Hydra series are heavy duty wet & dry vacuum cleaners. These vacuum cleaners are equipped with Ring/Regenerative blowers made of aluminium casting. These blowers create high vacuum and airflow to collect all kind of wet & dry dust. The dust is conveyed through flexible hose and it enters tangentially into the filtration drum through an elbow arrangement in which the velocity of heavier and wet particles are nullified and the same settles down in collection tank and the fine dusts are filtered by pleated filter bag. The dust which escapes from the filter bag is arrested by high quality cartridge filter. A collection tank is provided for collecting the dust which makes draining of dust easier.
