Vacuum sets are used in the process of degassing casting materials such as silicone, resin, gypsum and the process of
impregnation of wood and other porous materials.
The vacuum chamber is a sealed tank inside of which it is possible to create a low pressure environment by the suction of
contained gases by the vacuum pump.
The vacuum set is operated in the following conditions: ambient temperature b5°C and +40°C, air humidity up to
80% at 20°C.
Photo 1: Vacuum set.
The vacuum set (Photo 1) consists of a vacuum chamber (2) and a vacuum pump (3) connected by a pneumatic hose (1). The
properties of the Vacuum Chamber are described in the next section of this manual. The vacuum pump included in the standard
vacuum set is a rotary oil pump. In the set, instead of an oil pump, an oil-free piston pump or a diaphragm pump can be used.
This manual describes the installation of a vacuum set which includes an oil rotary pump. In case of using a different type of
pump or a pump supplied by another manufacturer, read and follow the instructions provided with the pump.
VcuumChambers.eu is not responsible for vacuum pumps provided by other manufacturers or distributors. The vacuum hose
included in the set is a reinforced pneumatic hose with a fitting enabling connection to a vacuum pump. The vacuum set is also
equipped with the oil needed to start the pump for the first time (when using a rotary oil pump) and the user manual.
The vacuum set can be equipped with additional elements: a fitting muffler, a stirrer mechanism, a vacuum trap or a
vacuum feedthrough with pouring hose and mechanical flow controller. These elements are described in chapter "5. Additional
equipment. " of this manual.
The vacuum chambers used in vacuum sets vary in size and material. Photo 2 shows an example of a vacuum chamber. The
vacuum chamber body is made of aluminium, powder coated steel or stainless steel depending on its type. The lid of the
chamber is made of thick polycarbonate or tempered glass. The tank is provided with a silicone seal which is durable and has a
low susceptibility to mechanical deformation. Excellent transparency of lid allows observation of the degassing process. The two
ball valves allow to adjust the degassing process, and the mounted vacuum gauge indicates current vacuum in the chamber. The
chamber is equipped with an intake air filter, which effectively prevents dirt getting into a degassing material. The chamber is
attached to the pump with a barb, on which is fitted a reinforced hose with an internal diameter of 8 mm and a length of 1.5 m.
The whole product is made from materials of the highest quality and a branded thread sealant.

Elements 1 to 5 together with pneumatic fittings form an air manifold. It also includes the washer and nut needed for its
assembly. The manifold is mounted on a tank or lid, but due to the risk of damage during transport, it can be attached to the
vacuum set separately. In that case, the customer should mount the manifold on the tank or lid by following the instructions in
this manual.

If the air manifold (Photo 3) is supplied separately, unpack it and remove the nut and washer. Do not remove the O-ring.
The pneumatic fitting, from which the nut and the washer were removed, should be placed in the hole. Depending on the model
of the vacuum chamber, the hole is located in the wall of the tank or in the lid of the vacuum chamber. The manifold should be
located on the outside of the chamber (Photo 4) or on the top of the lid (Photo 2).
