The RBH Series regenerative blower from All-Star Products has reduced motor and bearing failures due to the high-temperature grease rated at 385 degrees F and Viton seals rated at 500 degrees F, providing an additional safety margin of protection due to periodic overloads. Class H 358-degree F motor insulation offers high thermal protection. When combined with its straddle-mounted bearing standard design, bearing failures are virtually eliminated. Lubricating the blower bearing can be done without disassembling the blower. External Zerk fittings are standard on all large single- and two-stage models. It provides flow up to 6,733 gpm and can handle pressures up to 11.5 psi. Chemical and marine-duty blowers with washdown features are available. 800/431-8258; www.all-star-usa.com.
