Purity and Safety First
Whether you are getting a free air fill or a custom Trimix blend, we are uncompromising when it comes to purity and safety. Even though our air is free and our blends are expertly crafted, we maintain our compressor and filtration systems proactively to the highest possible standards. We ensure our air far exceeds pure air requirements, submitting regular lab samples for verification. This commitment to cleanliness applies to all our gases, because your safety is our top priority. Free air still adheres to these high standards.
Expert Cylinder Inspections for Peace of Mind
A safe fill starts with a safe cylinder. As a primary safety measure and professional standard, we diligently check hydrostatic test dates and require current annual visual inspections (VIP) for all tanks. If your tank is due for its VIP, we perform thorough inspections in-house. All tanks must have a current VIP to be filled at our facility, ensuring peace of mind for you and our staff. This is in addition to checking hydro dates, and we reserve the right to refuse fills based on safety concerns or lacking certifications.
