Abstract

Filter is for use on air conveying systems and has a reverse jet cleaning action. This is provided by the conveying air fan via a changeover valve, operated by a solenoid and is attached to the inlet and outlet ports of the fan. The valve consists of a shaft to which are attached three plates. These plates are spring loaded as is the rod itself. The springs assist the action of the valve and allow the outlet air from the fan to be diverted onto the reverse jet cleaner. The device is for use with air conveying systems, and avoids the use of a pheumatic cylinder.
