Indication of clogging of the filter element

Air filter cartridge contamination indicator
	a simple mechanical device for optical signalling of clogging of the liner also helps to reduce energy consumption by providing early warning of high pressure gradients in the filter if the filter cartridge is clean, it displays green; otherwise red top-mounting of all AF filters except AFA activated carbon filters
Order number	Green area bar	Red area bar
PDI	0 - 0,6	0,6 - 0,9

Differential manometers MDM40
	magnetic differential pressure gauges for displaying the orientation state of the filter cartridge equipped with a dial with an indicative scale and a green/red field MDM40: basic design MDM40C: version with voltage-free electrical contact for remote alarm signalling
