New Pump Stone Particulate Filters

Written by I. Stewart | July 24, 2025

We are now offering a new pump stone particulate filter product. This new pump stone particulate filter replaces our previous version, which no longer met Blackline’s high standards for performance and reliability. We’re confident that the new filters will deliver consistent performance in the field.

What’s Changing?

You can purchase the pump stone particulate filters in a 5-pack kit (ACC-PUMP-STONE5). We are also introducing a new 1-pack kit (ACC-PUMP-STONE1), giving you more flexibility to order what you need. As before, a single filter will continue to be included with G7 pump cartridge shipments.

What Does This Mean For You?

The price of the pump stone particulate filter has increased. This change reflects increased costs of materials and supports our commitment to maintaining high product standards. Please reach out to Blackline Safety Technical Support for pricing information.

If you still have the previous pump stone particulate filters, you can continue to use them. If a filter is defective, the pump block test—activated each time you turn on G7’s pump—will immediately detect the issue and the pump will not pass the test. If the filter passes the block test, it is not defective. Please dispose of any defective filters.

If you purchased the old 5-pack kit and the filters are defective, please contact Blackline Safety Technical Support for assistance.
