Supply and Exhaust Fans

Types of Exhaust Fans:

⇒ Wall Propeller Fans: Efficient & Versatile Solutions

Wall propeller fans are an excellent general ventilation solution, designed for both commercial and industrial environments, such as warehouses, schools, hospitals, and wastewater treatment plants. These fans offer durability, efficiency, and flexibility, with both belt-drive and direct-drive models available:

• Belt-Drive Models: Available in 18” to 84” sizes, offering quieter operation and lower initial cost.
• Direct-Drive Models: Available in 7” to 70” sizes, featuring lower maintenance requirements, longer lifespan, increased efficiency, and reduced operational costs.
• Many belt-drive models include a variable pitch motor pulley, allowing for adjustable fan speeds to control airflow.

Optional accessories include inlet hoods, discharge hoods, and mounting flanges, ensuring a balanced and efficient air-moving system.

⇒ Upblast Rooftop Exhaust Fans: Powerful Ventilation for Industrial Spaces

Upblast rooftop exhaust fans provide long-lasting, low-maintenance ventilation in industrial environments. These fans discharge air vertically, using air velocity to create a natural seal against rain and snow.

Upblast exhaust fans are ideal for:

• Removing smoke and heat in compliance with building codes for shopping centers, warehouses, and hotels.
• Industrial service environments where the fan assembly must be roof-mounted.
• Fire safety applications, ensuring efficient removal of combustion by-products.
• Hard-to-reach installations, reducing the need for frequent maintenance.
• Harsh environments where heat and air contaminants are prevalent.

Available accessories include safety disconnect switches, roof curbs, damper doors, automatic heat and smoke venting, spark-resistant construction, and protective coatings.

⇒ High-Velocity Supply Units (HVSUs): Targeted Airflow for Specific Areas

HVSUs are air handling units designed to supply high-velocity airflow to targeted zones within a building. Typically installed in walls, these units deliver fresh air at high speeds to efficiently distribute heating, cooling, or ventilation throughout a facility.

HVSUs come equipped with essential components such as wall housings, supply dampers, bird screens, and rain deflector hoods to ensure optimal performance and protection.

Best Practices for Fan Placement

Strategic fan placement ensures optimal air turnover, velocity, and even distribution throughout a facility:

✔️ Position exhaust fans on the opposite wall of a loading dock door and run them only when the door is open.
✔️ If no dock door is available, install supply fans on the north side of the building to avoid pulling in heat from direct sunlight.
✔️ Use roof exhausters alongside supply fans to remove hot air, fumes, and vapor effectively.
✔️ For heat-generating machinery, place a roof exhauster directly above to dispel heat while also ventilating the entire facility through supply and exhaust fans.
