HIGH VOLUME. The RobovenT blade : high volume, low speed fans The RoboVent Blade, a high volume, low speed fan, is changing the way industrial and commercial buildings are ventilated. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed." Unlike a small, high-velocity fan that creates small, turbulent air streams that quickly disperse, an HVLS fan relies on size, not speed, to move a significant amount of air. Ceiling fans circulate air at low speed and high volume. HVLS Fans - Big ceiling fans are durable, cost-effective and provide massive air movement in industrial and commercial spaces. Spal 30102048 Pusher Fan 16In High Performance, Curved Blade - 1959 cfm. The air loses friction with the blade almost immediately in this flat blade configuration. How the High Volume Fan Works. NPFA 13 Requirements for HVLS Fans NFPA 13 defines high volume low speed fans as ceiling fans approximately 6 feet (1.8 m) to 24 feet (7.3 m) in diameter, with a rotational speed of approximately 30 to 70 revolutions per minute (NFPA 13 2013-16 Section 3.3.14). Senior Application Engineer Chet White demonstrates the high-efficiency backward curved fan in this 30-second video. Single-axis mount ensures solid placement and reduced movement. When specifying this type of fan, airflow volume is a big factor. Blower Fans. The custom-molded blades are designed for high-volume air delivery with less noise and turbulence than typical case fans. connect with one of our application engineers, It’s in the Baghouse: Fan Efficiency for Dust Collectors, Founders’ Message: Quality of Work, Quality of Life, Stainless Steel Fan for Protein Rendering. Condenser fan blades are used to replace worn or damaged blades in HVAC condensers. Large and long blades combined with a high number of blades may lead to the fan spinning slowly although moving an amazing amount of air, while the shorter and few blades may increase the spin of the fan thus high RPM. DC Backward Curved Motorized Impellers Your company account is blocked and you cannot place orders. Save $10 off $299, $20 off $599, $30 off $799, $100 off $1,599 Orders We have Super Hard PAG Blades, 3-, 4- and 6-blade poly fan blades, and galvanized and aluminum replacement blades. Plastic fan blades are lightweight and corrosion resistant for use in harsh environments. To handle high volumes at low static pressures, you may opt for a single or double width blade model. really, there’s documented proof – and we want to share it with you. A fan blade will often rotate when exposed to an air-fluid stream, and devices that take advantage of this, such as anemometers and wind turbines , often have designs similar to that of a fan. Open 24x7 - Same Day Shipping! Mechatronics High Airflow Fans are ideal for applications where space is limited and high airflow is required. Multi-Wing America’s airfoil impellers provide uniform, high volume airflow with low power consumption for optimum efficiency using the same aerodynamics that create flight. 5 out of 5 stars (3) 3 product ratings - Spal 30102048 Pusher Fan 16In High Performance, Curved Blade - 1959 cfm. Corsair Air Series LED high airflow PC case fans combine efficient, low-noise airflow with striking LED lighting. Made of high quality materials for long lasting durability and dependability. It’s rated for damp locations, but should not be in an area where it will get wet directly. When you’re ready to start your project, reach out and connect with one of our application engineers to discuss the details of your specification. Fig 2shows the pressures through a fan, each of which is described below: Inlet Pressure; is the static pressure on the inlet side of the fan. Typical applications for HVLS fans fall into two classifications—industrial and commercial. Here, we’re taking a close look at the backward inclined high volume fan. Very similar to the backward curved fan, the wheel can rotate in the direction best-suited for your application, with the air entering in the middle of the wheel, hitting the hub, and then coming out along the travel of the blade. Available in 12/24/48vdc models in sizes ranging from 30mm-120mm. Standard and Q-style Multifan replacement blades, AP Performer … Free Ground Shipping on Select Modine Heaters. They don’t just look cool, they deliver top efficiency to heating and cooling systems by reducing their run time, cycles and improving overall occupant comfort and morale…. 18 watching. for pricing and availability. This is the fan that started the HVLS revolution. The 12 hour programmable timer and remote control will provide you with more convenience. Coming down a bit more in CFM rating, but still considered high, the Fanimation Xeno holds a 7,782 CFM rating. Replace old rusty fan blades with high-performance replacement blades.

Condenser propeller hubs connect the fan blade to the motor drive shaft. SkyBlade Fans High Volume Low Speed (HVLS) Fans are specially designed to move more air at lower operating speeds. Fanimation Studio Collection Slinger v2 72-in Matte black LED Indoor/Outdoor Ceiling Fan with Remote (9-Blade) Item #795392. Provide efficient air cooling and circulation for warehouses, dock doors, receiving bays, and more. Get a replacement propeller to rebuild your air circulator instead of buying a new unit, or buy a spare condenser fan blade to make sure you have all the parts you need to minimize service outages. CalQlata has tried to keep the operation of this calculation option as simple as possible, given that it is recommended for general purpose calculations only and not for actual purchase specifications (see Fan Calculator – Technical Helpbelow). The typical industrial high-volume low-speed fan system is 20 feet or 24 feet in diameter. A double width blade allows you to increase your air volume capacity without increasing the wheel diameter.
