Safe storage of aerosols
April 1st 2005

Pressing Solutions, in conjunction with Advantage West Midlands Innovation Networks’ Innovation scheme, has developed an aerosol piercing and filtration unit that de-gases empty aerosols and contains and filters the propellant.

Constructed of stainless steel with brass piercer, the handle is depressed to pierce the aerosol and the propellant is directed into the bottom chamber, passing through carbon packs of varying sizes to extract as much as possible before being allowed into the atmosphere.

To aid movement, a small air flow is introduced with the pump sited away from the piercing unit.

Alternatively, it can be connected to its own air supply.

A second version is being developed for paint/liquid aerosols containing small residues.

There is a pierced bottom to the chamber that allows paint/liquids to enter the bottom unit and be drained into a suitable container.

The unit is designed for paint/chemist environments where propellants can be dispersed through the normal extraction system.
