DOA: RANGE OF VENTILATORS/ASPIRATORS

Their use of ventilation and safety in closed space is mandatory and prescribed by law before, during and after works in environment that can be dangerous , toxic, flammable or explosive like tunnels, basements, manholes, silos, holds, tanks, petrochemical plants, wells, fuel stations, warehouses , mines, laboratories , confined space excavations, sewers ducts, gas distribution networks etc .

The anti explosion proof model AV28 ATEX is irreplaceable when is needed to operate in presence of gas and vapours explosive or flammable.

Extremely light can be used in different positions or used with or without the flexible air hose. The air hoses are necessary to direct, transport and suction of the air IN or FROM a precise point, without the hoses can be used just like positive ventilators to supply a powerful direct “wall of air”.

The exclusive DOA system to fix the hoses on tools allows a quick installation on the mouth by simply “button up” the hose edge on pins only by hands without needing screw drivers or belts/clamp.

The volute and air fan can be washed up without problems as are in polyetilene, maintenance necessity is minimal.

Very robust thanks to the construction in polyetilene and stainless steel are invulnerable to impacts rust water and from the corrosion of the majority of acids and chemical agents.
