Legacy 220 Capability

The Legacy 220 is capable of running with 20 to 80 lpm of oxygen feed, depending on the number of portable oxygen concentrators connected to it. It can power up to eight concentrators and is all controlled automatically. 20 lpm is an oxygen delivery rate equivalent to 1.5 K tanks every 8 hours. 80 lpm is an oxygen delivery rate equivalent to 6 K tanks every 8 hours. Oxygen delivery is up to 125 psi.

Active Compression Control

Active Compression Control (ACC) is a patented technology exclusive to OxygenFrog. The ACC senses process conditions throughout the compression cycle which lead to low oxygen purity, and eventual internal compressor damage, and it then acts to correct these improper conditions. Competing systems without ACC commonly suffer from lower purity oxygen and require frequent compressor rebuilds. The Legacy 220, with it's patented ACC technology, has a proven reputation for superior oxygen purity and compressor reliability.

Impure Oxygen Rejection

Oxygen concentrators, by their nature, produce impure oxygen for the first minute or two after they come on. All of OxygenFrog products automatically reject this impure oxygen, until the concentrators 'warm up', rather than compressing these impurities directly into the tank. The result is the maximum possible oxygen purity at your torch.

Restart Protocol Selection

The Restart Protocol selection feature on the Legacy 220, allows the user to easily change how aggressively the system runs. By selecting the 'Aggressive' Restart Protocol, the Legacy 220 will begin to refill the surge tank earlier in the compression cycle, maximizing the inventory of available oxygen.


- 220 VAC | 30 amp
- Powerful 1HP compressor
- 20lpm to 80lpm
- up to 8 concentrators

Other Required Equipment

The Legacy 220 will require a surge tank and oxygen concentrators. The Legacy 220 requires at least 20 lpm of oxygen feed. This could be any combination of 5, 8 or 10 lpm machines. The Legacy 220 can operate with as many as eight concentrators. A surge tank is required to accommodate extremes in oxygen demand. Surge tanks are common air compressor tanks and must be free of any flammable residue. A minimum of 60 gallons is recommended. Multiple tanks can be used as your glassblowing oxygen demand grows.

Warranty: One year parts and labor.
