MS-FRP & PP-FRP Blowers: A Complete Guide
Industrial exhaust systems often face harsh operating conditions where standard metal fans quickly corrode. MS-FRP and PP-FRP blowers are specialized solutions that combine strength, durability, and chemical resistance, making them ideal for handling corrosive gases and fumes.
What Are MS-FRP & PP-FRP Blowers?
MS-FRP Blower
Built with a Mild Steel (MS) structure for mechanical strength, lined or integrated with FRP (Fiber-Reinforced Plastic) in the airstream parts such as housing and impeller. This design resists corrosion while keeping the blower robust.
PP-FRP Blower
Uses Polypropylene (PP) parts (impeller or lining) combined with FRP reinforcement for additional strength. This is preferred in environments with aggressive chemical vapours where even FRP resins alone may degrade.
Technical Data Sheet (Typical Ranges)

Key Features
Corrosion-resistant construction with FRP or PP contact surfaces.
Lightweight design compared to stainless steel.
High efficiency impeller design for optimized airflow.
Customizable in size, capacity, and materials of resin/lining.
Low maintenance bearings (often oil bath or sealed type).
Versatile installation — available in direct or belt drive configurations.
Benefits
1. Longer service life in corrosive environments.
2. Cost-effective alternative to exotic alloys (e.g., SS 316, Hastelloy).
3. Energy-efficient operation when sized correctly.
4. Safer workplace by efficiently exhausting harmful fumes.
5. Reduced downtime due to minimal corrosion-related failures.
Applications
Chemical processing plants – handling acid/alkali vapors.
Laboratories & fume hoods – safe exhaust of chemical fumes.
Scrubber systems – circulation of gases in wet scrubbers.
Wastewater treatment – odor control and exhaust ventilation.
Pulp & paper industries – handling chlorine, bleaching gases.
Pharmaceuticals – clean room exhaust, solvent vapors.
Food & beverage – areas with high humidity or cleaning chemicals.
Frequently Asked Questions (FAQ)
Q1: What is the difference between MS-FRP and PP-FRP blowers?
MS-FRP uses Mild Steel structure with FRP lining, while PP-FRP integrates polypropylene parts for superior resistance to certain aggressive chemicals.
Q2: Can they handle high-temperature gases?
Most models are rated up to ~200 °F (90–100 °C). Beyond this, special resins or materials are required.
Q3: Are they suitable for outdoor installation?
Yes, FRP has good weather resistance, but UV-resistant coatings are recommended for long outdoor exposure.
Q4: What maintenance is needed?
Primarily bearing lubrication, vibration monitoring, and periodic inspection of impeller/housing surfaces.
Q5: How do I select the right blower size?
You need airflow (CFM), static pressure (W.G.), chemical composition, and temperature details to choose the correct model.
Conclusion
MS-FRP and PP-FRP blowers are vital for industries where corrosion is a challenge. By combining mechanical strength with chemical resistance, they provide a reliable, cost-effective solution for fume extraction and gas handling. With proper selection, installation, and routine maintenance, these blowers can deliver long service life, reduced downtime, and safe plant operation. If your operation deals with acidic fumes, chemical vapours, or corrosive gases, these blowers are not just an option — they are a necessity.
