Silvent 703

SILVENT 703: specially made entirely of stainless steel with aerodynamic slots to allow optimal utilization of compressed air while keeping the noise level to a minimum. The high ambient temperatures of a glass works, the extreme blowing forces used in a steel mill or the stringent hygienic requirements of the food processing industry are examples of typical areas of application. Blowing force approx. 3 times stronger than SILVENT 701 (9.6 N (2.1 lbs)). Part of SILVENT's 700 series, together with 701, 705, 710 and 720. Fully meets OSHA safety regulations and EU Machine Directive noise restrictions.
