Question 1

Do customers need to buy an air nozzle separately to inflate the balloon?

Accepted Answer

No need. Each canister of helium comes with a black balloon filling nozzle.

Question 2

Can all balloons filled with helium fly?

Accepted Answer

No. For a balloon to fly, two main factors must be met.
1. To fill the balloon with helium; 2. Balloon design (e.g., size, weight, mass).
 
Reference data:
Rubber balloons: 10" or larger
Aluminum film balloons: Star-shaped, heart-shaped, and round aluminum film balloons, 18 inches or larger. For other shapes, we recommend you consult a balloon shop. Letter balloons require a minimum size of 40 inches.
 
To ensure that the balloons you purchase will float after being filled with helium, we recommend that you check with the balloon supplier before purchasing to confirm whether the balloons are suitable for helium filling.

Question 3

How long can a balloon fly after being filled with helium?

Accepted Answer

The time a balloon floats is affected by the material and size.
International brand balloons use better materials, so they float longer. If your customer needs to display balloon decorations for an extended period, we recommend choosing [brand name - likely a brand name].
International Brands(http://www.balloonhk.com)
(Such as Quaratex, Sempertex, Anagram, etc.) Additionally, we recommend that guests inflate the balloons just before use; if inflated too early, the balloons may sink before the event ends.
 
We provide an approximate balloon float time (starting from inflation). If you require an absolute value, we recommend that you ask the balloon seller.
 
International Brands:
10-inch rubber balloon: 8-12 hours
12-inch rubber balloon: 10-14 hours
Rubber balloons 16 inches or larger: one day or more
18-inch or larger aluminum membrane balloons: 3 days or more
Japanese crystal balloons (https://www.balloonhk.com/categories/crystal): 5 days or more
 
Common brands:
10-inch rubber balloon: 4-8 hours
12-inch rubber balloon: 4-10 hours
Rubber balloons 16 inches or larger: 12 hours or more
18-inch or larger aluminum membrane balloons: 2 days or more
Non-Japanese crystal balloons: 1 day or more (obvious wrinkles will appear on the first day, while Japanese balloons generally take five days to develop wrinkles).

Question 4

How long can leftover helium be stored?

Accepted Answer

As long as the helium cylinder is tightly closed, the remaining helium can be stored for six months or more.

Question 5

Where should helium cylinders be stored?

Accepted Answer

Helium should be stored in a cool place, away from direct sunlight.

Question 6

Can helium be inhaled to create a voice-changing effect?

Accepted Answer

We do not recommend that guests use helium for voice changing. Although helium is a very safe gas, excessive inhalation of any gas can lead to oxygen deficiency/poisoning, and even death. Therefore, never release helium in enclosed spaces.

Question 7

Are there any precautions to take before and after inflation?

Accepted Answer

1. Connect and tighten the black inflation valve.
2. Please remember not to turn the switch all the way open, just turn it half a turn, to avoid the air coming out too quickly and possibly bursting the balloon.
Additionally: If you are not using it for an extended period of time, please remember to turn off the switch first, as the black inflation nozzle cannot completely prevent helium leakage, so as to avoid waste.

Question 8

How many air bubbles can a 36-inch rubber balloon hold?

Accepted Answer

Our 50-ball helium canisters can fill approximately 2-4 36-inch (90cm) rubber balloons, and our 70-ball helium canisters can fill approximately 3-6 balloons. The exact number depends on the shape of the balloon, the size of the balloon after inflation, and whether there was any helium leakage during the inflation process.
 
The 36-inch size refers to the maximum diameter the balloon can be inflated to. We do not recommend customers inflate the balloon to its maximum size. Reason:
Balloons are more likely to burst at their maximum size.
A balloon will deform at its largest size.
Balloons are generally inflated to a diameter of 60cm, which provides sufficient buoyancy and also achieves the optimal shape. Adding extra helium...
This results in waste.
 
If you would like to know the exact number of inflatable balloons, we recommend that you consult your balloon supplier for the optimal inflation size. This will allow us to calculate the number of balloons that can be inflated more accurately. However, since different brands of balloons have different inflation capacities and different levels of proficiency in handling helium canisters, we suggest that you prepare extra helium to avoid affecting the celebration.

Question 9

Why do some 22L helium tanks hold 50 balloons while others hold 70?

Accepted Answer

22L (22 liters) refers to the capacity of the helium tank, not the volume of helium gas inside. The actual volume of helium depends on the pressure inside the tank; the higher the pressure, the more helium gas is contained. Therefore, a 22L helium tank with 70 spheres has a higher pressure than a 50-sphere tank. Generally speaking, a 22L helium tank with 50 spheres has a pressure of 1.5-1.6 MPa, while a 70-sphere tank has a pressure of 2-2.2 MPa.
