Insertable Dust Collector
An upgraded version of the insertable dust collector features improved filters and a smaller footprint to control airborne dust at belt conveyor loading points and other bulk material handling operations. The unit features smaller filter elements that are approximately one-eighth the size of the filter envelopes of the previous system. The mesh-like material filters better and lasts longer while consuming less energy than conventional filter bags. The upgraded filters allow a reduction of the size of the fans used to move air through the filter elements and therefore reduce the power consumption of the collection system.

Bin Vent/Dust Collector
The Modu-Kleen bin vent/dust collector is designed to vent bins, storage silos, mixers, blenders, pneumatic conveying systems of any type, or any other device or process that must contain or control dust particles. It can meet the most stringent air pollution codes, is controlled by solid state electronics, and is self-cleaning for minimum maintenance. Built as an integral part of the bag cage, the cone jet diffuser directs a shock wave of air down the entire length of the bag during the cleaning cycle. This shock wave improves the unit’s efficiency when compared with other venturi type dust collectors that direct the shock wave over only a portion of the bag. The filter bags are cleaned one row at a time, so the unit can operate continuously. There is no need to shut down for cleaning.

Insulated Cyclones
Insulated dust collection cyclones efficiently and safely handle dust in high-temperature applications. Insulated HE (High-Efficiency) series cyclones serve as primary receivers in dilute-phase pneumatic conveying systems where conventional filter receivers might get plugged or overburdened by large airborne solids conveyed at extreme temperatures. Insulated units feature 3 in. of specialty insulation, plus an additional layer of steel. They can be custom built to meet users’ needs. Various types of insulation, including mineral wool or fiber glass, can be used to suit the application. The cyclones operate without any filter media to clean, replace, or maintain.

Filter Receiver
The Filtair series filter receiver provides automatic reverse-jet cleaning of filter media during the gas or material separation process in a vacuum or pressure transfer system. The tangential inlet, located in the receiver’s circular hopper, provides a cyclonic separation of the material or airstream. Airborne material is trapped by the filter elements. Timed, compressed air pulses clean the elements, dropping the once airborne material into the hopper. A single row of elements is cleaned at a time, leaving the remaining filters on-line. The filter elements are protected from the material mainstream by a deflector shield. Efficient performance of the filter receiver is achieved through the proper selection of filter media and the correct air-to-cloth ratio along with can velocity considerations.

Closed-Cycle Dust Collection System
This integrated, closed-cycle material dust collection and recovery system is available for the company’s full line of bulk bag dischargers. The process encloses the bulk bag spout within a sealed containment cylinder. During discharge, migrant dust is contained and kept from spreading throughout the work area. Contained dust is extracted from the cylinder using a point source dust collection unit. A variable frequency motor/blower draws material from the cylinder and into the MERV11-rated filtration stage where material as small as 1 µm is recovered. A high-pressure blast of air pulses the filter to remove the material dust for reintroduction into the process operation.
