MODEL 80 END MOUNTED PISTON VIBRATOR - “BIG RED”:  The new revolutionary lightweight all steel design makes it an inexpensive unit for the big bin or hopper job without sacrificing the quality of the more expensive flange mounted units. The single bolt attachment makes them easy and fast to install. The “BIG RED” is supplied either with a silent (air cushioned) piston or the more powerful impacting (piston hitting end cap) standard unit.  O-rings cover the air exhaust holes keeping dust and dirt out of the piston chamber, avoiding scoring and damage to piston and cylinder walls, and allowing the units to operate in the worst environments.  There are four basic models with piston sizes of 1”, 1-1/4”, 1-1/2” and 2”.  For smaller sizes see Model 70. The eyebolt on top for a safety chain can be removed for other attachments.
