Blower DOG-1
Drying the firefight hoses
Drying the humid walls
Fresh air supply during rescue actions
Application
DOG-1 blower jest meant for:
– local drying the walls in humid rooms,
– drying the inner surface of the firefight hoses at fire brigades,
– supplying fresh air during rescue actions to places without ventilation; Fresh air can be conveyed within a distance even
of several dozens metres; The device can deliver fresh air for even 10 people.
Lightweight structure and quick-connectors for hose attachment make the device very easy in use.
High-pressure blower
Structure
The blower consists of a housing and a high-pressure turbine. The housing is equipped with a handle to carry the device
from one place to another. On the upper housing surface is located a motor switch to operate the turbine. The appliance is
equipped with a standard quick-connector to attach the hoses. The outlet air is warmed up by 35°C.
The blower is equipped with a five-metre-long power supply cable, ended with a plug.
Operational use
In application of room drying, PUT the blower outlet in distance of approx. twenty centimetres from the humid wall and
depending on the drying PROGRESS change the blower position. It is recommended that there is fresh air supply to the
dried room.
Provided that there is applied a flexible hose fastened through a quick-connector at the device outlet, the blower can be
placed in another room or outside the building. The hose tip can precisely remove humidity, even from the most inaccessible places. In larger rooms, it is recommended to apply several blowers DOG-1, whereby each of them is directed with
outlet to an another wall. For firefight hose drying, connect it through a quick-connector. If the DOG-1 blower is used for air
supplying to disastrously cut-off people (during the rescue action), connect through a quick-connector the firefight hose
or a flexible hose and place its outlet in a place allowing a free air access.

Application
The high-pressure blowers are used for conveying the air in conditions where is required high pressure or underpressure.
Blowers can be applied in industrial vacuum cleaners, filtering units of high underpressure, in aeration the water reservoirs
(sewage-treatment plants) as well as to create an “air geyser” in pools.
Structure
The blower consists of a housing, aluminium cast radial impeller, two silencers and a motor. The impeller is installed
directly on the motor shaft. Silencers are installed at the inlet and outlet. The device is adapted for work both in horizontal
and vertical position.
High-pressure blower
Conditions of use:
– admissible temperature of the intake air +40°C,
– The fan cannot convey viscous impurities and substances of explosion risk and of dustiness exceeding 0,3 g/m³.

The blower can be used in various areas: production halls, television and advertisement studios, utility rooms,
storehouses, etc.
Structure
Low-pressure blower
PODRYW consists of an axial fan mounted rotary in a framework. Due to this, the fan can be turned around the horizontal
axis and it can be fixed in the requested position. On the square housing is a rotation governor to switch on the fan and to
adjust the fan flow efficiency. The blower is equipped with a five-metre-long power supply cable, ended with a plug. Put
the blower outlet in a distance of 50 cm parallel to the wall. Drying proceeds due to high flow efficiency of the blower, but
at low pressure, therefore the drying effect is obtained by blowing off the close-to-wall layer only. Important is to provide
unrestricted fresh air to the dried room, by creating a natural air draught inside.
Due to low noise and small power consumption, the blower can work continuously, not being an inconvenience to surroundings.
