The Norgren Ecology Seal is an optional feature in P-Series NFPA Cylinders (EP, EDP). What is it? The Ecolgy seal is a specially engineered piston seal designed to absorb energy and reduce vibration in high speed applications. When used in conjunction with the ACS cushion, the Ecology seal enhances conventional cushioning technology to improve end of stroke deceleration. Eliminates piston impact and absorbs energy at the end of stroke! Benefits > Absorbs energy, eliminating impact forces, reducing vibration > Reduces noise by 25% > Reduces time through cushion to decrease cycle time, increasing productivity Application Tips Use an Ecology Seal cylinder… > In high speed applications when load deceleration is a concern > When excess machine vibration due to pneumatic components is a concern > When cushions are required, but speed cannot be sacrificed > To reduce the effects of pneumatic bounce > To reduce noise levels Noise Reduction Sound Levels in Decibels PSI Air Sound Presure level in Decibels 2.00" x 6.00" Cylinder Standard Seals Ecology Seals 95 End 110 74 PSI Side 110 81 50 End 113 74 PSI Side 110 81 Note: These figures are for new cylinders. The impact dampening seals will take some compression set during operation of the cylinder and stroke loss will decrease. Also, the pressure for zero stroke loss will decrease to about 80 psi. To determine the stroke loss for either head or cap end, divide the values shown by 2.
