Lever feature also allows for a secure seal with a reduced risk of the lid unscrewing. LONGER LIFE: Cyclone separators help preserve filter life and reduces the risk of motor failure due to airflow restriction through the vacuum motor because of clogged filters. COMPACT UNIT: Once you have assembled your separator with 19l collection bin, it will sit at approximately 73cm in height with a diameter of 37cm. This compact unit can be stored under work surfaces and hidden away for a seamless and clutter free dust collection system.
