What Is FastGas? The Complete UK Guide to 580g & 640g N2O Tanks

Table of Contents
If you’ve searched for cream chargers in the UK, you’ve almost certainly come across the name FastGas. It appears on forums, catering supply lists, and professional kitchen equipment sites — but the product itself isn’t always clearly explained. This guide covers everything: what FastGas is, how it works, which size to buy, and whether it’s right for your setup.
FastGas is a brand of large-format N2O (nitrous oxide) canisters, available in 580g and 640g sizes. One FastGas 640g cylinder contains the equivalent of approximately 80 standard 8g cream chargers — making it significantly more cost-effective for high-volume catering, professional kitchens, and frequent home use. It is 100% food-grade and legal for culinary use in the UK.
What Is FastGas?
FastGas is a brand of professional-grade nitrous oxide (N2O) canisters designed for use with cream whippers and dispensers. Unlike the small 8g steel cartridges most people are familiar with, FastGas comes in large pressurised aluminium cylinders — typically 580g or 640g — that connect to your dispenser via a regulator.
The gas inside is identical to what’s in standard 8g cream chargers: food-grade N2O, the same gas used in professional kitchens worldwide to whip cream, create espumas, infuse spirits, and produce culinary foams. FastGas simply delivers it in a much larger, more economical format.
The brand is particularly popular with:
- Restaurants and fine dining kitchens
- Cafés and coffee shops with high cream output
- Event caterers and hospitality businesses
- Home users who go through chargers quickly
FastGas Sizes: 580g vs 640g
FastGas comes in two main sizes in the UK. Here’s how they compare:
| Feature | FastGas 580g | FastGas 640g |
|---|---|---|
| N2O content | 580g | 640g |
| Equivalent 8g chargers | ~72 chargers | ~80 chargers |
| Best for | Regular home use, small cafés | Professional kitchens, high-volume catering |
| Regulator required | Yes | Yes |
| Cost per litre of N2O | Significantly lower than 8g | Lowest cost per litre |
For most professional applications, the 640g FastGas cylinder offers the best value — the higher N2O volume means a lower cost per serving, and the larger tank means fewer changeovers during a busy service.
FastGas vs 8g Cream Chargers
The most common question is whether to use FastGas tanks or stick with standard 8g cream chargers. The answer depends entirely on your volume.
| 8g Cream Chargers | FastGas 640g Tank | |
|---|---|---|
| Setup | Screw into dispenser head | Requires regulator attachment |
| Cost per charge | Higher | Up to 60% lower |
| Best volume | Occasional to moderate use | Daily / high-volume use |
| Portability | Very portable | Less portable, fixed kitchen use |
| Waste | One cartridge per use | Single cylinder, less packaging |
Rule of thumb: if you’re using more than 2–3 chargers per day, a FastGas tank will pay for itself within weeks. If you use cream chargers occasionally at home, a pack of standard 8g chargers from our cream chargers collection is simpler and more convenient.
Who Should Use FastGas?
Restaurants & Fine Dining Kitchens
Professional kitchens producing espumas, whipped creams, and culinary foams daily will see the biggest cost saving from FastGas. The consistent gas pressure also gives more predictable results for technical preparations.
Cafés & Coffee Shops
Any café going through 10+ cream charges per day — for hot chocolates, frappes, desserts — will save significantly with FastGas versus individual 8g chargers.
Event Caterers
For events where large quantities of whipped cream or infusions are needed, a FastGas 640g tank is far more practical than carrying dozens of individual cartridges.
Heavy Home Users
If you’re a keen home baker or entertainer using cream chargers multiple times a week, upgrading to a FastGas tank will cut your costs and reduce packaging waste considerably.
How to Use a FastGas Tank
FastGas tanks do not screw directly into a standard cream dispenser like 8g chargers do. They require a compatible N2O regulator. Here’s the basic process:
Attach the regulator
Screw the N2O regulator onto the FastGas cylinder valve. Ensure it’s hand-tight — do not use tools.
Connect to your dispenser
Attach the regulator hose to your cream whipper’s charging port. Different dispensers use different connectors — check compatibility before purchasing.
Fill and charge
Add your cream or liquid to the dispenser, seal it, then open the regulator valve to charge. A single pull charges the dispenser — close the valve immediately after.
Shake and serve
Shake the charged dispenser 2–3 times and it’s ready to use. The tank remains connected and ready for the next fill.
Is FastGas Legal in the UK?
Yes — FastGas N2O tanks are completely legal in the UK for culinary use. Food-grade nitrous oxide has been used in professional kitchens for decades and is approved for use in food preparation under UK food safety regulations.
The Psychoactive Substances Act 2016 and subsequent 2023 amendments targeted recreational misuse of nitrous oxide. They do not affect the purchase or use of food-grade N2O products for culinary purposes. At CreamChargers.co.uk, all products are sold strictly for food use, and we comply fully with UK regulations.

Frequently Asked Questions
FastGas N2O tanks are used for whipping cream, creating culinary foams and espumas, infusing spirits and oils, and any application requiring food-grade nitrous oxide. They are the professional alternative to individual 8g cream chargers, offering significantly lower cost per use for high-volume operations.
A FastGas 640g tank contains approximately 80 equivalent charges compared to standard 8g cream chargers. The exact number of dispenser fills depends on your dispenser size (250ml, 500ml, or 1L) and how much gas each fill requires, but for a standard 500ml dispenser you can expect 70–85 fills per tank.
FastGas tanks require a compatible N2O regulator to connect to a cream dispenser — they do not screw in directly like 8g chargers. Most professional dispensers (iSi, Mosa, Liss) are compatible with the correct regulator. Always check regulator compatibility with your specific dispenser model before purchasing.
FastGas contains nitrous oxide (N2O), which is chemically the same gas. However, FastGas is food-grade N2O specifically manufactured and sold for culinary use. It is legal to purchase and use for food preparation in the UK. The recreational misuse of nitrous oxide is a separate matter — FastGas is sold strictly for kitchen use.
