Blower Comparison Chart |
| Features | RBS | Sonic | Paxton | Advantage |
| Ceramic Hybrid Bearings | Yes | No | No | Ceramic balls always run cooler than steel balls prolonging lubricant life. |
| Vibration levels run 2-7 times lower than with same size steel bearings. | ||||
| Service life of ceramic balls is 2 to 5 times greater than conventional steel balls. | ||||
| Maximum running speed is 40% greater than steel ball bearings. | ||||
| Steel balls will cold weld to steel rings even under normal load and lubricant conditions. This reduces lubricant and bearing life. | ||||

| Reduced maintenance expense. | ||||
| 16 Groove Micro-V Belt | Yes | Yes | Yes | Wider belt contacts more of the pulley surfaces resulting in less slippage, lower heat, and longer belt life. Reduced maintenance expense. |
| Steel Bearing Housing Standard (Electroless Nickel Plated) | Yes | No | Yes | Higher tensile strength than aluminum giving better stability and lower vibration than aluminum bearing bore. Lower coefficient of thermal expansion giving bearing a better fit in bore when blower is hot. Longer blower life. |
| Stainless Steel Blower Pulley | Yes | Yes | No | More wear and corrosion resistant than plated metal. Reduced maintenance expense. |
| Steel Motor Pulley (Electroless Nickel Plated) |
Yes | No | No | Three-four times the weight of aluminum pulley causing slower startup speeds. Reduced wear on blower/drive assembly. Not damaged when belt slips. Lower maintenance expense.
|
| Cooling Fins on Bearing Housing | Yes | No | Yes | Reduces operating temperature of bearing Reduces operating temperature of bearing |
| PTFE Shaft Seal on Both Sides of Bearing Assembly | Yes | No | No | PTFE Shaft Seal on Both Contaminants are the #1 cause of blower failure. Republic’s proprietary seal design reduces blower failure over the competition. Longer blower life. |
| High Performance Impeller Design | Yes | No | Yes | The Republic Blower moves more air per rotation than the competition.
This translates to lower operation speeds with equal performance
and significantly increased blower life. |
| Largest Tension Pulley | Yes | No | No | Slower tension pulley speed greatly increases bearing life. Lower maintenance. |
| Two Bearings on Tension Pulley with Seals to Stop Contaminants | Yes | No | No | Longer life than the competition. Lower maintenance expense. |
