Foam Oscillating Units

Low Expansion Synthetic Fluorine Free Foam (SFFF) systems are comprised of various FM Approved and/or UL Listed components to establish a complete package for flammable liquid protection. Included in the package are foam monitors, which effectively cover large application areas with water or a foam solution!

Manual or oscillating monitors are usually part of a fixed deluge or flow control system but can also be supplied locally via hydrant or fire truck hose supplies, and can also be mounted on mobile trailers for greater versatility in challenging fire scenarios. Foam monitors are used in areas such as ignitable liquid storage tank farms, loading racks, incineration facilities, recycling plants, aircraft hangars, helidecks and jetty protection applications.

Viking offers the Model VMT, VMH, VMW Monitors, the Model VNN, VNS Nozzles, and the Model VSO Oscillating Unit.
