The INV2.60 and INV3.100 SE/SEA are single-phase wet and dry vacuum cleaners; they offer greater control of the outlet air and greater practicality during maintenance operations. They are available in the SE (with an electric filter shaker activated by means of a handy button) and SEA configurations (with a sophisticated filter cleaning system).

The versions with automatic electric filter shaker (SEA) can work in 3 distinct modes:
Manual mode
With the motors switched on, by pressing the filter shaker button you can interrupt motor functioning and begin a 20-second filter cleaning cycle. When the cycle has finished, the motors start up again automatically.
Semi-automatic mode
Every time all the motors are switched off, a 20-second filter cleaning cycle begins automatically.
Automatic mode
When the filter becomes less efficient, motor functioning is automatically interrupted and a 20-second filter cleaning cycle begins. When the cycle has finished, the motors start up again automatically. These vacuum cleaners can be fitted, upon request, with class M, antistatic and anti-heat filters and a mechanical or electronic float.
In addition, a HEPA cartridge filter (essential when removing microdust) can be fitted, upon request, for the inlet air, drum outlet air, and motor cooling air.
