GEMMA is produced in two different typologies: first, with handling discharge of dust container; second, named ‘DSA’, with automatic discharge of dust container, high 145 cm from the ground.
The chosen technical solutions and characteristics put GEMMA at the top position in the market range of the actual produced machines, with a remarkable quality / price relation. Besides being, basically, a ‘Poli’ machine, for this having an electrically welded iron frame, painted in oven with epossidic dust paint, GEMMA E78 (battery version) possesses following characteristics:
 
Traction is obtained by frontal electro-motor wheel with 1.200 W triphase AC vertical motor, this permits maximum angle rotation during steering. For this, Gemma can rotate on itself, so it’s possible use it for clean in limited spaces. Maximum speed is 7 Km/h, assisted by an automatic system for reducing speed while curving.

It’s easily handled, because it has great diameter super-elastic wheels, anti-trace standard wheels on battery version.

Braking system with double drum on rear wheels.

Electronically controlled speed by an electric chart with a 300 Amps. of current capacity, to go up ramps over 20% standard

The electric suction fan is placed on the filter compartment for a clearer separation between the suction part and the engine compartment.
Filter for the standard version is an M-class sack filter, available in different substances and treatments, it has a 5,5 m2 surface and cleaning is obtained by an electric vibrator. There is also a cartridge filter version with washable filters for a 6,4 m2 surface, also equipped with an electric vibrator.

Main brush and side brush are replaceable without using tools.

Dust container capacity is 115 lt. It’s also possible, for the handling discharge container, have nr. 3 plastic reduced containers inside the main container, to make easier the discharge.

It’s possible to do a fast batteries change, for they are placed in a steel case, extractable from the side of the machine.

Protection front disks in anti-trace gum.

It’s possible to lift the machine for transport and to anchor it from the sides.

Front working lights, flash, ergonomic commands, adjustable seat, hour-counter, battery-level indicator (for E78), claxon are all standard equipment.

Recommended for surfaces from 3.000 to 5.000 sm
