40 cu ft Helium Balloon Kit – Helium Cylinder + Balloon Filler Valve

When you’re ready to step up to a greater helium capacity and do a bunch more balloons, the 40 cuft helium balloon kit is the right move.

This helium balloon kit includes our midsize 40 cubic foot helium tank plus Western Enterprises’ high-quality balloon filler valve/regulator at a discount price.

Not only will this kit fill over a hundred balloons, it lets you stop the endless “buy another helium tank” cycle. Our tanks are industrial-quality, high-performance cylinders that can be filled over and over again. You’ll buy this once, and you’re set for as many parties as you’ll ever have. It will practically pay for itself.

All cylinders ship empty. Please consult your local compressed gas supplier for filling needs.

Deluxe Latex Inflator / Balloon Filler Valve

The kit includes a premium latex inflator/filler valve and regulator. This unit is one of Western Enterprises’ best and most versatile regulators, capable of providing 38-85 PSI of helium through its rubber tip tilt valve. It handles large and small balloons with ease.


How Many Balloons Can This Cylinder Fill?

  • Balloon size, gas waste, temperature, and other things play a role when figuring how many balloons a cylinder can fill. There’s no one-size-fits-all answer, but we can provide an estimate.
  • Party supply stores large tanks hold 14.9 cu ft of helium and fill about 50 9″ latex balloons, while their small pre-filled cylinders hold about 8.9 cu ft of helium and fill about 30 9″ latex balloons. That works out to around 3.3 balloons per cubic foot of helium.
  • Our smallest tank fills more than their largest, and our largest fills four times as many balloons!

This 40 cu ft helium balloon kit will fill approximately 133 9″ balloons

Please note: all cylinders ship empty.

Gas Cylinder Source knows you need your product now, which is why we offer super-fast shipping and even have an express option. We also recognize shipping charges can play a significant role in a purchase, and that is why we do everything we can to keep shipping rates as low as possible. We do not inflate the price of our products as a mask for free shipping offers. Our product prices are set at the best pricing we can offer, and the amount charged for shipping covers the shipping and delivery of your order. We believe this transparency in costs is the best way to keep you well-informed while receiving the best price available.

Calculate Your Shipping
You can calculate your shipping charge in just a few quick steps:

  • Add your desired product(s) to the shopping cart.
  • Navigate to the Shopping Cart page.
  • Click the "Calculate Shipping" link in the cart totals section and enter your Country, State, City, & Zip Code, then select the 'Update' button.

Residential vs Commercial Address
Initial shipping charges calculated in the Shopping Cart are figured using a residential shipping rate unless you have previously entered a commercial address in the ship-to field during a previous checkout session. Deliveries to a commercial address are typically cheaper than deliveries to a residential address and will be reflected on the checkout page once the full address has been entered and the system confirms it is a commercial address.

LTL Freight Shipments
For larger freight or custom orders, we ask you to allow for a 7-10 business day lead time for product preparation and shipping set up. A customer service representative may reach out to you requesting additional information such as liftgate needs, receiving hours, or other order details. Once your order has shipped, you will receive tracking information. LTL Freight Costs will be calculated on the day of shipment and may vary from your initial estimate, resulting in additional charges.

Time to Ship
Product is shipped from Minnesota. Transport time is usually between 1 and 5 days. Orders typically ship out the following business day after the order has been placed. Larger orders, and especially those going via a contracted freight service, may take additional time.

Order Tracking
Once your order has been shipped, an email will be sent to you with tracking details as well as a link you can use to track your shipment and find estimated delivery information.
