The Ametek Rotron DR 303 series regenerative direct drive blower is designed for commercial spas, as well as hotels/motels, health clubs, and condominiums. These applications require a continuous duty blower with low noise levels (compliant with OSHA standards). The Ametek Rotron DR 303 series is manufactured in the USA. It is compliant with ISO 9001 requirements as well as with CE Marking standards (Declaration of Conformity available upon request). The blower housing is composed of cast aluminum with cast iron threaded flanges, and the motor is UL and CSA approved, as it contains permanently sealed ball bearings and Class B rated thermal protection.
Additional options of the Rotron DR regenerative blower include: (a) corrosion resistant surface treatments and sealing options; (b) remote drive-motorless-models; and (c) slip-on or face flanges for application-specific needs.
The maximum operating temperature for the motor should not exceed 140°C (Class F rated motors), and the maximum temperature of the outlet air for the blower should not exceed 140°C (this includes air temperature rise plus inlet temperature). The maximum pressure and suction/vacuum figures seen in the air flow x pressure performance curves (see datasheet, page 2) are based on a 40°C inlet and ambient temperature.
