Durable 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

Customer Questions
Do I need to oil or maintain the motor?
No, you don’t. The motor is permanently sealed and maintenance-free, so there’s no need for lubrication or frequent servicing. If you have any further questions, please don't hesitate to contact us. Thanks.
Is the R 35 blower noisy during operation?
No, it’s designed to run quietly. The forward-curve impeller helps move air smoothly and efficiently, so you get powerful ventilation without loud noise.
Can I install this blower myself, or should I hire a professional?
While it’s possible to install it on your own, we recommend hiring a professional. They can ensure it’s safely wired and properly sealed to prevent leaks and weather damage.
What type of controller works best with this fan?
A variable speed controller or VFD is ideal. It lets you easily adjust the fan speed to get the right airflow and noise level for your space. If you have any further questions, please don't hesitate to contact us. Thanks.
Does the R 35 come preassembled, or do I need to put parts together on-site?
The blower arrives fully preassembled from the factory, including the motor, housing, prewired disconnect, and exhaust guard. That means you can install it faster with less setup time on-site.
