In addition to the material-from-air filtering that occurs within the receivers, in-line filters are available to provide additional blower protection from material fines that may carry over to the blower's inlet if left unprotected. They are located downstream from the conveying equipment, in front of the blower package.

Modular In-Line Filter

The modular in-line filter contains a manually-cleaned cartridge, and has a quick-access cover for easy filter inspection and maintenance. The material discharge gate also opens easily without tools. The filter is available in 10-inch and 15-inch diameters, and is constructed of aluminum. Brackets are provided for wall mounting.

Pulse-Clean In-Line Filter

For more demanding filtering situations, the pulse-clean in-line filter can be used where frequent manual cleaning of the modular unit would not be practical. Its filter bags are automatically pulse-cleaned during periods when the system is not conveying. The unit is shown with the optional fines collection kit that fits beneath the filter. It collects the fines trapped by the filtration system to help keep the process area clean.

Modular In-Line Filter Group

The in-line filter group includes a modular in-line filter, a flexible rubber hose on the inlet and outlet, and a support stand. This assembly is available for three-inch, four-inch, and five-inch line sizes.

Cartridge In-Line Filter

The cartridge in-line filter contains a cartridge filter element that is accessible for cleaning or replacement through bolted access plates. The unit is available in a wide range of sizes. Materials of construction include carbon steel, stainless steel or aluminum.
