UV degradation is minimized with the addition of Hindered-Amine Light Stabilizers (HALS), enhancing durability and life expectancy even in high-sunlight installations. With a compact footprint and a lightweight yet durable design, the R 15 blower ensures simplified installation and long-term reliability. Whether you're dealing with aggressive fumes or harsh outdoor exposure, this unit delivers superior performance with minimal maintenance.

Key Features:

  • All-polypropylene construction for superior resistance to corrosion, acids, and harsh chemicals
  • Integrated HALS (Hindered-Amine Light Stabilizers) for enhanced UV protection
  • Horizontal discharge with roof curb or sidewall mounting compatibility
  • Pre-configured for mounting on standard 21" x 21" roof curbs
  • Includes factory pre-wired disconnect switch and protective exhaust guard for safety and convenience
  • Factory pre-assembled to reduce installation time and labor
  • Lightweight, low-profile design for aesthetic and structural flexibility
  • Optional 18" and 24" roof curbs available for versatile installation heights

Durable Materials & Construction

The Plastec R-15 blower is specifically designed for rooftop or exterior mounting in corrosive, chemical, or fume-laden environments. Every surface exposed to the airstream, including the housing and impeller, is molded from heavy-duty, UV-stabilized polypropylene. This material is highly resistant to acids, salts, chemical vapors, and moisture, making the blower far more durable than traditional metal fans that can rust or corrode over time. Polypropylene construction also ensures long-term performance in outdoor environments. The addition of Hindered-Amine Light Stabilizers (HALS) protects against ultraviolet degradation, so the blower maintains its strength and integrity even under constant sunlight. Unlike metal housings that may dent or oxidize, polypropylene resists chemical attack and impact damage, extending the overall service life of the unit. Its lightweight yet rugged construction makes rooftop handling easier without sacrificing durability.

In summary, the R-15 is built to withstand harsh environments, resist corrosion, UV damage, and chemical attack, while consistently providing reliable exhaust ventilation for demanding rooftop or wall-mounted installations.


Suitable Applications for Plastec R 15 Polypropylene Blower

  • Rooftop Exhaust Systems: Ideal for removing chemical or corrosive fumes directly to the outdoors, protecting indoor air quality.
  • Wall or Sidewall Exhaust: Commonly used in industrial facilities where corrosive gases or vapors are present, offering reliable and safe ventilation.
  • Laboratories & Fume Hoods: Provides efficient venting of hazardous laboratory fumes and chemicals, ensuring compliance with safety standards.
  • Marine & Coastal Environments: Built to withstand salt spray, humidity, and moisture while maintaining long-term durability in harsh coastal conditions.
  • Wastewater & Treatment Plants: Designed to exhaust moist, corrosive, and chemically aggressive air typically found in pump rooms and chemical storage areas.
  • Industrial HVAC & Processing Facilities: Delivers chemical-resistant ventilation for demanding HVAC exhaust systems in factories, plants, and processing areas.

Customer Questions
What makes the Plastec R-15 different from traditional metal roof blowers?
The R-15 is made from durable polypropylene that won’t rust or corrode like metal. It’s a great choice for areas exposed to chemicals, salt air, or moisture.
Is the R-15 blower energy efficient?
Yes. Its direct-drive motor delivers power straight to the fan, helping reduce energy loss and making it more efficient than belt-driven models.
Can the blower be mounted on a wall instead of a roof?
Yes. Although it’s mainly designed for rooftop use, it can also be installed on a wall if it’s properly supported. If you have any further questions, please don't hesitate to contact us. Thanks.
Can it run continuously without issues?
Yes. The R-15 is built for continuous use as long as it’s installed correctly and the airflow isn’t blocked.
How durable is the housing material?
The blower housing is made from thick, impact-resistant polypropylene that holds up well even in demanding industrial or coastal environments.
