Go Fan Yourself® was established in 2014 to address the shortcomings of conventional HVLS fans in the industry. To truly be different and be cool, we needed to design and manufacture our own products. This allowed GFY® to be proactive at the highest level and create solutions for inherent gaps in conventional HVLS fan design that our customers had brought to our attention.
Four major problem and opportunity areas surfaced that our revolutionary Z Tech™ technology addresses.
Challenge #1: Limited Coverage of Conventional HVLS Fans
The predicted and limited air flow coverage of conventional HVLS fans.
- Conventional HVLS fans (spanning 6-24’ typically) are designed around an air foil concept, much like an airplane wing. The concept is to push air down. This enables air movement, which can have a measurable impact on air quality in a given space, however, coverage is limited and conventional HVLS fans do not provide even air distribution.
- Company’s capital expenditures are often limited to the number of fans that are purchased and installed - thus leaving workers in other areas on a warehouse or manufacturing floor uncomfortable (either too hot or too chilly from a conventional HVLS fan) and therefore less productive.
The patent-pending Z-Tech™ blade. This stepped, symmetrical Z blade dramatically reduces frictional air resistance and drag. The stepped blades stay in contact with the air - greatly increasing displacement and thrust while naturally generating more air flow below.
- The patented Z-Technology stepping of the blades is an enhanced form of venting and venting creates better air displacement.
- The stepped blade design allows the velocity of air flow to move past the steps, at which point the pressure immediately decreases and that allows for a significant increase in air movement.
- Up to 30% increase in area coverage versus conventional HVLS Fans
- Reduces the number of fans needed, keeping costs in line with the facility budget
- Enables a safe, comfortable and productive work environment
- Moves air at 425,000 cubic feet per minute
- 1 cubic foot of air weighs 0.08lb
- Equates to 34,000 lbs. of air moving through the fan blades every minute
Challenge #2: Dead Zone
Addressing the dead zone area which is the area directly under the center of a conventional HVLS fan.
- Conventional HVLS fans utilize a flat diameter plate for the design of the hub so when the fan spins, the hub creates the “eye of the hurricane” effect and there is no air flow or air movement directly under the fan spanning a noticeable circumference.
- People would complain about having to work in the dead zone area as this air would remain stagnant while others who were working a few feet out from directly under the fan would feel the fans cooling benefits.
The Z-Tech™ HVLS Fan is built with a pitched hub that has the same 20° plus contour as the pitch of our blade.
- This design enables the hub to act as an extension of the fan - eliminating the dead zone.
- Air movement is felt with more uniformity - even airflow distribution.
Challenge #3: Effective Destratification
People tend to shut off the conventional HVLS fans off in the winter months defeating the purpose of destratifying the air.
One of the primary reasons customers purchased conventional HVLS fans was to significantly reduce heating costs within the facility through destratification (the non-layering – or mixing of air – as warm air rises, cool air falls) by having the fan slowly push the warm air hovering at the ceiling back down into the work space below.
- Conventional HVLS fans utilize an air foil designed to run in forward rotation so employees would become uncomfortable due to the wind chill being created by the air being pushed downward.
- Utilizing a HVLS fan in forward rotation can leave warm air trapped at the ceiling as the air is drawn in from the sides of the fan rather than the air above the fan.
- Consequently, the people working in the area where the fan was installed would typically walk over to the fan’s control box and turn the fan off eliminating any potential energy savings resulting in a higher electric bill.
The Z-Tech™ HVLS Fan was purposely designed with a symmetrical blade to run in reverse rotation during winter months, when air destratification is needed.
Z-Tech™ pushes air up and mixes the air to eliminate any type of wind or air movement chill.
- Eliminates wind chill effect
- Designed to stay on in the cooler months
- Increases employee comfort and productivity working within range of the fan
- Decreases energy heating costs
Challenge #4: Temperatures Above 90 Degrees
HVLS fans have been utilized in facilities to provide massive air movement at low speeds as a cost effective and energy efficient solution to help provide comfort.
However, during the high heat of summer and when the heat index soars above 90 degrees, the air becomes too warm for the fans to be able to provide any type of evaporative cooling, therefore, they are just blowing around hot air.
This leads to the fans being turned off by people working in the area below and within range of the fan as the fans were not providing the much needed tempered breeze to provide enough comfort and relief – in contrast with effect of stagnant heat – desired in stifling summer months and or due to heat-producing manufacturing production processes.
At these elevated temps, the concept of the HVLS fan providing evaporative cooling is not applicable.
The Revolutionary Z-Chill™ System. Go Fan Yourself® is pioneering new technology with Z-Chill™ and altering the HVLS fan industry forever.
The Z-Chill™ system is a breakthrough, patent-pending system designed to effectively spot cool the unconditioned space within a facility by distributing tempered air and provide companies an economical tempered cooling solution to keep business operating at their highest level.
The innovative Z-Chill™ system starts by utilizing the patented Z-Tech ™ fan design to get the maximum amount of area coverage - complete with no dead zone. The patent pending Z-Chill ™ dispenser unit is incorporated onto the Z-Tech™ fan to create a revolutionary system that will change work spaces around the world.
- Facilities will finally be able to truly address potential issues by providing tempered spot cooling to selected areas without cooling the entire space with an expensive, cost-prohibitive HVAC system.
- Decrease Heat Stress/Stroke
- Decrease Productivity Losses
- Decrease Absenteeism
- Increase Employee Retention
- Increase Creature Comfort
