Underfloor Systems

The primary reason to use an underfloor system is to provide an exhaust connection, as near to the vehicle exhaust pipe as possible to minimize the amount of hose needed and reduce the hassle in handling the components. This approach is particularly affective in application where low exhaust vehicles are prevalent such as, automobile dealerships. However, underfloor systems are also affective in heavy equipment facilities where overhead cranes interfere with the operation of ceiling mounted exhaust system. By using floor fittings that accommodate larger diameter flexible hose, exhaust connections can be placed strategically to serve large equipment bays without excessively long flexible hosing. In these applications large vertical stack vehicles can be served by the use of a diesel cane in conjunction with a hose assembly from the floor unit.

The disappearing style unit has many benefits and can be used in several different types of facilities. It is an efficient design that will take up very little space, mounting flush to the floor surface, with the hose storing inside the unit. Made from laser cut and machined stainless steel, this rugged design can withstand several tons if driven over. Its unique hinged door swivels and lifts conveniently allowing the door to lay flush. For more information please refer to the Product Catalog within this website or feel free to call the factory or local representative for engineering support.

Plug-In Units

The benefit to a plug-in unit is the flexibility that you have with hose length. It accommodates longer lengths for reach across large bays as well as stack configurations.


As with all Car-Mon products, custom solutions can be provided throughout the range of our product line. With underfloor units the limiting factor is always the diameter, but with the engineering capabilities offered and the control of manufacturing larger diameters can be provided for industries like agriculture and large diesel arrangements. This option allows for easy storage and convenience near exhaust outlets. Please call the factory or your local representative for solutions to your building layout.
