Protect your manufacturing process with Kojair TANK CLEANER

Clean replacement air for your product and raw material tankstank cleaner

When the slightest impurity could contaminate an entire production batch, ensuring the cleanliness of the air in the tank is of utmost importance.

Kojair Tank Cleaner flushes the tank interior with a clean, extremely efficiently filtered air flow, thus preventing bacteria, mold spores and other harmful particles from entering the tank. At the same time, Kojair Tank Cleaner ensures that replacement air is always available in any situation, thus preventing the tank from becoming underpressurized.

Kojair Tank Cleaner can be attached to product and raw-material tanks of all sizes, e.g. in the food-processing and pharmaceutical industries.

Kojair Tank Cleaner consists of a blower/filter unit and fittings for the replacement air duct. The parts are connected on-site with stainless steel or plastic ducts. The fittings act both as inlets and outlets for air. A slight overpressure of clean air is formed inside the tank, which protects the contents of the tank from contamination and at the same time minimizes the chance of the replacement-air inlet getting clogged.

Our special product line contains various alternative standard models. If necessary, we can easily customize a solution to fit your needs exactly. Kojair offers suitable and economical solutions for protecting your products against contamination.
