Manually Empty Small Bags with Ease and Efficiency and Capture All Product for Use in Your Process

Bag Dump Station

Bag dump station with reverse-pulse jet filter automatically captures dust and returns it to your process

Collect Dust – Keep Plant Safe, Clean, and Efficient. Our manual dumping stations allow for effective emptying of small volume bags of bulk solids or powder while mitigating loss of product through dusting. Dust is naturally generated when material is emptied from bags, boxes, drums, and other containers, into the collection hopper. Our Bag Dump Station with integral dust collection system reduces material waste and eliminates the need to continually clean or have a remote dust collection location. Effective dust collection protects against creating explosive environments and while reducing contamination and capturing all product for use in your process. Our complete bag dump station with integral dust collector will optimize your small batch material handling process. Centrifugal blower with reverse-pulse jet filter automatically captures dust and returns it to your process.

Plant Safety - Know Your Risk

Dust Explosion at Manufacturing Plant

April 14, 2016 - Investigators said dust from a broken hose is likely the cause of a dust explosion at an International Paper cardboard box manufacturing plant in Richmond, MS early Thursday morning, The Jackson [MS] Clarion-Ledger reported.

No injuries were reported as a result of the explosion, which occurred at about 12:30 a.m., the Clarion-Ledger reported. Small “spot fires” were extinguished by firefighters after the blast.

next: Dust Collection Operation


Dust Collector with operator.To operate a bag dump station, your operator will open the hopper lid. The gas cylinders will allow the heavy-duty door to be lifted with ease and firmly maintain an open position. While material is dumped through the hopper screen, the airborne particles are drawn into the dust collection filters. Selecting your bag dump station with a reverse-pulse filter cleaning system further reduces material waste. The timer-activated solenoid valves release short blasts of compressed plant air inside the cartridge filter. This causes the dust build-up on the filter surface to fall into the hopper. The two filters are alternately blasted at timed intervals, providing an automated maintenance operation. The combination of bag dump station with integral dust collection system helps to protect workers, mitigates plant contamination, and reduces material waste.

Custom features will meet all of your small batch material handling needs.

  • Dust collection hood.Hood configuration for dust control - external collection or self-contained collection using a centrifugal blower.
  • Maximize station operation with an Integral bag compactor - Allows empty bags to be easily maintained and disposed
