the INW ring blower / vacuum pump
only according to the conditions specified by its parameters, which are
alsoavailable at www.in-eco.eu. This particularly concerns the ambient temperature and the sucked gas,
maximum pressure difference and level of electrical coverage.
Placement
Place the equipment in a well-ventilated area with sufficient air circulation.
For outdoor use, place the equip-
ment under a shelter, protecting it against unfavorable weather conditions (rain, snow, direct sunlight, etc.).
Prevent any liquids from entering the equipment. If the pipe to which the equipment is connected discharges
into liquid, place the equipment above the level of this liquid. If the equipment must be placed below this level,
prevent the reverse suction of liquid (for example, install a siphon on the pipe, install a backflow valve, etc.).
If the equipment (blower) is used in water treatment plant operation, place it accordingly to prevent it from
drawing in vapors from the water treatment plant, or from sucking in sludge or sludge foam.
Install the equipment in areas with sufficient space to enable its regular maintenance and necessary repairs.
The improper placement or installation can have a negative effect on the service life of the equipment.
Ventilation, cooling
Ventilation and cooling is essential for the proper operation of the equipment.
Leave at least 20 cm around
equipment placed indoors for natural cooling. When installing on a vertical wall, install the equipment at least
20 cm above the floor.
If necessary (for example, if you use the equipment in a small area or within a soundproof housing), ensure
the necessary air circulation (e.g. using a ventilator).
Air (gas) temperature and humidity
The INW ring blower / vacuum pump are designated for use in ambient temperatures ranging from -30°C to
+40°C. The optimal ambient operating temperature is 0°C to 25°C. When used in an environment with a tem-
perature exceeding 25°C, you must consider that the maximum pressure difference will be lower. About 10%
for a temperature of 40°C.
The maximum temperature of gas drawn in must not exceed 40°C.
The maximum humidity of gas drawn in must not exceed 80%.
Altitude
Air pressure (and humidity) drops with increasing altitude. According to the laws of physics, this affects the
blower/pump performance. If you intend to use the equipment at an altitude exceeding 1,000 meters above
sea level, consult the consequences with an authorized IN-ECO service center.
! Restrictions !
Do not use INW ring blowers / vacuum pumps for taking in steam, or gas that contains a high volume of dust,
charged particles, cellulose and particles larger than 40 μm.
Do not use INW ring blowers / vacuum pumps for compressing or pumping gases, which are explosive, flam-
mable, aggressive or poisonous.
Do not use INW ring blowers / vacuum pumps in areas where explosive gases may emerge.
Do not use INW ring blowers / vacuum pumps for taking in water or other liquids. Prevent any liquids from
entering INW blowers/pumps.

EMPERATURE OF DISCHARGE GASES
The compression of gas results in an increase in temperature. Temperature increases depending on the
pressure difference differ with each type of equipment. The curves of this dependency are available at
www.in-eco.eu. The following tables provide orientation values, separately for ring blowers and vacuum
pumps:
