Why the Airflex® 200DPA	N/A High quality High performance Low cost of ownership Low maintenance Long lining life
Features	N/A A large piston area and 2000 psi operating pressure range give high frictional force resulting in more torque Base or split mounting for flexibility of mounting and accommodation of different disc thicknesses or diameters to meet diverse customer requirements Guide pins transmit torque from friction shoes which prevents piston seal leakage that could result from misalignment between the friction shoe and disc Large friction area for long life and reduced maintenance due to friction material wear Automatic friction shoe wear adjustment with each engagement Solid or ventilated discs to optimize performance and lining life
Manufacturer	N/A Eaton-Airflex
Actuation	N/A Hydraulic Applied
