They are manual parts washer tanks made entirely of AISI 304 stainless steel and are indicated for those who have to wash particular mechanical parts, small parts or work equipment manually. They adapt to any workplace due to their small size. They are environmentally friendly because they use aqueous, non-foamy, biodegradable detergents and save energy through their foot pedal operation that drives the pump directly, allowing the operator to use it only when necessary and facilitating his/her work, and exempting the operator from having to use an uncomfortable and tiring hand control.
