# Hygenic Design Gearboxes – Stainless Steel, ATEX & MIL Versions
Gearbox solutions for special environmental conditions
======================================================
WITTENSTEIN offers perfectly tailored gearbox solutions for drive tasks in special environmental conditions – from food-grade to ATEX-certified.
##### Your possibilities
*Food-grade lubrication* – Many gearboxes are optionally available with food-grade lubrication. Ideal for applications in the food and packaging industry.
*Corrosion resistant* – This option is suitable for applications involving moisture, cleaning agents, or aggressive environmental conditions.
*Hygienic Design* – Here you will find specially developed gearboxes with a hygienic design. They are sized for easy cleaning and to meet the highest hygiene requirements.
*Explosion protection (ATEX)* – We offer an ATEX-compliant version for some gearboxes. This variant is designed for safety in potentially explosive atmospheres. Please specify ATEX requirements in your inquiry.
