RBH Series regenerative blowers from All-Star Products reduce motor and bearing failures due to the high-temperature grease (rated 385 degrees F) and Viton seals (500 degrees F) used. This provides an additional safety margin of protection due to periodic overloads. When combined with existing Class H (358 degree F) motor insulation and straddle-mounted bearing standard design, bearing failures are virtually eliminated. Lubricating the blower bearing is possible without having to disassemble the blower. External Zerk fittings are standard on all large single-stage models and on all two-stage models. They provide flow up to 900 scfm and 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.
