VARIO Low pressure cleaning technology

 

Gentle cleaning technology for: The restauration of facades, monuments and buildings, natural stone, bricks, graffitis, hard and soft wood and fire damages.

The advatage of  SAPI „VARIO“ low pressure cleaning technology

- gentle to the environment and to the building material - applicable for low- and high-pressure from 0,1 bar - cleans dry and wet, high performance - minimum  durch optimierte Düsen- und Gerätetechnik

SAPI „VARIO“ nozzel technology: 3 different sandblasting methods with one basic nozzle.

Using the "VARIO" –  soft blasting nozzle-technology, you can choose between 3 blasting methods by using only one basic nozzle. So you can adapt your equipment quickly to the necessities of sandblasting, according to the surface to be cleaned and to every typ of paint or incrustations which has to be removed. Changing the components of the basic nozzle, you can use it as a vortex, flat stream or round stream (venturi-type) nozzle.

Vortex cleaning technology „The most gentle methode to clean delicate surfaces“

The SAPI - vortex stream methode is working like a cyclone. A special part inthe nozzle brings in rotation the compressed air which flows through the nozzle like in a cyclone. The particles of blasting material strike with lowimpact the surfaces and move in rotating way over the surface to be cleaned. The are erasing and grinding the surface instead hitting it by high pressure, which prevents it from damage. This principle works with different fine blasting materials as stone powder, calcit, olevin etc., depending on the different surfaces which have to be treated. The vortex-stream technique serves best, where you have to treat carefully very delicate surfaces.

Flat fan cleaning technolgy "cleanins biggest surfaces in shortes time“

A special nozzle head with flat flow cannel widens the flow of pressured air and leads the particels of blasting material in a wide, flat stream onto the surface which has to be cleaned. So you can reach a high performance in square meter. Depending on type and grain size of the blasting material you can get different cleaning results.

Round jet cleaning technology „The clasic technology for universial applications"

The Venturi-roundstream technology accelerates the air flow linear and forms a cone-like air-flow. The particles of blasting material hit the surfaces to be cleaned with a maximum speed and the abrasion effect is high. That`s why the venturi - blasting technique shows it´s best result when you have to remove coating of old paint or if you want to make surfaces rough, f.e. if you are treat concrete, steel or plaster.

 

Example of use SAPI „VARIO“ low pressure cleaning technology.

The SAPI "VARIO" mildblasting-nozzle-technique is best for the careful cleaning of buildings, walls and monuments, built of natural stone, bricks or concrete, for surfaces consisting of naturale stone, plaster, structural and sight concrete, wood, steel or other materials. It cleans them efficiently and removes incrustations, graffiti, organic and mineralic coatings, etc..
