An Industrial Axial Fan is a mechanical device designed to move air or gas along the axis of the fan. It operates by drawing air in parallel to the fan shaft and pushing it out in the same direction, producing a high volume of airflow.

Key Characteristics:

• Airflow Direction: Axial, meaning air moves straight through the fan along the axis of the rotating blades.

• Design: Typically features a set of blades (often 3 to 8) attached to a central hub, mounted on a motor shaft.

• Material: Can be made from materials like steel, aluminum, or composites, depending on the application and environmental requirements.

• Sizes: Available in various sizes, from small ventilation fans to large industrial units capable of moving thousands of cubic feet per minute (CFM).

• Mounting: Can be installed in walls, ducts, or as free-standing units, depending on ventilation needs.

Applications:

• Ventilation in factories and workshops

• Cooling for industrial machinery and processes

• Exhaust systems for fumes, smoke, and dust

• HVAC systems in large buildings

• Tunnel ventilation

• Agricultural ventilation (barns, greenhouses)

Advantages:

• High airflow capacity suitable for large spaces

• Simple and robust design, easy to maintain

• Can handle high temperatures and harsh environments (with proper materials)

• Cost-effective for general industrial ventilation

• Suitable for both intake and exhaust purposes

A Jet Fan is a type of axial flow fan commonly used for ventilation in confined spaces such as tunnels, underground car parks, and large enclosed areas. It is specifically designed to move large volumes of air efficiently to control air quality, remove smoke, and maintain safe environments.

Material:
The fan casing and blades are made of mild steel, a versatile and cost-effective type of carbon steel known for its strength, durability, and ease of fabrication. Mild steel offers good resistance to mechanical stresses and can be coated or painted for enhanced corrosion resistance.

Design Features:

• Compact and Streamlined: Designed to be installed on ceilings or walls, saving space and reducing installation complexity.

• High Velocity Airflow: Generates powerful airflow jets to effectively ventilate large spaces or long tunnels by creating directional airflow.

• Durability: Mild steel construction ensures robustness, suitable for industrial environments.

• Coating: Often powder-coated or galvanized to protect against rust and environmental damage.

• Noise Levels: Engineered to minimize operational noise for a comfortable environment.

Applications:

• Tunnel ventilation

• Underground parking ventilation

• Emergency smoke extraction

• Industrial ventilation systems

Advantages:

• Cost-effective compared to stainless steel or aluminum fans

• Strong and durable for heavy-duty applications

A Cassette Type Fan (often called a Ceiling Cassette Fan or Fan Coil Unit - Cassette Type) is a ceiling-mounted air distribution unit, commonly used in commercial HVAC systems. These fans are integrated into ceiling tiles and deliver conditioned air evenly across a room, typically as part of ductless split or VRF (Variable Refrigerant Flow) systems.

• Remote Control Operation: Often equipped with wired or wireless remotes and smart system integration.

• Multiple Fan Speeds: Adjustable to match occupancy and comfort levels.

Explosion-proof fans are specially designed ventilation or exhaust fans built to operate safely in hazardous environments where flammable gases, vapors, dust, or fibers may be present. These fans are constructed to prevent ignition of surrounding explosive atmospheres, either through spark-proof design, intrinsically safe components, or enclosure protection.

They are essential for complying with safety standards like ATEX, IECEx, or NFPA in industries where explosive atmospheres are a known risk.

• Spark-Proof Construction: Non-sparking materials (e.g., aluminum, bronze, or coated steel) are used for fan blades, motor mounts, and other components.

• Explosion-Protected Motors: Motors are sealed in explosion-proof housings to prevent ignition of external gases or dust.

• Certified Enclosures: Fan components are housed in enclosures rated for hazardous zones (e.g., ATEX Zone 1, Zone 2, Class I Div 1, etc.).

• Corrosion-Resistant Materials: Often made with stainless steel or coated metals for use in corrosive or chemical-rich environments.

• Grounding/Bonding: Electrical grounding to prevent static discharge.

• Low Heat Operation: Designed to minimize temperature rise and eliminate hot surfaces.

The KAT series is DIDW centrifugal fan with forward curved (FC) impellers. The fans are suitable for supply and exhaust applications in commercial, process and industrial HVAC systems. Ranges KAT-9/7 to KAT 18-18 are AMCA certified to Air, Sound and FEG.

The KAT series is available in Type S and C.

KAT series is also available in twin fan version with two double inlet fans mounted on the same shaft.

KAT fans are operated at relatively low speeds and are used to deliver large air volumes against relatively low static pressures. The inherently light construction of the forward curved wheel does not permit it to be operated at speeds needed to generate high static pressure.

The typical application range of this type of fan is from 30 to 80% wide open airflow. Selecting an operating point below approximately 30% wide open may place the fan in an area of instability. Similarly, an operating point beyond 80% wide open typically produces noise and inefficiency.

The maximum static efficiency is from approximately 50 to 65% and occurs just to the right of the maximum static-pressure point on the fan performance curve.Quick Facts

The BNC series is a backward curved plenum fan.

The full range of BNC series is AMCA certified to Air, Sound and FEG.

Plenum fans are designed for air handling application where the fan wheel operates without a housing. It operates inside a plenum. This results in saving of space normally occupied by the fan housing, transition and diffusers. The fan wheel pressurizes the entire plenum in which the fan is installed. The allows air ducts to be directly connected from any direction of the plenum. The compact size of the plenum fan makes it an excellent selection for retrofit and replacement application and for variable air volume systems.

There are three types of the BNC series, i.e. BNC-R (regular type), BNC-P (high pressure type), and BNC-Q (high volume ratio type).
