When it comes to creating a visually stunning and dynamic stage show, haze machines can be a powerful tool. But where should you place them for optimal performance? One option is to place the haze machines high in the air. But what are the pros and cons of this approach?

Haze machines are more effective when placed in the air for several reasons:

1. Greater dispersion: When a haze machine is placed high in the air, the haze is more dispersed and can cover a larger area. This can be beneficial for large venues or outdoor events, where the haze can be seen from a distance and create a more dramatic and spectacular display.
2. Greater duration: Haze machines produce a fine mist of mineral oil or water-based fluid that hangs in the air for a longer time than fog, allowing the audience to see the light beams and laser effects for a longer duration.
3. Greater visibility of lighting effects: Haze machines are often used in conjunction with lighting effects, such as stage lighting or laser shows. When haze is present in the air, it allows the light beams to be seen more clearly, creating a more dramatic and spectacular display.
4. Greater control: Haze machines can be placed in specific areas and controlled to create a desired effect. This allows the technician to control the amount of haze and its location, giving them greater control over the final output.

However, there are also some drawbacks to placing a haze machine high in the air:

1. Wind Direction: If the wind is blowing in the opposite direction of the machine, the haze will be blown away from the intended area, reducing the output.
2. Fluid Refill: It can be more difficult and time-consuming to replace the fluids. This is because the machine must be refilled manually using a ladder or aerial lift, which can be dangerous, labor-intensive, and expensive.
3. Maintenance: Placing a haze machine high in the air can make maintenance more difficult, as it may require scaffolding or special equipment to access the machine. Additionally, it can be challenging to refill the machine with fluid, which may require the use of an automatic refilling machine such as the EFR Reservoir.
4. Safety: Placing a haze machine high in the air can pose safety risks, as it may require workers to climb to high elevations to access the machine. This can increase the risk of falls or other accidents.

An automatic refilling machine, such as the EFR Reservoir, can alleviate the problem of fluid refill by automatically transferring fluids to high places. However, it is important to note that the EFR Reservoir’s effectiveness is still dependent on factors such as fluid type, ambient temperature, and tubing inside diameter, among others. So it is best to account for all variables when planning your setup.

In conclusion, placing a haze machine high in the air can be a powerful way to create a visually stunning and dynamic stage show. However, it is important to weigh the pros and cons and consider the specific needs and constraints of your event or performance. The EFR Reservoir is a great solution to the problem of replacing fluids, but it's important to consider all possible variables.
