Infographic! The Best Biogas Blower for Your Digester Is. . .

Whether you're moving biogas in your digester that is on a dairy or poultry farm, landfill or wastewater treatment plant, ROTRON^® Regenerative Blowers are the best choice. Read the infographic below or download a printable copy now to find out why.


ROTRON Regenerative Blowers are...

• Designed by Bison^®, specifically for corrosive and hazardous applications
• Suitable for up to 1500 cubic feet per minute and up to a maximum pressure of 7 PSIG
• More corrosion resistant than competitive brands
• The safest in the market today, meeting stringent safety regulations
• Optimal for safety and increased gas recovery due to a variety of sealing options

• ROTRON Regenerative Blowers are made of aluminum, which is spark and corrosion resistant. Competitive blowers are made of steel or other metals. These materials are subject to corrosion.

• Oxidation doesn’t stand a chance with the stainless-steel nuts, bolts and other hardware that come standard on all ROTRON Chemical Processing (CP) Regenerative Blowers. Competitive blowers use cheap zinc-plated fasteners that are prone to corrosion.

• Chem Tough™ — a Bison proprietary process — combines the advantages of aluminum oxide ceramic and selected fluorocarbons to give ROTRON Regenerative Blowers unparalleled levels of chemical resistance, hardness, resistance, permanent lubricity and more.

• ROTRON Regenerative Blowers' full C face motors are designed to protect motor windings and bearings from corrosive gases and the airstream. Competitors often use half motors exposing these parts to corrosive gases, which can lead to blower downtime.

Reduce Leakage for Optimal Gas Recovery and Safety  

• The Lo-Leak™ Lip Seal prevents leakage at the motor shaft. RTV sealing compound is used to cut off all leakage paths at the blowers’ metal-to-metal surfaces.
• The Double-Faced Carbon Seal prevents further gas leakage at the motor shaft via a pair of face seals working against each other on opposite sides of a common mating ring.
• The Hermetically Sealed Mag Drive Seal has been an alternative for complete gas containment.

Explosive-Proof Motors Meet Stringent Safety Regulations  

• Safest in the Market
  ROTRON Regenerative Blowers' explosion-proof motors are rated for Class 1, Division 1, Group D areas at a minimum, making the motors the safest in the market. Most competitive blowers use Division 2 rated explosion-proof motors, which are not as safe as Division 1 motors.

• Thermal Protection
  All ROTRON Regenerative Blowers' explosion-proof motors have thermal protection, which shuts the motor off at specific temperatures via the customers’ control circuits.

• Most Complete Variety
  Bison strives to provide the most complete variety of explosion-proof motors, including Inverter-Duty motors that are ideal when using a VFD (Variable Frequency Drive) and Chemical-Duty XP motors that are perfect for handling corrosive and explosive gases.
