Custom Hood Options

55 Gallon Drum Hood

Aerodyne’s 55 gallon drum hood is ideal to capture fugitive dust released during filling of a 55 gallon drum. The hood, constructed of carbon steel, surrounds a portion of the drum allowing any dust escaping the top to be picked up and sent to the dust collector.

Custom hood designs are available upon request, including stainless steel construction or special duct connections. Aerodyne also offers custom fabrication drawings for fab shop customers.

Frequently Asked Questions

A dust collector hood is the capture device located at the source of dust generation that directs airborne particles into a dust collection system.

It is positioned near the point where dust is created so contaminants are captured before dispersing into the facility. The hood’s design determines how effectively airflow pulls particles into the ductwork, which directly impacts system efficiency, worker exposure levels, and overall air quality. Improper hood design can reduce capture velocity and allow dust to escape into the workspace.

Aerodyne Environmental provides custom hood design, engineering calculations, and fabrication services for industrial dust collection systems.

These services focus on developing source-capture hoods that match specific process conditions, airflow requirements, and material handling needs. Proper hood sizing and placement are determined through airflow calculations to ensure adequate capture velocity and effective containment of fugitive dust.

Available hood services and options include:

  • Custom hood design and engineering – Airflow calculations and fabrication drawings based on process requirements
  • Drum filling hoods – Source-capture hoods designed for 55-gallon drum loading and material transfer operations

Application-specific fabrication – Hoods built for conveyors, grinding stations, mixing areas, and other dust-generating processes

Hood design affects dust collection performance by determining how effectively airborne particles are captured at the source and directed into the ductwork.

The shape, size, and placement of the hood influence airflow patterns and capture velocity, which control whether dust enters the system or escapes into the workspace. A properly engineered hood minimizes required airflow while maximizing containment, whereas poor design can increase system airflow demand, energy consumption, and dust accumulation in ducts.

Key performance factors include:

  • Capture velocity – The airflow speed required at the dust generation point to pull particles into the hood
  • Airflow efficiency – Proper sizing reduces total CFM demand and fan workload
  • Hood placement – Position relative to the dust source affects containment effectiveness

Maintenance impact – Inefficient capture can lead to duct buildup and increased cleaning frequency
