1/3 HP Blower 5/8 HP Blower

Blowers are the next alternative when our largest Linear Piston Air Pumps or Diaphragm Pumps will not suffice with adequate air volume for larger Fish Rooms. The smallest blower we now carry is a  .29 HP unit which can handle upwards of 100 outlets in moderately deep tanks. Blowers smaller than this do not have adequate pressure to supply air to deep tanks and in most cases our Linear Piston Air Pumps will outperform the smallest blowers (such as 1/8 HP). Since a piston has a fixed volume of air capacity due to the physical size of the cylinder and the maximum strokes per minute possible, there comes a point where large air requirements can not be met economically with the piston design (purchase cost of multiple piston units. Although Linear Piston Pumps have better pressure ratings than small Blowers, their output does not fall off as sharply as pressure increases over 1 PSI. Air distribution systems can be designed using 3/4” or 1” PVC pipe with the Linear Piston Pump. Regenerative Blowers are more like wind machines with  the ability to attain moderate pressures (due to the “regenerative” action of impeller/housing design) on the mid to larger sized units (1/3 HP+) and will produce extremely large volumes of air with the appropriate distribution system design. Note that even minimal restrictions in piping, air valves, airstones (if used) and dirty or undersized intake filter all will contribute to added back pressure on any air source. Therefore, water depth alone is not the only criteria that should be considered when selecting the correct Blower / Air pump. Minimum pipe size we recommend for smaller Blowers is 1 1/4” PVC with as few and gradual (shallow radius) turns where possible and utilizing a looped pipe system.

If a Blower is not being used to capacity, excess air should be “bled off”. Opening a large valve until desired flow is achieved is usually adequate, but more precise control and best efficiencies are obtained if a meter or a sensitive low pressure gauge is used to check lowest current draw or correct air pressure. Use our Bleed Exhaust Diffusers to reduce noise and control amount of air to bleed.

Better quality Blowers will provide good pressures while maintaining design flow rates. Good impeller and housing design provide lower noise levels than lesser grade machines. Superior motor construction will provide for longest life expectancy (MTBF). These are some of the criteria we used when deciding on our Blower line. As in all of our products we feel that buying quality pays off with “less aggravation, less maintenance and higher efficiencies”.

Features unique to this machine are:
Outboard Bearing - supports impeller to minimize stress and heat which leads to motor bearing failure on other models. Provides virtually maintenance-free operation.
Special Pressure Die Cast Impeller and Blower Housing requires large tooling investment to manufacture and provides a far better metalurgical density  for these important components than other manufacturer’s “Sand Casting designs”. Results in lower operating noise levels with less vibrations and better longevity.
Blower Engineered Electric Motor made specifically for the design requirements of this machine. This assures all parameters of the motor are made to match the Blower’s requirements. In other words, the motor is made for the right application from the start, not an off the shelf component made by another manufacturer and selected as an approximate fit. This unit’s motor has internal thermal overload protection and is designed for the utmost in operating efficiencies for the Blower it runs.
NOTES: Every aspect of this Blower speaks - German engineering and manufacturing! Larger sizes are also available in this design see RBSE-.6 below.
