A vacuum cleaner pre separator is a component in some vacuum cleaning systems that separates larger debris and particulate matter from the air stream before it reaches the main collection container or filter. The pre separator acts as a pre-filter, trapping dirt, dust, and other larger particles before they can clog the vacuum’s main filter. This helps to prolong the life of the main filter and ensure that the vacuum continues to operate effectively. By using the most other regular separator , the operator have to turn off the vacuum to let the dust drop down into the bag of the separator when changing bags. While the T05 dust separator build a smart design of the pressure relief valve, which enables any dust extractor to continuously operate with limited downtime, improve the working efficiency. T05 can be lowered to 115cm when in transportation.
