Acid vacuums and caustic vacuums for wet operation

In numerous Ex and non-Ex areas, aggressive media such as acids and alkalis have to be vacuumed. This includes, for example, microelectronics with the manufacture of semiconductors. At KRAHNEN, you can get special acid and caustic vacuums, also ATEX-certified. The liquid suction cups are specially designed to absorb acids and alkalis and offer the highest level of safety. The alkali and acid-resistant industrial vacuum cleaners are available as a mobile solution with electrically conductive rollers, for example for emergency operations, or as a stationary unit. The industrial vacuum cleaners are available as electric or compressed air models. The models are also ideally suited for maintenance cleaning.

Easy to configure thanks to the modular principle: acid and alkali vacuums

Thanks to the modular principle, our acid and caustic vacuum cleaners can be easily put together for individual applications. The alkaline and acid-resistant wet vacuum cleaners are available with parts in contact with the medium made of stainless steel, polyethylene, polypropylene or polyvinylidene fluoride. The tanks can optionally be equipped with drainage taps made of PVC, PP, PE or PVDF. Thanks to the optical level indicator, you can easily keep an eye on the current level. The practical float switch-off prevents the acid and caustic vacuum cleaner from being overfilled.

The container can be safely emptied via the special ball valve. We offer you various types of activated carbon filters with different degrees of adsorption for maximum safety. Activated carbon filters adsorb the gas content dissolved in the intake air. For example, an integrated coarse dirt basket with a disposal system separates solids from the liquid and relieves the filter.

Choose the right variant for your needs from our wide range of options. Feel free to ask us about our extensive range of accessories. This allows you to adapt the acid vacuum cleaner or lye vacuum cleaner to your requirements even more flexibly.
