VFS-PRE-FILTER SYSTEM

The VFS is an extremely compact, autonomous multi sample filter for flexible construction of a wide range of test set-ups. Connection to the VFS is simplified by a control unit that is integrated into the device and carries out all internal control and regulation tasks as well as communication with the test cell environment. For this reason the VFS is ideal as a replacement for older, maintenance-heavy pre-filter modules. Thanks to its versatility, it can be added to the test cell with limited modification work. - An investment that quickly pays for itself. The VFS has extremely uniform heating and an optimized gas feed that guarantees the greatest precision with measurement results.

The VFS is fitted with an NC pressure governor for max. 50 mBar outlet pressure with an inlet pressure of up to 6 bar. Furthermore the device has a backflushable filter chamber with an inbuilt purge air outlet plus a test gas inlet. All inbound sample gas lines can be separately backwashed. All IAG devices use the same bit coding.

SCP (SYSTEM-CONTROL-PANEL)

Parameterisation is very simple to carry out via an SCP (system control panel). The SCP autonomously recognizes which device it is connected to and enables every device parameter to be set via an extremely clear, self-explanatory display on a 5.7” touch screen. The SCP is also available as a simple software tool. This means that the VFS can be connected directly to an internal network and controlled or configured from any PC. Control can optionally be bit parallel or via Modbus TCP.

If an VFS is connected to an IAG measuring unit, configuration and monitoring can be carried out via the measuring unit display.
