AIRFOIL BLADED FANS
CLEAN GAS OR GAS WITH NON-ABRASIVE
AND ONLY SLIGHTLY CLOGGING DUST
Because of the aircraft wing profile shape of the blades, the fluid is discharged with
a minimum of turbulence, shocks and loss in the impeller, with as a result silent
operation, low input power and a high efficiency.
As each blade forms a box beam which can be stiffened on the inside, a airfoil
bladed impeller is mechanically very strong and allows for very high operating
speeds.
This blade is particularly well suited for wide impellers both from an aeraulic
and mechanical point of view.
This blade is generally used for clean gas but is also suitable for gas charged
with dust even if clogging, except for the C14 family.
It is not suitable for gas charged with abrasive dust.
|
|
BACKWARD INCLINED FORWARD
CURVED BLADED FANS
GAS CHARGED WITH CLOGGING
OR ABRASIVE DUST
The shape of these blades is designed so as to minimise the risks of clogging. Through its curve to the front it prevents dust sticking onto the lower side of the blade.The blade tip is very turned up or even radial for the narrow families, which among other things gives it high manometric capacity.
This blade is particularly well suited to thick anti-corrosion-resistant coatings such as ebonite.
Another advantage of this blade is its good mechanical resistance which means
that it can be used at a high temperature.
The curved shape of the flare, the inlet disc and the blades provide a good flow
of the fluid in the impeller and means that efficiency and noise levels which are
significantly better than conventional radial blades can be obtained.
|
|
BACKWARD INCLINED
BLADED FANS
GAS CHARGED WITH ABRASIVE
OF SLIGHTLY CLOGGING DUST
The flat shape of the blades facilitates cleaning of the impeller and also its protection by wear plates.
The wear takes place in a well-defined zone (blade trailing edge against the back disc) which provides the means for effective protection of the impeller by wear plates and/or hard metal coating.
The blade's incline to the rear provides for good efficiency and low noise levels
to be obtained.

The K-Box ventilators are duct type ventilators used in kitchens, restaurants, bars and canteens due to their specific construction.
Isolation of electric motor area from the rotor area enables using the K-Box ventilator in extreme conditions with humidity up to 95% RH and temperature range of -15°C to +100°C.
Condensation and oily vapours do not interfere in proper operation of the ventilator and during the operation a tray under the rotor allows maintaining hygiene for all kinds of impurities.
A wide performance scope ranging from 4 100 to 15 500 m³/h allows for selecting a ventilator suiting any needs.
A modular construction of side walls made of galvanized sheets filled with a polyurethane core and an aluminium profile structure make flexible application to understand individual needs.

Tornado II roof ventilators are intended for use in ventilating areas of large cubic capacity like warehouses, halls, etc. A large performance scope ranging from 1000 to 12 100 m3/h makes it easy to select a ventilator to suit any client.
The ventilator body is made of a polyester and glass composite. The body is coated with gel-coat layer, which increases its durability and make resistant to mechanical and chemical factors. It also protects the product from moisture and the negative effect of sunlight.
Owing to the high quality of materials used for manufacturing the body, the element in fact does not require painting, and the period of operation does not affect the intensity and durability of the pigment used.
The standard colour of the ventilator is navy blue (RAL 5011), however, it is possible to paint it according to the customer's requirements within the RAL palette.

WDD roof ventilators belong to the industrial ventilator group, and due to its specific construction, it is classified as centrifugal fans with vertical air exhaust.
WDD ventilators may be installed on roofs where because of space shortage the exhaust is near the fan. Vertical dumping of the air minimises the risk of intaking used air back into the rooms.
The construction of the ventilator is made of galvanized steel sheets, and the body and the element protecting the electric motor from rain and snow is made of aluminium sheets.
The flow capacity ranges from 1 700 to 16 000 m³/h.

MF Series Cross Flow Fans (8)
Cross flow fans create a wide flow of air using a long cylindrical-shaped impeller. Air is drawn inn along the sides of the runner, flows along the circumference of the runner, and is blown out laterally, creating a uniform flow of air. Cross flow fans are used for cooling circuit boards installed in equipment, air curtains, and other applications. In addition, cross flow fans offer the advantages of right-angle air flow and rectangular shape which facilitates installation in corners and saves space.
