The AV 28-E is a powerful centrifugal ventilator/aspirator. It is irreplaceable when work is being carried out in closed environments containing fumes, exhalations, steams, or toxic and explosive gases, as it guarantees the safety and environment reclamation.
It provides maximum flexibility due to its unique features and rational configuration. The versatile air hoses facilitate quick installation on each mouth as the stainless steel frame can be utilized in two ways. In its normal position, it can be used either with or without the hose. With the hose, the direction of the air in or from an exact position in ventilation or aspiration mode can be given. When bent on a lateral position, the tool can ventilate directly downwards inside manholes.
The impeller and volute are made from a strong polypropylene, plastic material which is exceptionally lightweight and resistant to impacts, has invulnerability to rust and to corrosion from aggressive gases. Spark-free operations are achieved due to the plastic construction which limits any risks.
