The unit is suitable for 500Pa system pressure and tested up to 10,000 cycles including additional cycles 10% under / 15% over voltage. 

The Damper:  The 26SSD comprises of three units, damper, removable sleeve and a grille. The benefit of the units design is that it is simple to install with various options and has easy access to maintain. The internals of the sleeve and damper are painted matt black as standard so they are hidden from view to allow the grille on the face to have the largest free area of 90%. There is sufficient space between the damper and grille to avoid interference with the damper blade operation.
