Allegro 20in High-Velocity Jet Fan (11000 CFM)

Description

Allegro 20in High-Velocity Jet Fan (11,000 CFM)

The Allegro 20-inch High-Velocity Jet Fan is a powerful industrial-grade ventilation solution designed for confined space ventilation, construction site airflow management, and hazardous environment air circulation. Engineered for high-performance airflow delivery, this jet fan produces up to 11,000 CFM (cubic feet per minute), making it ideal for removing fumes, dust, heat, and stale air while supplying fresh air into enclosed or poorly ventilated areas.

Built with a durable steel housing and high-efficiency aerodynamic blades, the Allegro jet fan ensures strong, directed airflow with minimal turbulence. Its compact and portable design allows for easy positioning in tunnels, tanks, manholes, and underground construction environments. The fan is engineered for continuous-duty operation, providing reliable performance in demanding industrial and safety-critical applications.

This unit is widely used in construction, industrial maintenance, utility work, and confined space entry operations where proper ventilation is essential for worker safety and regulatory compliance.

Designed with a durable steel housing and high-efficiency motor, it ensures safe and reliable air circulation in demanding environments.

Before ordering the Allegro 20in High-Velocity Jet Fan (11000 CFM) from Allegro, review the points below against your actual site conditions and workload. Published specifications describe the equipment under test conditions, and real-world performance depends on how closely your application matches those conditions. Buyers in the United States, Canada, and Asia should also confirm local voltage and frequency requirements, applicable safety or emissions standards, and freight or import logistics for the destination before finalizing an order.

What to Check Before You Buy

• Match required CFM to the space volume and target air changes per hour for the specific application.
• Check ducting size and static pressure ratings are compatible with the fan or blower's rated output.
• Confirm filtration stage (if any) matches the contaminant being controlled.
• Review noise rating and power requirements against the installation environment.

What is static pressure and why does it affect ventilation equipment sizing?

Static pressure is the resistance airflow encounters moving through ducting, filters, and fittings. A fan's rated CFM assumes a specific static pressure – actual airflow delivered drops as system resistance increases, so ducting length and filtration need to be accounted for, not just the fan's free-air rating.

For sizing help across the full Ventilation Equipment Supplies category, compare specifications side by side before committing to a specific model, and confirm current pricing, availability, and freight details for your location. Keep the supplier data sheet and any acceptance criteria on record for future maintenance and replacement decisions.
