3.4.2 - Filters
M5 HEE filter
Thickness: 48 mm
Fire rating: M1
Single filtration
Filter Dimensions x Number of cells/air flow
Dual filtration
When dual-stage filtration is installed, the two stages of cells are installed on the same runner.
Recommended fouling level value
The pressure switches installed enable a filter fouling warning to be issued. They are factory-set, based on:
• the unit size
• the selected flow rate
• the filter efficiency
The graphs below give values which enable the actuation threshold for the pressure switches to be defined based on the selected flow rate.
