Custom Exhaust Fan

The custom exhaust fan option reduces operating and maintenance costs at the same time and has a smaller footprint.

The new ductwork transition needed to go from your (custom fan) fan array minimal (if any is required). Exhaust for custom fans can be configured to go any direction.

The new custom exhaust system will have CFM redundancy and can be controlled using an optional digital controller.

• Energy savings.
• Maintenance free.
• Lower running costs.
• More efficient and quieter than traditional belt driven fans.
• Multiple exhaust directions are possible and can easily be configured to meet any customer need or requirement.

These fans can be used in-line with existing duct work for supply and exhaust applications. They produce superior CFM output at lower amperages (lower running costs) and are more efficient and quieter than traditional belt drive fans. They can provide static pressure up to 2in wg (1,000 Pa) with flow capacities up to 9,000 CFM (15,291 m3/hr). These fans can be installed horizontally, vertically, or at any angle required to mate up with existing ductwork. Exhaust options includes left, right, top, bottom and front sides. Multiple exhaust directions are possible with the BKL-EZA direct drive fan and can easily be configured to meet any customer need or requirement.

Baikal Mechanical fans consist of single inlet, backwards-curved, high efficiency impellers made of high strength ZAmid composite material. ZAmid is microbially inert and is suitable for stricter hygiene requirements as well as clean rooms. The impellers have been designed and optimized using computational fluid dynamics (CFD) to maximize airflow output. The fan inlet cone is airflow optimized and equipped with an air volume measuring system (pressure sensing ring). The fan is driven by an electronically commutated motor (EC-Motor) with external rotor and integrated electronics. The integration of the electronics in the motor allows a simple connection of the power and control lines. The fan consists of a motor-impeller with installed inlet cone and electronic control unit (ECU). The motor is manufactured with maintenance-free ball bearings both side closed with long-term lubrication.

EXHAUST FAN CONSTRUCTION FEATURES

• Fan housings are constructed of aluminum. (Stainless steel construction is optional for all model sizes).
• All fan housings are powder coated which prevents rust and adds to aesthetic appearance.
• Maintenance and service door provides easy access to fan, variable speed control, and power wiring.
• Discharge can be configured in any direction per application. (ex: left, right, top, or mushroom style).
• Direct drive EC motor provides efficient transfer of power to fan.
• Fan operates quieter than traditional direct drive fans due less friction and moving components.
• Manual variable speed control is included on all models and allows for the adjustment of air flow for system balancing.
• All wiring and electronics are NEC compliant and UL certified.

If you’ve ever been to a sweaty gym, a stinky toilet, or a hot kitchen; then surely you can appreciate the value of an exhaust fan. It is the most common and most widely used HVAC equipment.

Exhaust fans suck out the stale indoor air of a room and replaces it with fresh air from the outside. They are essential for maintaining the room’s air quality and temperature, letting out bad air, and improving ventilation.

What Exactly is an Exhaust Fan?

Whether they are residential or industrial wall exhaust fans or residential or industrial roof exhaust fans; they have the same function. These are fans that pull bad (i.e. stale, dirty, hot, moist, or hazardous) air out of a room or a building and pulling good (i.e. fresh, cool) air in.

The job of an exhaust fan is to reduce moisture and eliminate odors in enclosed areas like gyms, toilets, kitchens, restaurants, shops, manufacturing floors, other commercial buildings, and residential facilities. It also helps reduce fume buildup and removes contaminants that may cause harm when breathed in.

How Do Exhaust Fans Work?

They are not unlike any other fan you have in your house; however, they operate in a different way. The simple three-step process includes:

1. The fan’s motor operates the blades which pull bad indoor air out of the room.
2. The fan passes the bad air through facility’s ductwork and expels it out through a vent.
3. The fan allows fresh outside air into the room.

These fans use electricity and can be operated using a wall switch.

Commercial Exhaust Fans Vs. Industrial Exhaust Fans

Different spaces need different types of ventilation. Commercial exhaust fans are used for businesses, offices, stores, and other commercial areas. On the other hand, industrial exhaust fans are used for industrial spaces like factories, plants, and other industrial facilities.

There are two types of exhaust fans for industrial use. They are industrial roof mounted exhaust fans and industrial wall mounted exhaust fans. Commercial fans also come in these two types.

Whether your space is commercial or industrial; you need to get rid of stale and contaminated air to make room for fresh and clean air. Exhaust fans are the perfect solution.

The Benefits of Exhaust Fans

The advantages of using an exhaust fan cannot be overstated. They improve the air quality as well as the comfort and health of the occupants. Here are just some of the many benefits:

• They can quickly cool areas down; especially after heat-inducing activities like showering, exercising, cooking, etc. Even without air conditioning, these fans can reduce the temperature of the room.
• They remove excess moisture that can damage a building. When hot water condenses, there is moisture buildup on the ceilings, the walls, as well as other surfaces. This could lead to mold and mildew growth.
• They improve the quality of indoor air by removing humidity, unwanted particles, contaminants, moisture, and odors; and providing adequate ventilation.

Exhaust Fan Technical Specifications

Exhaust fans are made of the following components:

• Air intake valve
• Ducts – They are used to move the air from Point A to B.
• Air cleaning or filtration device
• Fans – They suck out the bad indoor air and bring in the fresh outdoor air.
• Discharge stacks

Application of Exhaust Fans

Because of its ability to effectively perform the functions discussed above, exhaust fans have a wide variety of applications in both commercial and industrial facilities. These fans are commonly used in hospitals, schools, restaurants, manufacturing plants, warehouses, workshops, kitchens, garages, and pretty much any commercial and industrial space. Additionally, many residential spaces have also embraced these versatile and efficient fans.

If you wish to efficiently pull bad air out of any space to invite good air in, improve the air quality of your indoor space, and improve the comfort of the space’s occupants; then an exhaust fan is an investment you must make.
