Stainless steel fans
Special fans

Attractive and sturdy: Almost all of our fans are available in stainless steel. Housing elements and fan wheels including the hub and motor shaft can be supplied in V2A steel.
All welded parts are glass pellet-blasted.
Our stainless steel fans therefore meet all your technical and aesthetic requirements. The use of V2A significantly increases the lifetime of the devices – even if used in humid, abrasive atmospheres.

Do you need something really different or an individual production run? No problem! We can work with you to develop solutions that meet your exact requirements.
