Solbert Filters - STS series

Solberg STS Filter – Perfect for Vacuum Pumps

What process filters work well with Vacuum Pumps?

The Solberg STS Series filters prevent liquid slugs from entering the vacuum pump – inexpensive protection against catastrophic failures.

How the Solberg STS Filter Works

Inlet air with potentially harmful liquid and large particulate enters the housing and is separated by a baffling mechanism and directional air flow changes. The larger particles and liquid drop down and collect at the bottom of the separator. The float capsule within the separator screen rises with the liquid level until max capacity and limits the flow, thereby protecting the pump from damage.
