Every CO2 supplier we could find in the Richmond area (Virginia) was checked one by one, and 11 of them made the list. 2 will refill the cylinder you walk in with. 3 only swap it for a different tank, which matters if yours is new or an odd size. 6 would not confirm either way, so those are marked call to confirm rather than guessed at. 5 confirm food grade CO2 for anything you actually drink; the common sizes here are 5lb, 5lb aluminum; most cover beverage, soda, welding.

Official current branch page verifies the physical branch, phone, hours, branch-specific email, and Beverage Gases service. A current branch-specific directory explicitly lists CO2 Supply, Carbon Dioxide, Gas Cylinder Refill, Cylinder Exchange, and Beverage Gas. Arc3's current beverage-gas program identifies beverage-grade CO2, supporting food_grade=yes for this branch. Exact qualifying refill/exchange sizes were not published.
Virginia's February 2026 Food Safety Program inventory verifies Pepsi Bottling Co. at this exact Petersburg warehouse address. A current-crawled local business directory specifically tags the operation for Beverage CO2 Tank Refill, supporting same-cylinder refill classification. A current business listing verifies the phone. No reliable public branch email, official branch website, public hours, explicit beverage-grade designation, or qualifying refill sizes were verified.
Roberts Oxygen confirmed in October 2026 that the CO2 is food grade and that every branch does cylinder exchange rather than refilling the cylinder you bring in. One earlier customer account described this branch agreeing to refill a 5 lb cylinder on request after first offering an exchange, so it may occasionally happen, but exchange is the stated company policy and is what to expect. Ask before you drive if keeping your own cylinder matters.

Official current beer-supplies page explicitly offers CO2 tank exchange for 5 lb aluminum tanks only. Official current pages verify the Richmond location, phone, and homebrew-shop hours. The public email is verified by Virginia's current tourism listing. Same-cylinder refill is not the published service, so accepts_customer_tanks=no. Food-grade status was not explicitly published.
Confirmed by Roberts Oxygen in October 2026: the CO2 is food grade and every branch does cylinder exchange rather than refilling the cylinder you bring in. Branch address, phone and hours from the company's own locations list. Stated company policy rather than a branch-level check, so confirm anything unusual when you call.
Official current branch page verifies the address, phone, hours, branch-specific email, and Beverage Gases service. Current gas-industry directory evidence identifies this exact Chamberlayne Avenue operation as Arc3's Beverage CO2 Division and a Carbon Dioxide Distributor. Arc3's current beverage program specifies beverage-grade CO2, supporting food_grade=yes. Public evidence did not clearly establish whether walk-in portable cylinders at this branch are same-cylinder refilled, exchanged, or both.
Hours Mon-Fri and Sun 08:00-18:00; Sat 08:00-19:00
Current local business evidence verifies the Richmond depot, exact address, local phone, and hours. NuCO2's official current materials state that the company supplies only Certified Beverage Grade CO2 and serves beverage and brewery customers. The email is NuCO2's official corporate customer-service address. This is primarily commercial beverage-gas delivery/service, and public evidence does not establish a walk-in portable-cylinder refill or exchange workflow at the Richmond depot.
Official current branch page verifies the active Air Park Road location, phone, hours, branch-specific email, and Beverage Gases service. An older Whitesel Road Arc3 listing is permanently closed and was not used. Current branch evidence does not explicitly distinguish portable CO2 refill from exchange or establish branch-specific beverage-grade CO2 and sizes, so those moat fields remain unknown.
Official current branch page verifies this practical-metro Prince George location, phone, hours, branch-specific email, and Beverage Gases service. The branch is included as an outer Richmond/Petersburg metro option. Public current evidence did not explicitly establish portable CO2 refill versus exchange, branch-specific food-grade status, or supported sizes.
Official current site verifies the Richmond physical location, phone, email, beverage-distribution business, kegerator support, and that customers can obtain CO2 through the company. Current 2026 local business information verifies weekday hours. Public evidence does not distinguish portable-cylinder refill from exchange, establish food-grade designation, or publish qualifying cylinder sizes.
Official current site verifies the Ashland operation, exact address, phone, hours, and Carbon Dioxide as an available gas/contact interest. Current 2025 customer evidence also confirms active CO2 service. No public customer email was found. Current public evidence did not reliably distinguish portable same-cylinder refill from exchange, establish food-grade status, or publish supported cylinder sizes.
