Performance Curve - TD-EVO-250VAR

Description

The TD EVO VAR in-line fan has been designed to provide highly efficient, mixed-flow performance with low energy consumption for domestic and commercial applications. It takes advantage of an integrated variable speed controller that can be adjusted locally on the fan, or remotely via a 0-10V or 4-20mA analogue input signal.

The TD EVO VAR also comes standard with an on-board, adjustable 1 to 30 minute run-on-timer that allows steam and odour to be exhausted after leaving the room.

There are 6 models in the range matching standard duct sizes from 100 to 315mm diameter.
