Durable Materials & Construction

The Storm 12 blower is crafted with all-polypropylene construction, meaning the housing, impeller, and airflow path are entirely made from corrosion-resistant plastic. This ensures excellent performance in chemically harsh or corrosive environments. To further enhance its durability in outdoor or UV-exposed settings, the polypropylene is stabilized with HALS (Hindered Amine Light Stabilizers), which mitigate UV degradation over time. The blower is offered in both single-phase and three-phase motor options to suit different power systems. Its forward-curved impeller design provides higher static pressure performance, making it suitable for ducted systems or exhaust lines with resistance.

Because of its direct-drive configuration, maintenance is simplified (no belts) and reliability is improved under continuous duty.


Suitable Applications for Plastec Storm 12 Forward Curve Blower

  • Chemical plants and labs – Designed to exhaust acidic fumes and gases in plants, labs, and processing areas with corrosion-resistant polypropylene build.
  • Scrubber systems – Fits into scrubbers and ducted exhaust lines requiring higher static pressure performance.
  • Lab Fume Extraction – Removes harmful gases from hoods, cabinets, and enclosures in research and cleanroom environments.
  • Water Treatment – Handles chlorine, bleach, and other treatment chemicals in wastewater facilities.
  • Marine & Coastal Use – UV-stabilized polypropylene resists salt, moisture, and harsh dockside conditions.
  • Battery & Storage Areas – Safely manages hydrogen and chemical off-gassing in battery, EV, and fuel cell rooms.
  • Industrial Processes – Supports plating, cleaning, and surface treatment lines where corrosive chemicals are present.
