Axial fans

Klima Celje axial fans are produced depending on requirements and the installation, their diameter lying within the rage from 355 up to 1600 mm.  Klima Celje axial fans reach a performance of up to 200,000 m3/h  Higher pressures are achieved through a row joint with rotors opposed to each other.

Basic information

Dimensions  and scope of performance

Klima Celje axial fans are produced depending on requirements and the installation, their diameter lying within the rage from 315 up to 1600 mm.  Klima Celje axial fans reach a performance of up to 200,000 m3/h  Higher pressures are achieved through a row joint with rotors opposed to each other.

Housing

AV series axial fans housings are produced of corrosion resistant AL castings. There are two kinds of axial fans: those with a sliding guide for high pressure fans and those without it.  Turned-out flanges are placed on both ends of the housing, they have drillings for screws on the circle, which makes their mounting easier. The housing is typically painted as RAL 7040

Klima Celje offers a broad range of axial fans, including Ex-approved ones and smoke deflectors of a F300 and F400 class, marked as follows:

AVS -Axial fan to be positioned inside / outside within a working temperature up to 40°C.

A housing is produced of flat steel with flanges either welded upon, or shrank in. A rotor with AL-casting blades, an angle thereof is adjusted during the fan downtime. Balancing adjustment is checked statically and dynamically. All steel parts are painted / the housing is hot dip galvanized.

NAVV - Axial fan with a sliding guide blade to be positioned inside / outside within a working temperature up to 40°C.

A housing is produced of flat steel with flanges either welded upon, or shrank in. A rotor with AL-casting blades, an angle thereof is adjusted during the fan downtime. Balancing adjustment is checked statically and dynamically.  The sliding guide is welded. All steel parts are painted / the housing and the sliding guide are hot dip galvanized.

AVR -Reversible axial fan with to be positioned inside / outside within a working temperature up to 40°C.

A housing is produced of flat steel with flanges either welded upon, or shrank in. A rotor with AL-casting blades, an angle thereof is adjusted during the fan downtime. Balancing adjustment is checked statically and dynamically. All steel parts are painted / the housing is hot dip galvanized.

EX AV - Axial fan for use in an potentially explosive environment within a working temperature up to 40°C.

A housing is produced of flat steel with flanges either welded upon, or shrank in. A rotor with AL-casting blades, an angle thereof is adjusted during the fan downtime. Balancing adjustment is checked statically and dynamically. All steel parts are painted / the housing is hot dip galvanized.

EX AVV - Axial fan for use in an potentially explosive environment within a working temperature up to 40°C.   A housing is produced of flat steel with flanges either welded upon, or shrank in. A rotor with AL-casting blades, an angle thereof is adjusted during the fan downtime. Balancing adjustment is checked statically and dynamically. All steel parts are painted / the housing and the sliding guide are hot dip galvanized.

ODT AV - axial fan working as a smoke and heat remover for a declared temperature class (e.g., F400) according to EN 12101-3. To remove smoke and heat in case of fire and to ventilate under normal condition.  A housing is produced of flat steel with flanges either welded upon, or shrank in. A rotor with AL-casting blades, an angle thereof is adjusted during the fan downtime. Balancing adjustment is checked statically and dynamically. All steel parts are painted.

ODT AVV- axial fan working as a smoke and heat remover for a declared temperature class (e.g., F400) according to EN 12101-3. To remove exhaust gases and heat in case of fire and to ventilate under normal condition.  A housing is produced of flat steel with flanges either welded upon, or shrank in. A rotor with AL-casting blades, an angle thereof is adjusted during the fan downtime. Balancing adjustment is checked statically and dynamically. All steel parts are painted.

Rotor

Rotors, hubs and blades are made of die-cast aluminum. The aerodynamic blade profiles provide high efficiency and a possibly low noise level. During rotor downtimes, a smooth change of impinging angle of the blades is possible to be done.  Fans could be produced with different blade numbers which increases the efficiency.

Motor

Klima Celje uses alternating current motors which meet the IEC 34-1 Norm, EPACT version is possible as an option.  The motors are closed completely, cooled through the housing and all have a fault relay protection.  As a standard, they have IP55 protection level, class F acc. to ISO.  Sparkproof (Ex) motors with a higher protection level are available by the buyer request, as well as with a different number of poles for the motors with two or three rotation speeds.

Lay out and air flow direction

Axial fans of an AXV/BXV type could be easily mounted in various position.  Layout and possible air directions that are shown on the chart are standard ones and should be specified in the purchase order code.  If the order is placed with no data specified, a horizontally mounted fan version is supplied.

The air flow direction should be given obligatorily in case the fan is required with an engine compartment spray shield.  Arrows on the motor housing show the fan rotation direction and the air flow streamline.

Fan selection

Should the fan be chosen based on the characteristics, attention has to be paid to the fan curve selection (for a given blades impinging angle), the fan curve should rest over the required operation point, if possible within the middle part of the curve, i.e., when the fan is on its maximal efficiency.

Placing an order

The following important data should be given alongside with an order:

  • a sort of a housing, air flow streamline ant the installation layout
  • a distinct description of a fan which must be given in accordance with the type code
  • air stream delivery in m3/h and static stress of the fan in Pa with the air density at 1,2 kg/m3
  • the required motor power
  • voltage, frequency and number of phases of the electrical connection
  • required accessories

Assembly instructions

The principles described in “Assembly instructions” file should be observed during the assembly of the fan.
