SF Series - Slimfit Duct Regulating Dampers

Control Options

Option E - Extended Spindle

When the specification requires the Slimfit Regulating Damper to be supplied for motorisation by others, BSB_supplies the damper with a 12.5mm diameter spindle, 55mm in length.

Option H - Hand Control

The unique hand lockable quadrant has infinite adjustable settings and is supplied complete from the factory.

When the specification is amended from Option “E” to Option “H” (regardless if during manufacture or after delivery), conversion is easily completed.

Notes: The quadrant handle when moved fully to the left or the right, will overlap the damper face and consideration should be given to the mounting position of the damper so as not to interfere with its operation.

The operating drive spindle will always be fitted to the second blade down as standard unless otherwise specified.

Option M – Electric Motor

The SF Series Damper can be supplied with the following control motors fitted:

  Open/Close operation

  Spring Return operation

Please be aware that some motors may have a greater depth than the damper that they are being fitted to and when fitted, may compromise the damper installation.

Option P – Pneumatic Actuator

Where pneumatic actuator control is required, you will be referred to the BSB HD Series damper. Please contact the BSB sales office for further details.
