With the development of its new SILOTOP R03 Filter, WAM has set new standards in silo venting. The SILOTOP R03 is reliable, easily maintained and safe. A heavy-duty 304 stainless steel body houses the POLYPLEAT filter elements with integrated automatic pulse jet cleaning system housed inside the weather protection cover. The special design of these tested filter media offers an optimum: filter surface to body volume ratio. To stop the weather protection cover from slamming shut during inspection and maintenance, the hinges automatically lock on opening (autolock).
