Nilfisk and Tellus GS and GM Motor Commercial/Industrial Replacement Silencer
These are the original Nilfisk sound suppressor replacement medium for GSD Motors pods and GM Motor pods on the industrial and commercial vacuum cleaners. This is probably the last one in the WORLD!!
They fit inside the filter cage on top of the motor.
They apparently attenuated the sound level by approximately 4%.
As they're light, maximise the saving on postage and buy some of the related parts below, such as dustbags and other filters or a new hose, a floor tool or other accessories.
At the moment, standard postage within Australia is capped at a maximum of $20!
