Roberts Oxygen in Baltimore: Medical and Industrial Gas Supply

Roberts Oxygen is a medical and industrial gas supplier serving the Baltimore region from a retail location that stocks compressed gases, regulators, and related equipment for healthcare facilities, welding shops, laboratories, and individual customers.

What Roberts Oxygen actually is

Roberts Oxygen operates as a full-service gas distributor with both walk-in retail and delivery capabilities. The business supplies medical-grade oxygen, nitrogen, argon, acetylene, and specialty gas mixtures to hospitals and clinics, as well as to welders, fabricators, research institutions, and home healthcare patients. Unlike national chains or online retailers, Roberts maintains local inventory and technical staff familiar with Baltimore-area regulatory requirements, hospital protocols, and the specific pressure specifications that different trades demand.

Gases, equipment, and pricing

Roberts stocks compressed gases in multiple cylinder sizes. Medical oxygen cylinders (the smallest portable tanks used in home care) typically run $40 to $80 per fill, with refill turnaround measured in hours rather than days. Larger industrial cylinders used in welding or metal fabrication cost $25 to $50 per refill depending on gas type and purity level. Specialty gases and rare mixtures carry higher per-unit costs; confirm current pricing by phone, as rates fluctuate with supplier costs.

Beyond gases, Roberts carries regulators, pressure gauges, flowmeters, fittings, and safety equipment. A single-stage regulator for oxygen or inert gases runs $30 to $80 new; dual-stage models cost $100 to $200. Regulators can be repaired on-site or purchased refurbished at 20 to 40 percent below retail. The shop also rents welding carts and cylinder racks by the week or month for contractors who need temporary equipment without capital outlay.

How Roberts compares to other Baltimore gas suppliers

Roberts competes primarily with national suppliers like Airgas and Praxair, which operate distribution centers in the area. National chains offer broader geographic delivery networks and can handle large institutional contracts; however, they typically require 24-hour notice for most orders and charge delivery fees that make small or emergency fills uneconomical. Roberts prioritizes walk-in and same-day service. A welder needing a cylinder filled at 2 p.m. on a Thursday can grab a filled tank immediately; the same request to a national distributor often means waiting until the next scheduled delivery route.

Local medical supply companies in Baltimore sometimes handle oxygen for home care patients, but they do not stock or repair industrial regulators or provide acetylene for welding. Conversely, welding-supply specialty shops in the region (such as those in Canton or Dundalk) stock gases but typically do not serve medical clients or maintain the regulatory certifications required for hospital-grade oxygen purity. Roberts bridges both worlds.

Who it suits and who it does not suit

Roberts is built for medical professionals managing patient oxygen at home or in small clinics, welders and fabrication shops, research labs requiring calibrated gas mixtures, and maintenance departments in industrial facilities. The retail location and phone ordering system work well for routine refills and small emergency needs.

Roberts does not suit large hospitals with centralized gas delivery contracts (they use national suppliers) or customers who need gases only once or twice yearly and are willing to order weeks in advance. It also does not stock consumer-grade products like propane for grills or heating; those are available at hardware chains.

What the first visit involves

Walk in with your empty cylinder or regulator needing service. Bring the cylinder's tag or label, which lists the valve type and pressure rating. A staff member will verify safety inspection dates (cylinders must be tested every five to ten years, depending on type). If your cylinder passes inspection, they will fill it on-site, usually within 15 to 30 minutes. If you need a regulator repaired or calibrated, you can often leave it and pick it up the same day or next morning. For customers without an account, expect to provide identification and a phone number for future orders.

Hours, parking, and location

Roberts Oxygen operates Monday through Friday, 8 a.m. to 5 p.m., and Saturday, 9 a.m. to 1 p.m.; it is closed Sundays. Street parking is available near the location. The shop does not deliver on Saturdays. Verify current hours by phone before a weekend visit, as seasonal staffing occasionally changes the Saturday schedule.

Roberts Oxygen fills a gap that neither national chains nor general retailers address: same-day service, technical know-how for both medical and industrial applications, and repair capability for regulators and equipment. For Baltimore welders, home-care nurses, and lab managers who need gases reliably and locally, that proximity and expertise makes the difference.
