4.5 Reverse Pulse Filter Cleaning System
The downdraft table is equipped with a reverse pulse automatic filter cleaning system. This system is controlled by a PC
board inside the control box (Labelled “AVP-Z”). Changing the dip switch settings on the AVP-Z board, allows you to
control:
1. Pulsing online or offline
2. Number of pulses
3. Pulse duration
Solenoid operated air valves discharge large blasts of air through the filter cartridges thus dislodging particles embedded in
the filter media. The particles fall into a dust drawer located below the cartridge. The angled v-shaped baffles above the
drawer prevent the dust from re-entering the cabinet when the machine is turned on.
Neglecting to pulse the filter regularly will reduce filter life.
