A sanding machine with a hand held sanding unit connected to a base unit, containing one motor that has several purposes: to provide suction of debris back to the base unit through a hose, to power a driver cable that rotates the hand-held unit and to produce vibrations needed to cause the filters to release accumulated debris, whereby three motors are not necessary as in my prior U. S. Pat. No. 6,315,647 issued on Nov. 13, 2001.

This is a working post to be utilized for all those functions where air circulation is suggested or required. It is comprised of three main parts: an airflow generator, which is connected to an air filtering hollow floor and to an air and light filtering hollow roof. The working area is the space between the floor and the roof. The airflow generator contains only one motor that powers simultaneously two fans. It does not need a floor pit nor wall plenums to achieve an extremely efficient, powerful and uniform downdraft air circulation in the working area, and to allow the attainment of a superior finish of the object while providing a clean environment for the operator. It is also simple to operate, cost effective, space effective and energy efficient.

This is a compact apparatus for generating a hot airflow to be utilized for all those functions where a hot airflow is suggested or required as, for example, in prep stations, spray booths and mix rooms. An outer air duct, that has one of its end closed, contains a second, smaller air duct that houses a fan, powered by a motor, and a gas burner. Cool air enters the outer air duct, passes through the warm hollow space between said two air ducts, goes through said burner located inside the inner duct, and hot air exits from the inner air duct. It is energy efficient, simple to operate, cost effective, and space effective.

A sanding machine with a hand-held sanding unit, with interchangeable heads, connected to a base unit, containing three motors, one to provide suction of debris back through a hose, which has an inner hose containing a driver cable and self lubricating material, which allows the transportation of debris back to the base unit collection unit, connecting the base unit and hand-held unit, a second motor to power a driver cable which turns the hand-held unit, a third motor which is encased inside a collection unit, inside the base unit, which generates electromagnetic vibrations causing filters to release accumulated debris by the interaction of an inner and outer spring.
