced while assembly. Motor protection rating IP 44.
SPEED CONTROL
Smooth or step speed control with a thyristor or autotransformer speed controller.	Several fans may be connected to one speed controller provided that the total power and operating current do not exceed the rated speed controller parameters.
MOUNTING
The fans are designed for inline rectangular air duct mounting and require no special fixing in case of direct connection. In case of connection through the flexible connectors the fan is fixed to a building by means of supports, suspension brackets or fixation brackets. The fans can be mounted in any position with respect to the pointer direction on the casing.	Access for the fan maintenance shall be provided. The fan is powered through the external terminals. The casing is provided with the removable access door for maintenance.
