R-Series Chemical & Corrosion Resistant Blower System

Engineered for the safe and efficient extraction of hazardous chemicals and corrosive gases, the R-Series blower system is constructed from seamless, high-density polypropylene, ensuring exceptional durability, performance, and ease of installation. Designed for roof curb mounting, it is also suitable for standard air extraction applications.

Key Features & Benefits:

Superior Corrosion Resistance - Constructed entirely from high-density polypropylene for maximum longevity.
Non-Metallic Airstream - No metal components within the airstream, eliminating the risk of chemical degradation.
Reliable Motor Placement - UL/CSA TEFC/XPFC 1-phase and 3-phase motor is safely located outside the chemical airstream.
Enhanced Durability & Safety - UV-resistant, thermal-stabilized, and UL-94 fire-resistant compliant.
All-Inclusive Design - Comes equipped with a motor cover, outlet birdscreen, curb base, and a NEMA-4X or NEMA 7/9 disconnect switch.
Heavy-Duty Yet Lightweight - Built with 4-5mm thick, high-impact material for strength without added weight.
Eco-Friendly Construction - Made from 100% recyclable polypropylene, eliminating the need for chemical coatings.
Long-Lasting Performance - Resistant to degradation, flaking, peeling, and cracking.
Pre-Assembled & Tested - Fully assembled and tested before shipment for seamless installation.

Performance Specifications:

Airflow Capacity: 20 CFM – 6,500 CFM
Static Pressure Range: 0.10” – 8”

Ideal for environments requiring highly durable, chemical & corrosion-resistant, and maintenance-free exhaust solutions.
