SDD Direct Drive Series

The House Brush Aerator’s superior oxygen transfer and mixing capabilities make it the most efficient aerator for your wastewater treatment needs.  The increased aeration and mixing efficiencies provide lagoon, oxidation ditch, aeration basin, equalization basin, and aerobic digester applications the ability to operate with 25% to 75% less horsepower (references are available along with Certified Test Data). 

These energy savings alone allow for quick paybacks on new equipment.  Another payback with the House Brush Aerator is lower maintenance costs.  Simple lubrication and lubrication changes are needed during the operating year allowing plant personnel to concentrate on other day to day operations at your wastewater treatment plant.

 The House Brush Aerator can be used for municipal and industrial wastewater applications.  We have references for both municipal and industrial wastewater applications.  We have aerators in operation at the following: food processing plants, wineries, pulp/paper mills, textile plants, rendering plants, poultry plants, slaughterhouse plants, fish processing plants, and dairy operations.

 House Manufacturing Company, Inc. can assist you in your wastewater process design.  Please fill out our online wastewater applications data form below and we can provide you with horsepower recommendations, aerator layout (electrical layout if needed), model specifications, and a budgetary quotation.

• Teco-Westinghouse™ MAX-E1  with a 1.25 operating service factor.  Inpro™ Seals are standard on the MAX_E2/841 motors.
• Cast-iron construction with a zinc-chromate epoxy base with a blue finish.
• Stainless-Steel hardware and nameplate.
• Optional Motors are available at customer's request.

Motor & Gear Reducer Cover
 

• Our two-piece motor and gear reducer cover is fabricated from 14-gauge stainless steel.
• The hood is designed for long-lasting durability and easier access to the drive-train for routine maintenance.
• Optional splash guards and rotor cover are now available per customer request

• All rotors are fabricated from Schedule 40 pipe.  In most cases our schedule 40 pipe is twice as thick as our competitors rotor tube.
• Brushes are welded on both sides for durability and strength.
• 2 HP & 3 HP units have brushes that are 5" wide, all other horsepower units have brushes that are 6" wide.
• Blades operate at 6" to 8" submerged depth.
• Mild steel brushes are 10 Gauge and stainless steel brushes are 11 Gauge.
• Brushes vary in length from 11-5/16" to 14" depending upon the HP of the unit.
• Brushes are Robotically welded in a spiral configuration

• Grease Lubricated Corrosion Resistant Tail Shaft Bearing
• Corrosion resistant housing with Stainless Steel Grease Fitting or flip-top cover
• Stainless Steel Bearing Insert
• Bearing seals are Protected by Stainless Steel Flingers
• The Tail Bearing is Mounted in a Drip-Proof Bracket Assembly

• 16 Gauge 304L Stainless Steel floats
•  All floats are "closed-cell" foam-filled.
• 7 Gauge 304L Stainless Steel bands attach floats to the aerators mainframe.

• The main frame of the aerator is “welded” and “bolted” together using schedule 40 pipe.  The 2hp, 3hp, 5hp, 7.5hp, and 10hp brush aerators have a 3” schedule 40 pipe frame.  The 15hp, 20hp, and 25hp brush aerators have a 4” schedule 40 pipe frame.
• Adjusting rotor depth will determine amperage draw
• 304L Stainless Steel All Thread Adjusting Rods and Brass Nuts, adjust the depth of the rotor
• Pivoting Mooring System allows aerators to operate efficiently with fluctuating water levels at all times
