Integrated air regulator simplifies airflow-management and vibration-reducing rubber feet ensure quiet operation. The entire compressor unit is protected by the Airmax Composite Cabinet, which combines weather protection with a ventilation fan and high-density air intake filter to keep the compressor, cool, clean and dry. An elevated base protects hardware from flood or rainwater damage, and the cabinet is protected by a lifetime warranty (2 Year Warranty on electrical components). The PS30 system has max/running amps of 5.3/3.8 for a 115V system, and 2.6/1.9 for a 230V system. The max flow rate is 4.5CFM, and it can be operated in a pond with maximum depth of 21 feet.
