The Krendl 5200-DM Diesel Blower Machine is an industrial-grade fiber insulation machine and cellulose insulation blowing machine built for contractors who demand consistent, high-volume output and reliable performance. This diesel-powered model combines a rugged steel frame, powerful dual blowers, and advanced digital controls to handle the toughest insulation jobs with ease.
Dual 18-amp variable-speed blowers, an oversized 14″ airlock feeder, and an onboard generator—delivering up to 5,200 lb/hr of cellulose output.
Key Features and Benefits
- Dual High-Performance Blowers: Maximize output and complete jobs faster.
- Variable Speed Digital Controls: Precisely set blower and feed rates.
- Direct-Drive Transmission: Lower maintenance requirements and longer life.
- Large Hopper Capacity: Reduce refills and stay productive.
- 14″ Airlock Feeder: Moves high volumes of fiber or cellulose consistently.
- Rugged Powder-Coated Steel Frame: Withstands demanding jobsite conditions.
- Integrated Safety Systems: Includes emergency shutdown protection.
- Diesel Power: Onboard generator powers the entire system anywhere you need it.
How It Works
This fiber insulation machine uses a 14″ airlock and dual blowers to move insulation through a 4″ hose. Variable speed settings allow precise control of air pressure and material feed rates for open blow or dense-pack applications. The direct-drive system transfers power efficiently, reducing wear and increasing reliability.
Recommended Applications
- Retrofit attic insulation
- Dense-pack wall cavities
- New construction blowing
- Commercial and residential projects
