The Bosch VB170 Filter Bag is a replacement bag for the Bosch’s GAS20-17A dust extractor. It is a three-layer bag designed for heavy loads. This bag acts as a preliminary filter, capturing most of the debris and dust. This helps to increase the life of the main filter. Using a filter bag is an efficient way to dispose of the captured dust and debris. The bag has a port cover to securely close the bag during the disposal process. The VB170 is for dry use only and will be damaged by wet-vacuuming.

• Helps with OSHA compliance – when combined with the GAS20-17AH dust extractor and a HEPA filter, the VF170 can help move users toward compliance with the OSHA respirable crystalline silica dust regulation.
• Preliminary filter – captures most of the debris and dust and increases the life of the main filter.
