See full warranty on Installation, Operation & Maintenance ManualDurable Materials & Construction
The R 35 blower is designed for rooftop use and built to handle corrosive and demanding environments where standard fans often fail. All parts exposed to airflow, including the housing, impeller, and internal surfaces, are made from thick-wall polypropylene for excellent resistance to acids, solvents, salts, moisture, and chemical vapors. To ensure long-lasting durability under sunlight, the polypropylene is reinforced with HALS (Hindered-Amine Light Stabilizers), which protect it from UV damage. Its lightweight plastic construction makes rooftop installation easier and reduces the need for heavy structural support while still delivering strong performance. As a direct-drive, forward-curve blower, the R 35 removes the need for belts or pulleys, cutting down on wear and maintenance. With no exposed metal in the airstream, it offers exceptional corrosion resistance and long-term reliability in harsh environments.
Whether it’s coastal salt spray, chemical fumes, or humidity stress, the R 35 is engineered to maintain performance and reliability in demanding outdoor settings where durability and corrosion resistance are mission-critical
