MP Filtri Clogging Indicators

Filter elements are efficient only if their Dirt Holding Capacity is fully exploited. This is achieved by using filter housings equipped with clogging indicators. These devices activate an alarm when clogging causes an increasing pressure drop across the filter element, warning before the element becomes fully clogged.

MP Filtri offers indicators in the following designs:
Vacuum switches and gauges

Pressure switches and gauges

Differential pressure indicators

Vacuum Indicators
Used on the suction line to check the efficiency of the filter element by measuring pressure downstream of the filter. Standard models feature R 1/4” EN 10226 connection. Variants with R 1/8” EN 10226 connection are available for MPS series.

Barometric Indicators
Used on the return line to check the efficiency of the filter element by measuring pressure upstream of the filter. Standard models feature R 1/8” EN 10226 connection.

Differential Indicators
Used on the pressure line to check filter efficiency by measuring the differential pressure (upstream and downstream) across the filter element. Standard items come with special G 1/2” size connections. Stainless steel models are also available.
