Nexen SE 625 883000 - Manual (Page 5)

5 FORM NO. L-20078-C-0210
INTRODUCTION
Nexen’s DAP is a combination air actuated clutch and
spring engaged brake. The unit’s brake remains engaged
until air is applied to engage the clutch. Because of the
internal construction of the DAP, overlap (simultaneous
engagement of both clutch and brake) is impossible. Nexen’s DAP is suited for mounting on standard NEMA
"C" flange mounting faces such as reducer units and
outputs, and motor flanges. An “L” shaped foot is also
available for free standing applications.
