Hazardous and Combustible Dust ControlCompatible Products

Combustible dust can be formed by milling, sanding, grinding, crushing, cutting or simply handling material that is in
powder form. In 2008, following several news-worthy mill explosions, OSHA reissued CPL 03-00-008, which outlines recommendations and guidelines for decreasing combustion risk. Safety organizations continue to focus on
this problem and the ways to reduce it. Both OSHA, the FDA and NFPA prefer housekeeping methods that employ vacuum. Hoffman & Lamson central vacuum systems offer advanced explosion proof valves, panels and other features for the ultimate safe and clean environment.

Ethanol Production Compatible Products

Hoffman & Lamson products can be used in the various stages of ethanol production. 

Carbon dioxide is given off during the fermentation stage or ethanol production, and some plants collect and market the gas. To do this, the gas must be removed and stored under pressure. Hoffman & Lamson multistage centrifugal blowers are used to draw off the carbon dioxide and transport it for storage in pressurized cylinders.

To maintain a clean and safe working environment ethanol facilities use robust Hoffman & Lamson vacuum systems. Not only does this keep the receiving and storage areas clean, but it keeps the facility free of combustible dust , and compliant with OSHA regulations.

Flux RecoveryCompatible Products

Hoffman and Lamson flux recovery systems remove unused flux, slag or fused particles from the work and separate the slag-free flux into a hopper for future use. Removing the flux dust results in cleaner welds, fewer rejects and increased production.

Housekeeping - Commercial & IndustrialCompatible Products

Hoffman & Lamson engineers custom central vacuum solutions for cleaning industrial facilities and commercial buildings.  From large multi-operator systems, to portable units, we offer complete system packages including hoses, tools and accessories to keep your facility clean and remove dirt and hazardous dust. 

Pneumatic ConveyingCompatible Products

In pneumatic conveying vacuum is used to move materials through an enclosed pipeline. In this application no moving parts touch the materials, dust is contained within the system and contaminants are unable to enter the closed system. Pneumatic conveying is often used to transfer bulk from storage to process, and is often used in food and other applications where safety and hygiene as a concern.
