The Air Level Master™ is a float valve system that regulates the activation of Satellite Mixing Stations (sold separately) to automatically maintain a constant supply of ready-to-use chemical solution in a paired day tank (sold separately). When the solution in the tank drops below a pre-set level, the primary float valve will open to allow compressed air to flow through and activate one or more Satellite Mixing Stations to quickly replenish the solution. The system cycles continuously and a secondary fail-safe float prevents overfilling.
