The Wichtia Air-Tube Disc Clutch incorporates the best features of the disc type clutch and benefits of direct air engagement. It uses the most effective way in order to apply air pressure, operating through direct axial pressure application by compressed air in a soecial composition full-circle tube, providing smooth operation with no activation noise, shock or impact, with full release in under a second. This efficient operation is owed to the small volume of needed air. The clutches are also capable of moderate slip, providing improved acceleration control. This operation enables easier handling of large inertia loads, when using electric motors, as it keeps power needs below allowed maximum, via smooth and accurately controlled slip starts. In order to maintain reliable operation during controlled slipping and high cycle rate operation, these unit feature centrifugal blower design, allowing fast an reliable heat dissipation. These low and very low inertia units, offer full freedom from centrifugal force and self energization effects.
