Exhaust columns
Exhaust columns are used to remove exhaust air from the room. The design of the exhaust unit provides additional installation of an air filter element. They are used for the needs of different types of industrial enterprises, different types of laboratories and various health care facilities. For the needs of industrial enterprises, exhaust columns with exhaust air intake from the lower zone (100%) are usually used. Exhaust columns with exhaust air intake from the lower and upper zone (60% from the lower zone and 40% from the upper zone) are usually used for the needs of health care facilities. They are made with the increased requirements to tightness.
Selection of exhaust columns and their installation in the premises is carried out individually for the needs of the Customer.
Exhaust columns consist of a decorative element of wall structures, an adjustable air distributor (air distributors), a ventilation grille (ventilation grilles) and elements of fastening and connection to the ventilation and air conditioning system. They can have both a standard floor version and a corner version.
Exhaust columns are mounted in the appropriate wall structures, by hidden fasteners.
The joints between the individual elements are additionally sealed with a silicone-based sealant with guaranteed quality.

The elements are covered with powder paints, sintering method. Coatings characterized by superficial hardness, resistance to treatment dis infecting solutions, is not conducive to the formation of cracks and generation of microparticles from the working surface. The color of the coating can be selected according to the RAL colors for powder paint.
